Psychiatric Drugging: Forty Years of Pseudo-Science,
Self-Interest, and Indifference to Harm
David H. Jacobs
Centre for the Study of
Psychiatry and Psychology - Bethesda MD
The "modern" era of psychiatric drug treatment
began with the introduction of chlorpromazine into the chaotic mental hospital
setting in the 1950s as a new psychotropic agent for controlling excitement,
agitation, and aggressivity. In that setting the urgency of management problems
operated to shrink the complexity of the patient as a psychosocial being down
to specific "symptoms" targeted for chemical subjugation. From this
beginning - a chemically produced quieting or "tranquillisation" -
there emerged a revitalised psychiatric movement to expand the "strictly
medical" understanding and treatment of psychological disturbance that
acknowledges no limits. This state of affairs has achieved a position of
dominance and respect in the mental health industry, based upon social forces
operating within psychiatry as a profession and outside of psychiatry in the
larger political-economic realm. The catastrophe of widespread and expanding
medically-produced disease has failed to alarm psychiatry into taking stock of
the determinants of the catastrophe - indeed the existence and magnitude of the
tragedy is barely recognised within psychiatry. This conclusion is illustrated
by detailed examination of the psychopharmacologic agents alprazolam (Xanax)
and fluoxetine (Prozac).
In 1970, Pierre Deniker, who along with Jean Delay
introduced chlorpromazine into psychiatry (in 1952), published a retrospective
on the discovery of chlorpromazine and reviewed subsequent progress in
psychopharmacologic treatments of "mental disorders." Deniker
referred to the use of centrally active drugs to treat mental conditions as
providing treatment "in a strictly medical sense," and he clearly
regarded this as a triumph for medicine. As to the question of aetiology why is
it that the patient has wound up in this unfortunate condition? Deniker takes
for granted that this is a puzzle whose solution lies in the realm of
conventional medical research into disease causation. Both erroneous ideas -
that "functional" psychiatric disorders are in reality due to organic
morbidity, and that disturbances in the psychological realm can be successfully
treated pharmacologically - can be regarded as the pillar upon which
contemporary biopsychiatry rests.
My primary purpose in this paper is to critically examine
the latter pillar, that is, the conviction that a happy outcome can result from
bypassing the social-interpersonal route of influencing a person's
psychological life and substituting direct chemical intervention in
neurophysiology. In short, I aim to evaluate the claim that - etiopathogenesis
aside - it is simply an empirical fact that psychiatric patients do benefit
from pharmacological treatment, and moreover that the benefits of such
treatment definitely outweigh the (organic and psychological) costs. My thesis
is that the pharmacological approach must fail in its clinical aims and also
damage patients because (a) any drug potent enough to alter psychological life
is of necessity toxic and pathogenic, since to be effective it must disrupt
normal brain physiology, and (b) the disruption of normal neurophysiological
mechanisms, including integrative and homeostatic mechanisms, will eventually
exacerbate the original symptomatology or transform it via drug-produced
neuropathology.
In the first part of this paper, I illustrate both aspects
of the above thesis by reviewing what is known about the effects of
"antipsychotic" drugs, since a good deal of the "new"
(i.e., post-chlorpromazine) biopsychiatry's reputation rests upon the alleged
efficacy of pharmacologic agents designated as "antipsychotic." This
review will naturally raise the question of why psychotropic drugs are being
advanced ever more vigorously by the profession of psychiatry. The answer to
this question will be found outside of scientific reasoning and evidence in
sources of influence which shape all large scale social developments. In the
second part of the paper, I go over the same ground in even more detail with
regard to two recently introduced psychotropic agents (Xanax and Prozac). The
second part of the paper will show that the catastrophic consequences of the
"antipsychotic" drugs has done nothing to dampen enthusiasm for the
"strictly medical" approach to treatment. I do not use the word
catastrophe lightly or merely rhetorically. Mosher and Burti (1989), for
example, remark that American psychiatry has "created a new species, the
tardive dyskinesic" (p. 3; note that Loren Mosher is a former NIMH Chief
of the Centre for Studies of Schizophrenia). While "tardive"
dyskinesia is so named because this form of neurological motor dysfunction does
not typically appear immediately or soon after neuroleptic treatment begins
(tardive means "late appearing"), Casey and Keepers (1988) point out
that acute motor and mental impairments occur in up to 90% of patients treated
with neuroleptics. Such acute neurological syndromes - produced by the
"medicine" itself - may then be treated with additional
"medication," but even if this does ameliorate the original
medication-produced morbidity in some patients, the long-term consequences of
adding still other centrally active drugs is unknown and is simply not a topic
of investigation.
It might at first glance appear surprising that the
"antianxiety" and "antidepressant" drugs have been applied
so successfully to patient groups that are in the main less impoverished,
stigmatised, and socially degraded than the typical recipient of
"antipsychotic" drugs, Although this is indeed a complex topic, I can
mention at least two pertinent part-explanations in my introductory remarks:
(a) the cultural and professional success of medicine does not actually depend
upon the safety and "efficacy of medical treatment (Broadhead and
Facchinetti, 1985; Cochrane, 1972; Dubos, 1965; McKeown, 1976; Roper,
Winkenwerder, Hackbarth, and Krakauer, 1988; Silverman and Lydecker, 1980); (b)
the push from within psychiatry to emphasise drug treatment and the
"medical basis" of psychological distress has only been amplified
since the introduction of chlorpromazine into America in 1954 (see ahead).
What Can Be Learned From
Forty Years Experience With "Antipsychotic" Drugs
Drug-Produced Effects "On the Side"
Non-medical psychotherapists (such as myself) may find it
puzzling how a drug-effect like akathisia (a term used to describe very
pronounced drug-produced restlessness and agitation) can be addressed by
psychiatrists as a "side effect," and in this manner be virtually
dismissed as tangential to the clinical efficacy of a medicine (e.g."
chlorpromazine). Although akathisia can vary in severity when it is present,
the term is only used to designate a drug-produced neurotoxic effect when the
patient is clearly suffering (based upon complaints and/or clinical
observation). In fact, akathisia can become so unbearable that it directly
precipitates impulsive suicide attempts and successes (Drake and Ehrlich, 1985;
Shaw, Mann, Weiden, Sinsheimer, and Brunn, 1986; Shear, Frances, and Weiden,
1983; Van Putten and Marder, 1987). Reading Deniker's 1970 retrospective, in
which he makes it clear that parkinsonism, akathisia, akinesia (profound
difficulty in initiating movement), and other drug-effects of chlorpromazine
were recognised in the early days of its clinical trials, it would appear that
a side effect is any drug-effect that does not ameliorate the clinical
symptom(s) or sign(s) for which its use is intended. The upshot is that, within
the medical framework, a drug like chlorpromazine is considered
"effective" for treating (say) psychotic agitation even though it
simultaneously produces parkinsonism and other neurological syndromes.
In retrospect, the modern era of psychiatric drugs got off
to the worst possible start due to its clinical application in the mental
hospital situation and for the purpose of quieting and rendering more tractable
severely agitated or violent patients. The urgent need to quiet and render
agitated patients more manageable presented an irresistible temptation to
reduce the totality of the patient's psychic life, subjectivity, and social
functioning to the level of custody (read: becoming less trouble for the
custodians) [Elkes and Elkes, 1954; Kalinowsky, 1958; Lehmann; 1955, Lehmann
and Hanrahan, 1954]. In those early days there was no talk at all of
chlorpromazine, etc. having "antipsychotic" properties - in fact,
this was explicitly denied (which of course raises the question of how the very
same drugs emerged in the 1960s as "antipsychotics"). Indeed,
conditions in the US state mental hospital system were so barbaric (Kiesler and
Sibulkin, 1987; Valenstein, 1986), and expectations concerning the fate of
hospitalised patients so dismal (Klerman, 1978; NIMH Psychopharmacology Service
Centre Collaborative Study Group, 1964), that the discovery of chlorpromazine
and related drugs could be likened to the use of morphine in a rough field
hospital for severely wounded soldiers. In short, psychological recovery or
even substantial improvement was not at issue; at issue was finding some
substitute for the straightjacket and equivalent methods, and for the
cumbersomeness, morbidity, and mortality that went along with other
"somatic" methods of palliation/control available at the time
(insulin shock and coma, metrazol shock, prolonged barbiturate sleep, lobotomy,
etc.). This hardly seems an auspicious start for a revolutionary
"remedicalization" of psychiatry, since as Scull (1984) rightly
points out, at best the new psychotropic agents introduced in the 1950s could
accomplish little more than a quieter hospital environment. However, potent
political, economic, and professional forces were (and are) at work which
seized upon the new "antipsychotic" agents as the basis for expanding
pharmacologic treatment to "disorders" that did not even officially
exist in the 1950s (see ahead).
As mentioned above, one immediate consequence of treating
specific symptoms "in a strictly medical sense" was (and is) that a
drug can be regarded as "effective" despite the fact that it
simultaneously produces unwanted and even disastrous additional consequences.
Unwanted consequences are treated as part of a cost-benefit package that must
enter into clinical decisions about the use of any medicinal drug. The
"cost" of a drug in terms of its clinical use is obviously a complex
matter of judgement. The point I make at this juncture is that the
"strictly medical" drug treatment of unruly mental hospital patients
did not include any interest at all in the patient's own views on the costs
versus the benefits of the treatment. Thus for a long time - and in many ways
up to the present - it did not seem at all contradictory (within psychiatric
thought) to state that neuroleptics were clinically effective despite producing
agitation and anxiety (akathisia), or apathy and indifference, or that they
made even simple actions too effortful to attempt, rendered thinking painfully
slow and laborious, etc.
The issue of "side effects" still requires further
refinement. Although an unwanted effect like parkinsonism or dystonia (painful
muscular contractions or spasms) may be identified as a side effect, subjective
reactions to adverse drug effects are passed over without recognition or
comment. Thus what is absent from psychiatric reports is discussion concerning
what it means to patients to find themselves unable to move, to control the
shaking of their limbs, to be forced into bizarre postures due to painful
muscle contractions, and so on. In short, suffering is excluded from what is
recognised as a side effect. Likewise excluded from recognition is the impact
that side effects may have on the person's status as a social being, and how
impairment in the social-interpersonal realm may act back upon the experience
of living (e.g., parkinsonism may impair the ability to swallow, resulting in
copious amounts of saliva collecting in the mouth and overflowing in streams
from the lips and down the chin). Drug-induced suffering, both the suffering
directly produced by the drug itself and the further suffering evoked by the
experience of impairment, disability, social stigma etc., are discussed
obliquely in terms of how well or not the drug is tolerated, usually in terms
of patient compliance. The pervasive phenomenon of poor compliance with
neuroleptic medication led directly to the development of new injectable
"depot" forms of neuroleptics, a technical advance devised precisely
for the purpose of outmanoeuvring subjectivity (meaning that left to their own
devices many individuals will not take their medication, usually a decision
made on the basis of how the medication makes them feel and the impairments
that the medication produces).
Occasional papers which acknowledge an inner world of
subjectivity which cannot be dismissed out of hand represent the extreme
liberal wing of psychopharmacologic thought (Diamond, 1985, and Van Putten,
May, Marder, and Wittman, 1981, can be cited as rarities). Again, concern for
the individual's experience as a complex psycho-social being - which would
seem, would it not, to be the actual subject matter of psychiatry - is largely
eliminated from biomedical treatments. Thus, it has been left to successful
litigation to bring the consequences of neuroleptic treatment forcefully to the
attention of psychiatry (Brown and Funk, 1986; Deveaugh-Geiss, 1979; Gualtieri
and Sprague, 1984).
Psychopharmacologic Treatment Revives the
Conviction That What Is Being Treated Is a Medical-Organic Condition
It is also obvious from Deniker's paper that focusing attention
on 'symptoms" which most lend themselves to using descriptive language
drawn from or inspired by organic medicine ("thought disorder,"
"pressured speech", "hallucinations," etc.) has the effect
of rendering the patient's social history and present social circumstances
irrelevant. In this manner the usual fact that virtually nothing is known or
understood about the patient's social-psychological history and course of
development becomes unproblematic from a practical treatment perspective. That
point is made with some candour near the end of the influential 1964 research
paper published by the NIMH Psychopharmacology Service Centre Collaborative
Study Group, entitled "Phenothiazine Treatment in Acute
Schizophrenia." Under the heading "Implications for Public Health
Programs," the authors advance the idea that both short and long-term
treatment of schizophrenia via phenothiazines eliminates the need for
"highly trained" psychotherapy personnel (p. 259). The concluding paragraph
is devoted to thanking various private, for-profit pharmaceutical companies for
donating the phenothiazines under "investigation." In 1970 Deniker
was still willing to acknowledge that successful drug treatment in
schizophrenia and other "mental disorders" occurs despite unknown
aetiology and pathophysiology. In practice, of course, drug treatment for
specific symptoms - the "strictly medical" approach - attracts
attention to research into just how and why the drugs produce the
psychopharmacological and physiological effects that they do, and also into
ever more technical searches for the abnormal physiology assumed to be
responsible for the emergence of the symptoms in the first place. At this
point, I will simply advance the idea that both from the perspective of the
medical-hospital-pharmaceutical industry, as well as the funding and research
interests of the biological science community, the conviction that
physiological dysfunction is the fundamental case of mental disorder is too
valuable to abandon. As a practical matter the "strictly medical"
approach to mental disorder - chemical treatment of narrowly defined symptoms
and/or signs - dissolves the complexity of what psychopathology is or how it
develops by establishing a project that fits into the conventional medical paradigm.
This brings us back to the problem at hand - the ensuing epidemic of iatrogenic
damage.
Longer-Term, Irreversible Drug-Produced
Neurological and Psychological Damage
Looking back to the 1950s, it appears that that "new
era's" origin in the mental hospital situation, with success defined as
the management of patients, in addition to the prevailing nihilism of prognosis
(NIMH Psychopharmacology Service Centre Collaborative Study Group, 1964. p.
256), started the path downward to the present predicament. Schizophrenia was
treated as if it were a uniformly chronic and deteriorating condition, which
made it justifiable in the minds of psychiatrists to apply "heroic"
medical measures. The justification for medical treatment with what were clearly
neurotoxic substances was no different than the justification for lobotomising
the brain or resorting to other heroic (i.e., desperate) medical interventions
( see Valenstein, 1986, for a review of pre-chlorpromazine treatments of
schizophrenia, especially lobotomy). Nowhere in Deniker's 1970 retrospective
does he entertain the possibility that the dismal fate of schizophrenics could
in any way be connected to the brutal and inhumane conditions of life to which
they were subjected in hospital, although he makes no bones about hospital
conditions when he first put chlorpromazine to use. It would seem that only the
conviction that schizophrenia (and other conditions) is a disastrous and
ineluctably progressive organic disease would allow him to admit the following:
"...it might have been feared that these drugs, whose
action compares with that of encephalitis and parkinsonism. might eventually
induce irreversible secondary neurological syndromes. Such effects cannot be
denied: it has been known for some years that permanent dyskinesia may occur in
patients treated with neuroleptics and drugs with neurological activity
Finally, in certain predisposed subjects: potent neuroleptics may cause actual
"malignant" syndromes with hyperthermia." (p. 163)
This is a staggering admission, but the full implications of
it still may not be clear to readers who take "dyskinesia" to refer
only to disorders of movement (although, as I have discussed, substantial
impairment in this area compromises or even destroys two fundamental dimensions
of living: free movement in space, that is, self-controlled locomotion, and
control of and feeling at home in one's own body). Deniker is actually
admitting that clinical experience with neurological diseases could have
predicted the emergence of irreversible neurological syndromes beyond simple
disorders of movement. Gualtieri and Barnhill (1988), in the course of
discussing tardive dyskinesia among mentally retarded children and adolescents
(previously treated with neuroleptics) provide the following comment concerning
the long-term consequences: "No disease that afflicts striatal tissue is
known to have only motor consequences; Parkinson's disease and Huntingdon's
disease are only two examples" (p. 150). In a later paper (1993, p. 105)
on the emergence of tardive akathisia in mentally retarded children who have
been treated (for "behaviour problems") with neuroleptics, Gualtieri
remarks "If behavioural instability and intellectual impairment are
inevitably a part of Parkinson's disease, Huntingdon's disease, and Wilson's
disease [all progressive diseases of the basal ganglia], should they not also
occur in tardive dyskinesia?" This is a rhetorical question answered in
the affirmative by his clinical research. To remove all doubt about whether
extrapyramidal symptoms observed during the 1950s should have resulted in at
least the tentative conclusion on the part of the medical community that
neuroleptics would eventually produce wide-ranging mental impairments, I can
only cite Deniker's statement that "It was found that neuroleptics could
experimentally reproduce almost all symptoms of lethargic encephalitis. .
." (p.160), along with the further statement I have already cited above.
These statements show that the clinical course and long-term consequences of
the lethargic encephalitis pandemic, which afflicted more than a million people
from 1916 to about 1930 (reviewed by Breggin, 1993), were known to Deniker and
many psychiatrists and neurologists during the 1950s when neuroleptics were
introduced into psychiatry.
The Non-Existent Dimension of "Natural
Course" in Psychiatric Thought Concerning the Costs and Benefits of Drug
Treatment
A puzzle has emerged from the preceding review of
neuroleptic-produced neuropathology and personal suffering. The puzzle is this:
How can so much iatrogenic damage be justified? This issue must hinge on the
"natural course" of schizophrenia, since on rational grounds only a
"natural course" which is more severe, chronic, and unremitting than
the consequences of the medications themselves can serve to justify serious and
wide-ranging iatrogenic damage which is itself highly prevalent and
predictable. A more complete picture of the full damage (costs) produced by
psychotropic drug treatment must also include the shift of attention away from
the psycho-social origins, development, and consolidation of the person's
psychological problems, the downplaying of psycho-social forms of treatment as
well as the diversion of funds away from such treatments, the minimisation of
current conditions of living in apprehending the person's present psychological
state, and the full range of drug-produced physical and mental impairments as
undermining the person's capacity to put to good use whatever psychotherapy or
social services might remain available. I can provide no rational answer to
this puzzle because there does not appear to be one. The drug-treatment
literature from the 1950s to the present rarely discusses the issue of
"natural course," even when the focus of the discussion is precisely
on the severity and prevalence of drug-produced neuropathology. It is simply
taken for granted as self-evident that no measures are too extreme (too risky
or costly) when it comes to treating schizophrenia. For example, even a 1982
volume of papers devoted to the subject of tardive dyskinesia, under the
editorship of a prominent biological psychiatrist (Joseph DeVeaugh-Geiss),
fails to discuss the core issue - the severity, chronicity, predictability, and
uniformity of the "condition(s)" for which neuroleptics are
prescribed. In the preface, DeVeaugh-Geiss presents the dilemma of neuroleptics
as a choice between two evils: "the disability of a chronic psychosis or
the disability of a treatment-induced movement disorder that is
untreatable" (p. vii). No further discussion is offered, which makes it
clear that DeVeaugh-Geiss takes for granted both that psychosis is chronic and
that no viable treatment possibility other than neuroleptics exists. This
inference is further supported in the lead paper (by DeVeaugh-Geiss) of the
volume, entitled "Tardive Dyskinesia: Phenomenology, Pathophysiology, and
Pharmacology." In the context of discussing other diseases of the basal
ganglia along with treatment possibilities, DeVeaugh-Geiss notes that:
"...most experts agree neuroleptic drugs should be used
to reduce movement disorder symptoms in patients with Huntingdon's disease.
Whether or not chronic neuroleptic treatment might worsen Huntingdon's disease
is unknown at this time, although the theoretical risk exists. The inevitable
progression and relatively short course of Huntingdon's disease alters the
risk/benefit ratio substantially in favour of using neuroleptics in
Huntingdon's disease, as opposed to their use in tardive dyskinesia where the
risk may far outweigh the benefit.". (1982b, p. 9)
The above summary of medical treatment considerations
crucially misses the real point, which is that neuroleptic-produced tardive
dyskinesia is an iatrogenic (medically produced) disease, not an idiopathic
(naturally occurring) disease like Huntingdon's disease, and irreversible
tardive dyskinesia is iatrogenically created in the treatment of a
"condition" which does not inevitably progress, is not uniformly or
inevitably chronic, is certainly not a "short course" affair, and may
actually improve or remit years or even decades after the patient is first
diagnosed, in the complete absence of toxic medication. My point, to reiterate,
is that what is at the core of the issue of serious iatrogenic damage - namely
the natural course of the disease - is either not discussed or summarily
characterised in a manner that is completely erroneous. Further evidence for my
contention that the natural course of schizophrenia is a non-issue in the
drug-treatment literature is provided in the same volume of papers by George
Crane (who deserves much credit for his publications of neuroleptic-produced
neuropathologies over the years). In a valuable paper on the long-term effects
of neuroleptics on the central nervous system, Crane somewhat obliquely admits
that the long-term natural course of schizophrenia is a non-issue in the
following manner:
"...The progress of schizophrenia to a defect state of
severe mental deterioration [due to long-term neuroleptic treatment) is a slow
process. It must be measured in decades rather than years. Longitudinal studies
of 20 - or 30 - years' duration have not been made on schizophrenics since
drugs were introduced in psychiatry." (1982, p. 80)
Meanwhile, evidence of mental impairments, defects,
deficits, and deterioration, as well as physical evidence of CNS pathology,
discovered in patients who have not been followed longitudinally in comparison
with same-diagnosis patients who have not been treated with neuroleptics (a
practically non-existent population in America) is now actually being advanced
as evidence that schizophrenia is a brain disease (reviewed in Breggin, 1990).
Evidence of neuropathology and/or mental impairment in diagnosed schizophrenics
has an ambiguous meaning if such patients have also been subjected to prolonged
institutionalisation and/or powerful centrally active drugs. Despite this, both
the absence of neuropathological findings in the pre-chlorpromazine era (also
reviewed in Breggin, 1990), and the tardive improvement in schizophrenics who have
not been treated with neuroleptics (based upon European longitudinal and
retrospective studies, M. Bleuler, 1978, in the former case and Ciompi and
Muller, 1976, in the latter case; see also Harding, Brooks, Ashikaga, Strauss,
and Lenderl, 1987, for a summary of the unique Vermont experiment initiated by
George Brooks in 1955) should serve to dampen enthusiasm for the current wave
of claims that schizophrenia is a brain disease.
Perhaps it has not escaped the reader's attention that,
unlike a real idiopathic neurological disease like Huntingdon's chorea, the
"natural course" of schizophrenia has been shunned in the
drug-treatment literature. There are several reasons for concluding that there
is no natural course of schizophrenia: (a) the precise criteria for
"schizophrenia" both continue to change over time and fail to
discriminate "schizophrenics" from other patients who present with
overlapping symptoms (Carson, 1991; Ciompi, 1984; Fenton, Mosher, and Matthews,
1981; Kirk and Kutchins, 1992; Mirowsky, 1990; Strauss et al., 1979); (b) the
natural course of a disease is best reserved for those diseases (like
Huntingdon's chorea) which traverse a path of inevitability and virtual
invariance in the absence of effective medical (somatic) intervention - in this
sense schizophrenia is essentially the antithesis of a disease which follows a
natural course (M. Bleuler, 1978; Ciompi and Muller, 1976; Harding et al.,
1987; Strauss, 1986; Wing, 1987; the extreme variability in course and outcome,
in fact, strongly argues against the view that schizophrenia is at root a
neuropathological disease); (c) from the point of diagnosis onward, the course
of schizophrenia is responsive to purely social-interpersonal variations in the
patient's life (an outstanding example here is Vaughn and Leff, 1976).
Non-Scientific Influences on the Development of
Psychiatry Since the Early 1950s
Since there appears to be no rational explanation for the
development in psychiatry of routine reliance (both short-term and maintenance)
on psychotropic drugs for the treatment of schizophrenia or anything else, it
is necessary to turn to considerations external to the facts of "mental
illness" and the actual properties and consequences of psychiatric drugs
in order to find a way to comprehend the beliefs and practices which have so
powerfully established themselves. It hard to see how the drawbacks and perils
of psychotropic drug treatment could have been so widely minimised were it not
for powerful shaping factors external to psychiatry. It is also hard to see how
psychiatric experience with sundry somatic treatments in the pre-chlorpromazine
era (Valenstein, 1986) could have failed to induce a more sceptical and
cautious attitude within psychiatry where it not for - again - powerful external
factors.
The external factors to which I refer are already widely
discussed outside of psychiatry. The problem is not to identify or provide
evidence for the existence and influence of such factors, but to somehow
overcome psychiatry's refusal to seriously consider their impact on theory and
practice. Frequently discussed factors include the following:
1. The fiscally determined demise of the old state mental
hospital system [Aviram et al., 1976; Brown, 1985; Estes and Harrington, 1981;
Estroff, 1981; Gronfrin, 1985; Johnson, 1990; Kiesler and Sibulkin, 1987;
Klerman, 1979; Reardon, Rifkin, Schwartz, Myerson, and Siris, 1989; Scull,
1981, 1984; Stone, 1975].
2. The growing competition (economic, ideological,
theoretical, etc.) from encroaching professions, which produced the practical
necessity to emphasise biomedical treatment possibilities (Breggin, 1991;
Cohen, 1993; Garfield, 1986; Halleck, 1971; Menn and Masher, 1982; Mosher and
Burti, 1989; Mosher and Menn, 1983; Rothblum et al., 1986; Vega and Murphy,
1990).
3. The desire to re-establish the medical (i.e., organic)
definition and understanding of all forms of psychological
distress/dysfunction/deviance [in addition to the sources listed under (2),
above, see also Coles, 1987; Klerman, 1988a, 1988b].
4. The counter-revolutionary rebound evoked by the
anti-psychiatry movement of the 1960s, and by the levelling effects on
authority and prestige resulting from multi-disciplinary "teams" in
community mental health settings [Kirk and Kutchins, 1992; Mosher and Blirti,
1989; Vega and Murphy, 1990].
5. The development of a massive financial subservience to
the pharmaceutical industry. Prominent forms of financial dependence on the
pharmaceutical industry include research grants to individual psychiatric
investigators inside and outside of the university system, unrestricted grants
to the American Psychiatric Association (APA), underwriting of APA conferences,
the provision of advertising fees to psychiatric journals, mounting and
financing public relations campaigns, gifts, and provision of honorariums and
expense money for attending industry-arranged conferences [Breggin, 1991;
Coles, 1987; Dumont, 1990; Ghodse and Kahn, 1988; Greenspoon and Hedblom, 1975;
Kessler, 1991; Preskorn, 1995; Ross, 1995; Waldron, 1977; Wortis and Stone,
1992].
6. The emergence of harsh cost-containment policies from the
commercial insurance industry, necessitated by corporate-sector demands
concerning the growing encroachment on profits caused by the cost of (employer
paid) medical insurance premiums. The evolution of more restrictive
reimbursement policies on the part of the commercial insurance industry
emphasized a narrower view of "medical necessity" and appropriate
treatment [Chodoff, 1987; Derber, 1984; Kroll and Kirsch, 1978; Kuhl, 1994;
Meyer, 1993; Navarro, 1984, Sharfstein, 1987; Wilson, 1993).
7. Budgetary redirection of mental illness - mental illness
treatment research provided by the federal government (through NIMH, NIH,
ADAMHA, etc.) as part of the overall struggle of the dominant classes to
eradicate the dangerously emancipatory concepts, sentiments, and
political-organisational thrusts which emerged during the 1960s [Cohen, 1993;
Duster, 1984; Halleck, 1971; Humphreys and Rappaport, 1993; Menn and Mosher, 1982;
Vega and Murphy, 1990; for a candid discussion of the dangerous emancipatory
thrusts of the 1960s from the perspective of political-economic elites, see
Crozier, Huntington, and Watanuki, 1975, writing on behalf of the Trilateral
Commission; Gusse and Schmacke, 1980, provide a chilling reconstruction of how
aligning with power led German psychiatry in the period leading up to the Nazi
era into ever more one-dimensional convictions concerning the biological basis
of psychological disturbance/deviance and progressively harsher views regarding
the uselessness of social-psychological forms of treatment).
These external factors produced the redefinition of
psychological distress/disturbance into more and more narrowly described
"syndromes," and promoted a psychopharmacologic nominalism designed
to provide treatment solutions to the "syndromes" classified with
drug-treatment in mind. By "nominalism" I mean the practice of
creating a name for something mainly on the basis of self-interest rather than
on the basis of evidence. What is most real about psychiatric drugs is their
toxic and impairing properties, which psychiatry either elides under the guise
of side effects or fails to recognise at all. The distinctions made within
psychiatry between drugs (anti-anxiety, antidepressant, etc.) are largely
self-serving fictions. The great transformation involved in shifting from
promoting certain drugs as unusually potent "tranquillisers" to
promoting the same drugs as "antipsychotics" is an illustration of
nominalism. This transformation has been carried off with the aid of turning a
blind eye toward the intricacies of assessing placebo possibilities and to the
complexities of distinguishing between impairment and clinical benefits (e.g.,
failing to press clinical observers into differentiating between drug-produced
decrements in disturbing hallucinations vs. drug-produced apathy and muting of
mental life generally). Reports in the psychiatric literature that reveal
psychopharmacologic classification as nominalism are simply ignored; for
example:
1. In a summary paper reviewing ten years of clinical
psychiatric experience with depot fluphenazines, Frank J. Ayd, Jr. (1975), a
well-known drug treatment advocate, cautions that high-dose therapy should be
reserved for patients who "are still reacting [on more customary doses]
with affect to their delusions and hallucinations rather than accepting them
complacently" (p. 494) - clearly the expected reaction. This does not
prevent Ayd later on the same page from referring to depot fluphenazines as
"effective antipsychotic agents," although the context seems to make
it clear that the drug-effect is far more accurately described as "apathy
producing" rather than "antipsychotic."
2. Lerner et al. (1979) report their surprise at discovering
that high doses of diazepam (Valium) and haloperidol (Haldol) were not
differentially effective in symptom reduction. Each treatment resulted in
highly significant improvement. They interpreted their results very cautiously,
that is, they did not bring into question whether tranquillisers and
antipsychotics are really different.
3. In an extensive review of psychiatric literature
concerning neuroleptic treatment for psychosis, Keck, Jr. et al. (1989)
attempted to integrate what could be learned about the time course of patient
response to antipsychotic medication. Only five studies out of 1300 citations
yielded adequate time course data. The interesting finding is that
antipsychotic medication was no more effective than placebo, diazepam, or opium
powder. The authors discuss their results cautiously, but acknowledge that
"Perhaps the early effects [up to four weeks, actually, based upon the
data they examined] of antipsychotic drugs are non-specific and are largely the
same as those of sedative agents. The success of placebo treatments suggests
that early improvements may be largely due to the non-specific effects of
hospitalisation or other clinical interventions apart from the specific
therapeutic effects of prescribed pharmacologic agents"(p.1291).
4. The effects of neuroleptics on people who have not been
given a psychotic diagnosis and who presumably are not mentally ill are
apparently the same as on psychiatric patients who have been given a diagnosis
of psychosis. Non-psychotic groups include children in residential facilities
for the mentally retarded, children in non-residential schools for the mentally
retarded, adults in nursing homes and old-age homes, non-psychiatric medical
patients, and normal volunteers. Belmaker and Wald (1977) provide an
interesting report concerning their own experience with a single 5-mg
intravenous dose of haloperidol. Based upon this experience, these psychiatric
researchers were moved to suggest that "neuroleptics may function to
restrict cognitive and emotional processes in normals as well as
schizophrenics, and thus it is possible that [a neuroleptic] does not
specifically antagonise schizophrenic pathology" (pp. 222-223).
The above citations are just the tip of the iceberg. The
issue, to repeat, is whether psychiatric classification of psychopharmacologic
drugs (antipsychotics, etc.) represents anything more than a self-serving
nominalism.
An unusually revealing summary statement concerning the
modern effort to refine diagnosis in light of developments in pharmacologic
treatment which directly bears on nominalism is provided by one of the elite
architects of the new biopsychiatry, Gerald Klerman (1988a) .In this instance
Klerman's remarks were offered in the context of introducing papers presented
at an international conference on anxiety disorders which took place in
Bavaria. Klerman begins his summary by acknowledging that scientific
psychiatry's "great leap forward," the DSM-III, has abandoned the
traditional psychotic-neurotic dichotomy, as well as unproven conclusions that
much psychopathology represented complex lines of development/adaptation to
decidedly unfavourable conditions in family life or even more broadly
considered social circumstances.
What replaced the pre-DSM-III nosology (Klerman explains) is
a new, empirically derived but non-theoretical schema based upon "vigour
presenting symptoms" and corresponding categorisation, such as
"anxiety disorders" (p. ix). But this official
"neo-Kraepelinism" dissolves on the very next page, where Klerman
reveals that the new (DSM-III) disorders and categories are actually based upon
psychopharmacologic treatment and the presumption of "genetically
determined abnormality of CNS chemistry as the predisposition." In
addition (p. x), the entire issue of nosology as embodied in the DSM-III is by
no means simply a matter of scientific controversy, since it strikes at the
heart of interprofessional conflicts between M.D. psychiatrists and Ph.D.
psychologists. Interestingly enough, the very first paper in the anthology of
papers introduced by Klerman (Wittchen, 1988) reveals that it is completely
untenable - as in counterfactual - to split-off anxiety from depression: people
who are anxious, have panic attacks, are agoraphobic with or without panic
attacks, have "simple" phobias, or are obsessive-compulsive (assessed
by the Diagnostic Interview Schedule and/or clinical ratings based upon DSM-III
criteria), are also highly likely to reveal depressive signs and symptoms. It
would seem that only the prior commitment to a class of
"antidepressant" drugs and a class of "antianxiety" drugs
makes it necessary to diagnostically separate "anxiety disorders"
from "affective disorders," in addition to the presumption (which
cannot be empirically supported) that what is actually wrong with the patient
is the emotional-cognitive-behavioural consequences of a "genetically
determined abnormality of CNS chemistry." In short, all the old burdens of
psychological understanding are wiped away by the expedient of a strictly
medical reconstruction of illness and treatment. It also should not he
overlooked that such a deconstruction of the person from a unified
psycho-social totality into a potential aggregate of narrowly defined syndromes
has the consequence of creating a purely fictional theoretical and diagnostic
dilemma for (contemporary) psychiatry, namely the vexing issue of co-morbidity.
It is difficult to find support within psychiatry for the
discrete syndrome or disorder classification scheme advanced in the DSM-III
series and the DSM-IV, even among the architects of the DSMs (Brown, 1987;
Frances et al., 1991; Kendell, 1988; Strauss et al., 1979; Terr, 1991; Widiger
and Shea, 1991). In practice, clinical signs (impulsivity, delusional thought,
etc.) and symptoms (hallucinations, attacks of intense anxiety, dissociative
phenomena, etc.) wander across many supposedly discrete syndromes or disorders.
No one appears to seriously maintain that any syndrome or disorder presents a
distinctive and discrete physiognomy. The continued reassertion of the category
system is based upon non-scientific considerations which are nonetheless of
great importance to the profession of psychiatry: identification with organic
medicine; public relations; billing and reimbursement procedures to and from public
and private third party providers; institutional record keeping and budgetary
planning; research grant applications and awards from government, private
foundations, pharmaceutical companies, etc.; disability and compensation
hearings from many sources; multifaceted forensic activities; facilitating the
actuarial and epidemiologic calculations of the insurance industry, upon which
premium rate-settings are established and costs can be estimated so that a high
profit margin is maintained; ideological control of "mental illness"
as primarily a problem that fits into conventional medicine, and so forth.
Unfortunately, rank and file practitioners across the mental health professions
devote much time and effort to teaching and learning how to use the DSMs to identify
what the patient "really has." Since everyone in the field must
digest and use the DSMs, a very serious impediment to meaningful thought
results.
It is now widely acknowledged in the psychiatric literature
that the prevalence, seriousness, and variety of neuroleptic-produced side
effects is incompatible with continued enthusiasm for using neuroleptics in
clinical treatment, This acknowledgement should not be confused, however, with
actual prescription practices on the part of psychiatrists. Nor does it lead to
renewed interest in social-interpersonal approaches to treatment, or with
lessened faith in the organic aetiology and pathogenesis of mental illness, or
a more cautious attitude toward the long-term consequences of neurotoxic drugs.
It also does not produce a more critical interest in how the private
industry-FDA-psychiatric research complex operates to make new drugs available
for treatment. In short, the catastrophe of medically-created disease of
unprecedented proportion has not produced a critical self-examination on the
part of psychiatry as to the ideological, conceptual, financial, and systemic
components which in combination produced the catastrophe. I will illustrate
this by discussing the introduction of two contemporary drugs into psychiatry,
alprazolam (Xanax) and fluoxetine (Prozac).
Learning Nothing From the Past - The
Introduction of Xanax and Prozac into Psychiatry
Introduction to the
Upjohn Sponsored Studies Resulting in FDA Approval of Alprazolam as a Panic
Disorder Treatment
Although it defies all ordinary understanding of bias and
conflict of interest, pharmaceutical companies in America are completely in
charge of the studies upon which the FDA grants a new drug approval. Congress
has considered the possibility of constructing a less flawed method than
allowing the sponsoring company itself to design the clinical trials and to
select and pay investigators (Braithwaite, 1984), but the logic of U.S.
capitalism seems to preclude modifying this arrangement. Successful marketing
of a new psychiatric drug depends upon reaching and influencing the only group
legally empowered to make the drug directly available to the public, namely
physicians. Direct marketing approaches to physicians consist mainly of
frequent visits by pharmaceutical "detail" men and women, and (for
psychiatric drugs, specifically) the highly sophisticated and expensive ads
which appear in psychiatric journals. The journals of course purport to publish
disinterested scientific reports, but at the same time both the journals
themselves and a substantial percentage of the reports published in them are in
fact financially supported by the commercial pharmaceutical industry. Just what
the prevailing arrangement means in practice is well illustrated by the Upjohn
initiated, sponsored, and controlled clinical studies which resulted in FDA
approval for alprazolam as a specific treatment for panic disorder.
The clinical studies which served as the basis of FDA
approval for Upjohn's alprazolam as a specific treatment for panic disorder
were reported in the Archives of General Psychiatry, Volume 45, May 1988. The
introductory overview to the studies is provided by Gerald Klerman, former
director of NIMH and ADAMHA. As Breggin (1991) points out, Klerman is quite coy
about revealing his link to Upjohn. The reader finds Klerman identified on the
bottom of the first page of his article (1988b, p. 407), in the usual space, as
associated with the Department of Psychiatry, Cornell University Medical
School. But in the body of the paper, under the heading "steering
committees of investigators," Klerman reveals that the entire
multi-centre, cross-national research project - which he describes as "one
of the largest controlled clinical trials in psychiatry" (p. 407) -was
under the direction of James H. Coleman of Upjohn's Psychopharmacology Research
Unit and one "G.L.K." - himself, of course. At this point the
sophisticated reader who has spotted this single, abbreviated, reference to
Klerman as actually one of the two people in charge of the entire research
project (along with an employee of Upjohn) will also suspect that such a large
role for such a prominent person involves a large fee. The text that Klerman
provides leaves it entirely up to the reader to guess what the actual financial
arrangement might be. According to a telephone interview with Klerman that
Breggin summarised in Toxic Psychiatry, Klerman admitted to an
"ongoing" relationship with Upjohn since 1982 or 1983, and that he
was "hired specifically to help develop the overall package of Xanax
studies for FDA approval" (quoted in Breggin, 1991, p. 349).
As Braithwaite (1984) points out, it is certainly possible
to imagine an arrangement in which the federal government acts as an
intermediary between the sponsoring pharmaceutical company and the clinical
investigators. The basic idea would be to sever the direct money-for-services
connection between the sponsor and the researchers, as well as severing the
development of a long-term, mutually beneficial relationship between
pharmaceutical company and allegedly disinterested scientific investigators. As
matters stand, the FDA is in the position of relying entirely upon data
generated under the direct control of a commercial enterprise single-mindedly
fixated on profits (Kessler, Rose, Temple, Schapiro, and Griffin, 1994). The
"expert panels" which the FDA may constitute in order to further
evaluate the clinical studies directed by the sponsor are themselves composed
of researchers accustomed to working for the industry (Pam, 1990). The fact
that the Upjohn studies I discuss here resulted in FDA approval should make it
clear that the prevailing arrangement is incompatible with public health and
safety.
At the conclusion of Klerman's overview, following the
reference section, an "Editorial Note" appears in small print from
the Editor of the Archives of General Psychiatry, Daniel X. Freedman (on p.
412). The note advises the reader not to be concerned about the fact that he is
both the journal's Editor (who decides upon which articles will be accepted for
publication) and a consultant to the Upjohn Company for this very study, for
which Upjohn paid in order to get FDA approval of its own product. Presumably
the reader understands that consultant means a financial arrangement between
the Editor and the Upjohn Company. Although Freedman assures the reader that
all is well, he does not see fit to explain why the research papers could not
have simply been submitted to another journal, a journal whose Editor was not
being paid by Upjohn to get FDA approval for alprazolam.
Following Klerman's overview paper, all three subsequent
papers which report on different aspects of the alprazolam research acknowledge
the sponsorship of the Upjohn Company; the last paper in the series - on
discontinuation effects - even lists Carl P. Lewis, M.D., Ph.D., as one of the
authors. Lewis is identified as part of Upjohn's Psychopharmacology Research
Unit. Klerman admits in his overview that the steering committee (Klerman and
J.H. Coleman of Upjohn's Psychopharmacology Research Unit) " ...met
frequently to review the protocol, to make amendments as required, to monitor
the progress of the study, and to plan for data analysis and for scientific
presentation and publication" (1988b, p. 409). This last admission
presumably accounts for the overall finding of safety and efficacy, despite the
actual data and various important methodological shortcomings (as discussed in
part in the long letter to the Editor by Isaac M. Marks and ten other prominent
international workers in the field of anxiety disorders). Breggin reports that
Marks personally told him that the letter was at first rejected by Archives
editor Freedman, its publication was delayed for a year so that its impact was
diminished, and finally that Freedman deleted important portions of the letter
without permission when he did finally allow its publication (p. 351 of
Breggin, 1991; the Marks et al. letter appeared in Archives of General
Psychiatry in 1989, 14 months after the Upjohn sponsored studies were
published). The entire project, although sponsored by Upjohn for its own
private gain, made extensive and free use of publicly funded academics, medical
schools, hospitals, and so forth. This is an illustration of how private,
for-profit corporations get costs financed by public funds.
The effect of industry-controlled publications on the
integrity of medical journals is lamented by M.N.G. Dukes, Head of The
Netherlands' Ministry of Health, Department of Pharmacotherapy, on the occasion
of the 1979 Kyoto International Conference Against Drug-Induced Suffering:
"...for every one impartial and serious report from a
physician recording his observations consciously and in a useful manner there
are in the literature some 10 or 20 papers of merely promotional character,
written, it is true, by physicians, but commonly ghost-edited and sponsored by
the promotional departments of drug companies and published largely (but not
exclusively) in second-rank journals. ...One must regard this form of pseudoscientific
drug promotion, involving misuse of the medical literature, as one of the bad
habits into which the industry has got itself entangled. . . ." (1980, p.
180)
The reader can decide whether these Upjohn initiated,
sponsored, designed, and controlled studies constitute "pseudoscientific
drug promotion" and a "misuse of the medical literature." The
point Dukes makes about pseudoscientific drug promotions being ghost-edited
should be modified somewhat for the American scene in psychiatry, where it
hardly seems worth the effort to disguise the financial arrangements between
drug company and physician.
In the examination of the Upjohn-FDA approval studies which
follows I intend as far as possible to stay within the framework of thought
advanced by the studies themselves. What I intend to show is that these studies
are not merely beset with errors of reasoning and methodology; rather, I wish
the reader to consider that these studies are not actually concerned with
conducting a sophisticated investigation informed by forty years of clinical
research and clinical practice experience with psychotropic drugs. I propose
instead that the most sensible and parsimonious way to interpret these studies
is to keep in mind what their overall purpose is and the derivative need to put
the best face possible on a bad situation, namely treating psychological
distress with a sedating, toxic, highly addictive, and dangerous drug. In other
words, I will not attempt to ignore the details of the studies by dismissing
the whole project out of hand on the grounds that it is absurd to treat
psychological distress as a chronic, unremitting, idiopathic somatic disorder
like epilepsy or diabetes. In fact, the insistence that panic disorder is an
unremitting idiopathic illness turns out to be precisely the justification for
the otherwise incomprehensible trivialisation of the problems inherent in
prolonged drug treatment, namely side effects (including non-neurological
conditions like hepatitis), tolerance, addiction, withdrawal effects, and
rebound effects. Since the principal investigators take it for granted (see
ahead) that drug treatment is the only viable option for this "chronic,
unremitting illness," there is presumably no reason to clarify that
rebound and withdrawal effects may operate to produce distress/symptoms despite
continuing to take the medication regularly (Ashton, 1991). The
"facts" of "mental illness" are used to maximise the
professional position of psychiatry and the profits of the pharmaceutical
industry. But at the same time it is important to be aware of just what
considerations are completely outside of the project and framework of thought
which these studies embody.
1. The assertion that what is being treated with alprazolam
(Xanax) is in reality an idiopathic neurophysiological disorder relegates the
patient's actual history of loss, threat, abuse, etc. to irrelevance, and
likewise moves the patient's present social-interpersonal circumstances into
irrelevance. In a 1978 publication, Klerman made it clear that the resurgent
neo-Kraepelinian movement held as an axiom that psychiatric disorders were to
be regarded as fundamentally organic in terms of etiopathogenesis. At that time
he was unable to cite any functional psychiatric disorder which had been shown
to even be regularly associated with a demonstrable pathophysiology, much less
organic aetiology. In his 1988 overview of the Upjohn sponsored Xanax studies,
he was still obliged to admit that no actual evidence of pathophysiology
existed in the case of people diagnosed with panic disorder or agoraphobia.
2. The entire issue of what the impact of the psychiatrist's
disinterest in the patient's history or present social-interpersonal
circumstances might be in the long run has no opportunity to emerge as a
clinical dimension. As is customary in psychiatric clinical drug studies, all
contact with the patients/subjects is terminated quickly. In these Upjohn
sponsored Xanax studies all contact with the patients/subjects ended after 14
weeks.
3. It follows from point one that from a treatment point of
view the idea is abandoned that the individual must somehow use the therapist's
supportive/interested stance to come to grips with past and present pathogenic
influences in order to construct a better life. This is evident from the simple
fact that alprazolam treatment is advanced in the same spirit as insulin
treatment for diabetes. In short, issues concerning self-alienation and
personality defect, which any serious clinical interest will invariably bring
into the light, are eclipsed by the task of chemically subduing narrowly
described symptoms.
4. Any notions that psychological distress is a sign of past
or present disturbing conditions in terms of interpersonal life situations, or
that psychological distress in the present has the teleological function of
signalling to the social-surround that untoward events are occurring, are
likewise abandoned.
5. The complexity of the individual's life from a
multifaceted psychosocial functioning perspective is reduced to target symptoms
and global self-reports. In short, the problem of assessing the person's
psychological status (at any point in time) is treated with the same delicacy
as a Gallup poll on U.S. foreign policy. Just what can emerge when the patient
is allowed/encouraged to talk is a primary issue for all research efforts which
are concerned with persons as complex psycho-social beings (Kleinman, 1988;
Mies, 1983; Mishler et al., 1981; Rubin, 1976; Sennett and Cobb, 1972; Warren,
1988).
6. The inevitable passing of control of affective life from
personality resources, interpersonal relations and social circumstances, to the
closed circle of drug effects (intended and side), tolerance, addiction,
withdrawal, and rebound is conceptually elided, as are the implications of this
for the individual's future.
7. The crucial insight that over time the individual may
accommodate/ habituate to drug-produced sedation and other forms of
mental-behavioural impairment, so that strictly from the perspective of patient
complaints a false appearance of relative well-being may he presented, is
outside the realm of assessment-evaluation in these studies.
Examination of Klerman's
"Overview" of the Upjohn Alprazolam Studies
With the above caveats or reminders in place, I will begin
anew with Klerman's overview, with the intention of exposing errors of
reasoning, methodological and conceptual problems, and disregard for what is
actually known about the dangers of psychotropic drug treatment. Klerman, to
recall, is providing a rationale for and summary of the results of the entire
project in his overview.
Experimental design. Klerman
begins his description by noting that the project compared an 8 week trial of
alprazolam against placebo. In their critique letter, Marks et al. (1989)
question the point of an 8 week treatment trial in a sample whose mean symptom
duration was almost 9 years. This objection requires expansion. First,
psychotropic drug research experience over the past forty years has made it
abundantly clear that it is thoroughly misleading to compare a biologically
active drug with an inert placebo. An intellectually honest study would have
included an active placebo group (i.e., a drug which produces subjective
effects - like dry mouth - but is not believed to be psychoactive, so as to
provide a means of assessing the possible contribution of psychosomatic placebo
effects to overall clinical improvement) and another psychotropic drug
treatment group. There is simply no other way to ascertain what comparative
clinical benefits and costs are produced by the psychopharmacologic action per
se of the trial drug in question. It should be noted that in 1991 - that is,
after alprazolam was approved by the FDA as a specific treatment for panic
disorder - Russel Noyes, Jr., one of the senior researchers in the overall
project, reported (Noyes, Garvey, Cook, and Suelzer, 1991) in the context of a
further discontinuation study that after an 8 month treatment trial alprazolam
and diazepam were not significantly different on two outcome measures of
treatment for panic disorder. In fact, On the "mean panic attacks per
week" measure diazepam was superior to alprazolam at the .06 level of
significance. In all relevant respects diazepam turned out to be the more
useful and less dangerous drug, but Noyes and associates did not draw the
obvious conclusions from their own data, perhaps because this was another
Upjohn financed study. Meanwhile in 1988[b] Klerman can only say that
"conventional benzodiazepines have been thought to be ineffective against
panic disorder" (p. 408). It remains obvious that it is pointless to
compare alprazolam alone to an inert placebo.
Second, an 8 week trial is absurdly short because no one,
especially the researchers who designed and conducted the study, intends for
alprazolam to be used for only 8 weeks, and therefore the side effects,
discontinuance emergent effects, and rebound produced by its expected much
longer-term clinical use cannot be ascertained in what is, after all, the one
and only FDA trial conducted. Following FDA approval no further trials or
evidence are required, and no regulations are placed upon the drug's clinical
use (the commercial importance of this point is brought out by Kessler, Rose,
Temple, Schapiro, and Griffin, 1994; note that David A. Kessler is the Head of
the FDA). In their reply to the Marks et al. letter, Klerman and the other
senior investigators attempt to answer the criticism that alprazolam's
purported advantage over placebo during a 4 week period (that is, the period in
the 8 week study before the high placebo group drop-out rate made data analysis
controversial) is clinically insignificant by admitting that the common pattern
for psychopharmacologic treatment is to continue medication for a much longer
period, so as to avoid immediate relapse. In fact (1989, same journal) Klerman
et al. acknowledge that the actual expected period of use is quite prolonged,
even indefinite, given tile "chronic nature of the illness" (p. 672).
But in making this admission they simultaneously reveal just how medically
irresponsible it is to seek FDA approval based upon an 8-week study.
Third, the absurdly short time frame of the trial does not
even provide for an opportunity to determine whether the drug under
investigation will sustain an advantage against inert placebo over the course
of a clinically more realistic period of time. In fact it is only by blatant
data reanalysis that alprazolam appears to produce a clinical advantage against
inert placebo over the 8-week trial period (see ahead for more details). A 1992
clinical trial com- paring alprazolam to inert placebo over a 32 week period
found no advantage for alprazolam compared to placebo in terms of panic attack
frequency and the Hamilton Anxiety Scale (Dager et al., 1992).
Disregard for neurotoxic
effects.
Under "background" (1988b, pp. 407-408), Klerman refers to
"recent research" (no citations) which demonstrated the importance of
the gamma-aminobutyric acid (GABA)-benzodiazepine receptor complex in mediating
clinical effects. He also states that in 1982 the Upjohn Company initiated
research on alprazolam for the purpose of seeking FDA approval. Here two
references are cited. One reference turns out to be a 1986 study concerning
alprazolam by Leibowitz, Fyer and others. Klerman's reference to the
GABA-benzodiazepine receptor complex in all likelihood takes for granted that
the journal's readership is largely uninformed concerning the details of
neuroanatomy, neurochemistry, neurotransmission, pharmacology, and
neuropathology. The limited literature that exists on the prescribing behaviour
of psychiatrists (e.g., Seidenberg, 1971; Turner, 1971; Waldron, 1977)
indicates that drug advertisements in psychiatric journals are far more
determinative for prescribing behaviour than the scientific articles that
appear in the same journals. This turns out to be even a more serious issue
than meets the eye, since information supplied in the Physicians Desk Reference
(PDR), upon which physicians heavily depend, is little more than paid drug
advertisements limited only by the feeble influence of the FDA (Johnson, 1980;
Waldron, 1977; Wortis and Stone, 1992). Since psychiatric drug advertisements
in journals are not all that different than information provided in the PDR or
drug inserts supplied by the manufacturer, the only recourse a conscientious
practising psychiatrist has is to actually read the voluminous scientific
literature concerning controlled studies. But this is heavily influenced in
turn by pharmaceutical industry sponsors, research grants, and the like.
Finally, even drug studies that are not compromised directly by financial ties
to the drug industry take for granted the project of chemically subduing
narrowly defined symptoms, along with the other conceptual-methodological forms
of tunnel vision I have described.
Klerman either is not concerned with or does not expect the
readership at large to grasp that it is completely unrealistic to assume that a
drug which is physiologically active in the "GABA-benzodiazepine receptor
complex" will only be active in this (hypothetical) complex rather than
widely active in numerous neurotransmission systems (such as the
dopamine-GABA-acetylcholine system). Although much is written in
biopsychiatrically oriented and psychopharmacologic drug treatment literature
about advances in understanding the brain, the truth is that from a practical
perspective (that is, from the perspective of deliberate intervention in brain
physiology) the total integrated system of neuroanatomy, neurotransmission, and
homeostasis- equilibrium mechanisms is still in what could accurately be called
the explorative-speculative stage of knowledge (Heinrichs, 1993; Post, 1992;
Stuss and Benson, 1986). Therefore, deliberate interventions in CNS functioning
must be regarded as heroic medical practice, a step that can only be justified
in the face of demonstrable and serious neuropathology, and in the absence of
less risky treatment alternatives. As to the former condition, Klerman himself
admits that" ...there is no direct evidence of abnormal biochemistry
findings for diazepam receptors in patients with normal or clinical states of
anxiety. ..whether or not there are any abnormalities in the [benzodiazepine
receptor] complex or in endogenous substances that might interact with the receptor
complex during normal anxiety or during clinical states, such as panic disorder
and agoraphobia remains uncertain" (p. 411). As for the latter condition,
Klerman confesses that the" ...scientific issues [of diagnosis and
treatment] are further confounded by professional tensions: most behaviour
therapists are Ph.D. psychologists, while most of the proponents of
psychopharmacology are M.D. psychiatrists" (1-1. 408).
Just how little concern Klerman has about deliberate
interventions in CNS functioning -in the absence, to reiterate, of demonstrable
abnormality or pathology -is revealed by the fact that his citation section,
although it includes Liebowitz, Fyer et al., 1986, does not draw upon Fyer,
Liebowitz et al.'s 1987 alprazolam discontinuation study. In the course of
discussing the serious discontinuation (withdrawal) problems encountered in
this study, Fyer, Liebowitz et al. draw upon a colleague's speculations as to
just how alprazolam use may act to disrupt neurophysiology:
Klein has proposed a possible explanation of the rapid panic
recurrence and withdrawal symptoms observed during alprazolam discontinuation
(personal communication). He speculated that alprazolam exerts its antipanic
effect by blocking afferent pathways to the locus ceruleus or other
noradrenergic centres. Massive differentiation usually produces receptor
hypersensitivity distal to the point of blockage. In this case, discontinuing
alprazolam treatment would be expected to leave these hypothetical
noradrenergic receptors hypersensitive and prone to over-response. (p. 307)
The general neural mechanism being calmly discussed above -
hypersensitivity - is precisely the mechanism most often advanced in the
psychiatric literature for tardive dyskinesia and other late appearing disorders
which result from prolonged dopamine receptor blockade caused by neuroleptic
drug treatment. The neurological diseases so produced may be irreversible and
untreatable (this is the case with non-transitory tardive dyskinesia, and
probably other neuroleptic-produced tardive disorders like tardive akathisia,
e.g., Gualtieri, 1993). Fyer, Liebowitz et al., in their own paper, appear
completely unconcerned about the implications of alprazolam-produced receptor
hypersensitivity. Their only comment is that a quick-acting alpha-two agonist
such as clonidine might somewhat ameliorate withdrawal symptoms. The first page
of this scientific paper, published in the American Journal of Psychiatry,
dutifully reports that the research was financed in part by the Upjohn Company.
Klerman, who is surely aware of Upjohn sponsored alprazolam research, does not
even bother to mention the danger that Fyer, Liebowitz et al. casually dismiss.
Needless to say, the design of an 8-week study for FDA approval completely
avoids the danger of late-appearing neuropathology. But, of course, as the
senior authors admit in their rejoinder to the Marks et al. letter, it is taken
for granted that in actual clinical practice alprazolam treatment will be
prolonged or indefinite.
The creation of
"panic disorder" in DSM-III for Upjohn's alprazolam. Under the
major heading "Design of the Cross-national Collaborative Panic
Study" (beginning on p. 408), Klerman (1988b) continues to provide
"deep back- ground" on the origins and reasons for the cross-national
collaborative panic study. Based upon a December 1982 scientific conference on
anxiety held in Key Biscayne, Florida, he explains, it was decided to proceed
with a series of multicentre clinical trials. Upjohn paid for these
multicenter-clinical trials, but Klerman does not inform the reader either who
sponsored the Key Biscayne conference or who decided to proceed with the
multicenter clinical trials for alprazolam. Klerman's expository style makes no
distinctions between Upjohn's commercial interests and the scientific problems
and projects facing psychiatry. Evidently there is no difference, if I
correctly under- stand the information Klerman provides in this section. That
is, the statement that the decision to initiate multicenter alprazolam trials
necessitated refinements in diagnosis is followed directly by explaining that a
special version of the Structured Clinical Interview (SCID) developed by
Sptizer and Williams for DSM-III diagnosis was created for Upjohn's alprazolam
trials (the SCID-UP). Further,
"The DSM-Ill classification was modified. and three
categories of panic disorder were identified for the research on alprazolam:
(1) Panic Disorder Uncomplicated (DSM-III Panic Disorder), (2) Panic Disorder
with Limited Phobic Avoidance, and (3) Panic Disorder with Extensive Phobic
Avoidance (DSM-III "Agoraphobia with Panic Disorder")". (1988b,
p. 408)
Since Klerman specifically states that "Spitzer and
Williams had already started to develop a Structured Clinical Interview (SCID)
for DSM-III diagnosis, and a special version (SCID-UP) was developed on anxiety
disorders" (p. 408), and since DSM-III was published in 1980, the
conclusion seems inescapable that the DSM-III panic disorder categories were
created for the purpose of Upjohn's alprazolam clinical trials for FDA approval
as a specific treatment for panic disorder. Thus it would seem that Klerman has
solid historical and factual reasons for drawing no distinctions between
Upjohn's commercial interests and the professional-scientific concerns of
psychiatry as they are embodied in the DSM-III.
Disregard for
methodological refinements suggested in prior studies and for prior findings of
alprazolam-produced EEG abnormalities. Although Klerman
describes both phase one of the alprazolam trial (alprazolam versus placebo)
and phase two of the alprazolam trial (comparing alprazolam, imipramine, and
placebo) under "design" (p. 408), only the useless comparison between
alprazolam and placebo served as the basis for FDA approval of alprazolam as a specific
treatment for panic disorder. As I discussed earlier, only direct comparison of
alprazolam with other benzodiazepines. other classes of psychotropic drugs, a
biologically active but not psychotropic placebo, and an inert placebo could
provide the necessary minimal conditions for generating useful discriminative
information about alprazolam. It is also puzzling why these studies alone
served as the basis of FDA approval, since they certainly are not the only
studies which used alprazolam for the treatment of panic. A much longer
treatment and discontinuance alprazolam-panic study reported in 1987 (Fyer et
al., a study partly financed by Upjohn) showed very substantial withdrawal
effects, relapse, and rebound. In addition, the Fyer et al. study clearly
recognised that its discontinuation data had to be regarded as suspect because
of failure to obtain compliance checks (plasma benzodiazepine drug screens) for
10 or 17 subjects. Yet the official Upjohn-FDA approval study repeated the same
error. A study published in 1992 which did include such a check found that 23
of 44 alprazolam patients tested positive at the conclusion of the taper (i.e.,
no authorised alprazolam) versus zero of 17 placebo controls (Dager et al.,
1992). The official discontinuance study (Pecknold, Swinson, Kuch, and Lewis,
1988) does not even acknowledge that failure to check compliance with the
protocol taper schedule (via plasma screens) is a crucial methodological error.
Fyer et al. (1987), directly following their admission that the lack of a
compliance check might have substantially compromised the validity of their
findings (which were very negative for alprazolam), conclude that it is
necessary to directly compare tapering on alprazolam with other drugs,
variations in the rate of alprazolam decrease, and the use of adjunctive
medication to aid in the (pervasive and serious) consequences of alprazolam
withdrawal "before alprazolam's therapeutic role can be fully
assessed" (p. 309). None of these necessary steps was taken in the alprazolam-FDA
studies. Fyer et al. also report that weekly EEG recordings were completed on
10 of their 17 discontinuance subjects. Of these, two had excessive slowing on
one EEG examination. The authors do not state that this is a sign of
neuropathology, which it is, nor do they discuss the matter. It is impossible
(for me, at least) to tell from their write-up which patients presented this
sign and at which point in time - other than the fact that the abnormal EEG
readings were obtained at some point in time beyond the planned 30-day taper
period, since 13 of the 17 subjects could not endure the planned taper schedule
(this includes the two subjects who gave an abnormal EEG reading). It is clear
from the text that no long-term neurological follow-ups were conducted. Despite
abnormal EEG readings in 2 of 10 alprazolam-treated patients in a
pre-"official" Upjohn sponsored FDA-approval study, the
"official" discontinuance study (Pecknold et al., 1988) conducted no
neurological examinations of any kind. As I have already discussed, these FDA
approval-seeking studies simply ignored the organic consequences of long-term
alprazolam treatment, although Marks et al. (1989) point out in their critical
letter that a literature already existed suggesting ventricular enlargement in
patients who were long-term benzodiazepine users.
In spite of clear indications of serious withdrawal effects
and/or use-effects (above), Klerman's (1988b) overview of the total project's
design (phase one followed by phase two) reveals that -"assuming there
would be no problems of safety" (p. 408) - the second phase began in the
summer of 1984, although the clinical part of phase one was not even completed
until 1985. Since Upjohn employees and paid consultants were in charge of every
aspect of this study, it would seem that there was no reason to actually wait
for phase one results to emerge before it was deemed safe to go on to phase
two.
The Upjohn Sponsored Studies Which Resulted in
FDA Approval
I turn now to details of the Upjohn studies themselves as
they are presented in three separate papers: efficacy in short-term treatment,
patient acceptance, side effects and safety, and discontinuation effects.
Efficacy in short-term
treatment
(Ballenger et al., 1988). Since this efficacy study compared alprazolam to an
inert placebo, it is crucial to clarify just why this experimental design
cannot adequately address the issue at hand, which is to assess the clinical
benefit(s) produced by the psychopharmacologic action of the drug itself, that
is, separated from or unconfounded by other possible contributions to clinical
improvement. If this is not accomplished, then there is no way to evaluate just
what the clinical costs of the drug are in comparison to its benefits (if there
are any benefits over and above other possible sources of contribution to
clinical improvement). In psychotropic drug trials, experience (that is,
clinical research experience with psychiatric drugs over the past forty years
or so) suggests the following sources of (perceived) clinical improvement may
be at work in the drug trial:
(a) the clinical benefits produced by the
psychopharmacologic activity of the drug itself, acting alone (i.e., aspirin
should relieve headache even if the person does not know what the substance is
and what it is supposed to accomplish, or even if the person does not realise
that medicine has been ingested).
(b) the drug giving-taking interaction, in terms of its
psychological impact on the patient (this is the most commonly discussed
"placebo" effect).
(c) the biological activities of the drug which are
subjectively noticed by the patient but which are not considered part of the
pharmacological activity relevant to clinical gain (sedation, ataxia, etc.).
Such side effects of the drug may nevertheless instigate a psychosomatic source
of clinical improvement (i.e., a further placebo effect).
(d) the psychological consequences for the patient of being
"in treatment" with impressive authorities, in an impressive setting,
etc., along with the concerned, interested attention and support of the entire
treatment team (i.e., a further placebo effect. A dramatic illustration of just
how potent such sources of clinical improvement can be for psychiatric patients
was published by Raskis and Smart in 1957; this source of con- founding in
psychiatric drug trials is hardly a new idea).
(e) the misperception of clinical improvement (on the part
of clinical observers and/or
the patients themselves) based upon what are conceived of as
unwanted effects of the drug, e.g., mistaking the consequences of drug-produced
sedation and amnesia for reduction in panic intensity, frequency, concern, and
so on (Fink, 1974, despite being a prominent advocate of electroconvulsive
shock treatment, discusses a variety of psychological assessment techniques
which all support his own conclusion that the clinical improvement produced by
ECT is based upon brain damage and the "euphoric-anosognosic"
reactions of some patients to damage. Anosognosia is a term derived from
clinical neurology which refers to unawareness of injury or impairment. Breggin
(1991) has used Fink's research as part of his own conclusion that the apparent
benefits of psychiatric drugs are all based upon damage and impairment. Despite
Fink being an ECT advocate, his work shows just how crucial it is to include
enough variety of assessment methods to judge whether the observed or reported
improvement is not more realistically understood as impairment).
With the above list of possible contributions to (perceived)
clinical improvement in mind, it is readily apparent that the design of the
alprazolam-panic studies (alprazolam versus placebo) cannot produce any data at
all which expose sources (c), (d) and (e), above. In short, the possible
contributions to clinical improvement observed in the experimental group
(alprazolam) and control group (lactose filler) which may derive from sources
(c), (d) and (e) [the latter pertains only to the alprazolam group] remain
completely unknown. Thus the degrees of safety and efficacy - upon which FDA
approval is supposed to rest - likewise remain unknown at the conclusion of
this "controlled" drug trial. I wish to emphasise that my analysis of
possible confounding sources of (perceived) clinical improvement in this sort
of drug trial is hardly based upon knowledge which I uniquely possess.
By the expository technique of separating efficacy from
unwanted or adverse side effects (each examined in separate articles), the
clinical benefits derived from alprazolam treatment are presented as if they
were cost-free. Despite the frequently repeated conclusion by Ballenger et al.
that alprazolam treatment is rapidly effective and safe, the actual data
themselves tell a different story. The most consistent and important finding of
this study - the authors' own commentary to the contrary - is the rapid rate of
improvement of the placebo group. Even during the first four weeks of treatment
(before the high placebo-group drop-out rate began), where statistically
significant differences favour alprazolam over placebo, it is nevertheless the
case that the magnitude of difference is small and what remains most striking
is the degree to which the placebo group has improved relative to baseline
(especially in view of an average duration of illness of approximately 9
years). By week 8 (again, a very short time period), examining the data that
actually exist rather than the imaginary data (see ahead) that Ballenger et al.
advance as most important, there are practically no benefits from alprazolam compared
to placebo: no significant difference between the two groups in total panic
attacks per week, spontaneous panic attacks per week, situational panic attacks
per week (Table 2, p. 416); percent of patients panic free (neither type
present), percent of patients free from situational panic attacks (Table 3, p.
416); mean ratings of disability in work, in social and leisure time, and in
family and home (Table 6, p. 418).
The placebo group's improvement is actually the most
important finding of this study since (a) it 'indicates that whatever it is the
subjects suffer from can be modified in a clinically beneficial direction
without recourse to a highly addictive drug with unknown but suspect long-term
consequences, and (b) it indicates that largely unknown and unexamined
social-interpersonal aspects of the total research study situation exert potent
effects that operate in the direction of clinical gains. Since these purely
social-interpersonal sources of clinical gains operated in the absence of any formal
psychotherapy arrangement (which the research design strictly prohibited), the
most responsible conclusion (scientifically and medically) should have been to
channel future efforts in the direction of refining treatment techniques that
do not require drugs. Of course, as Klerman admitted in the overview, such a
conclusion directly implicates professional tensions between M.D. psychiatrists
and other treatment professions, in addition to the self-evident point that
Upjohn is hardly amenable to the conclusion that drugs are unnecessary for
treatment. These studies are for the purpose, after all, of obtaining FDA
approval for Upjohn's alprazolam. As a general observation, I can state that
placebo effects are consistently strong and effective, and this fact -as well
as what it implies about the putative organic basis of "mental
disorders" - is systematically elided in the psychiatric literature, which
almost uniformly regards placebo effects as an annoyance in the task of
demonstrating the efficacy of the drug at hand (Kleinman, 1988; Ross, 1995).
Just to cite one important example, the efficacy and promise of
"placebo" effects should have been, but of course was not, the major
conclusion of the 1964 NIMH collaborative research study regarding phenothiazine
treatment in acute schizophrenia, based upon how much the placebo group
improved in the absence of any attempt to provide psychological treatment or to
upgrade the social conditions of life in-hospital.
Placebo effects are potent and ubiquitous in medicine (Dinnerstein,
Lowenthal, and Blitz, 1966; Kleinman, 1988; Ross, 1995), Since psychiatric
drugs are toxic in clinical dosages (whatever additional clinical benefits may
also be produced), their clinical use demands a methodologically sound
demonstration that no extant non-drug treatment can provide substantial
clinical benefits (the Upjohn alprazolam studies of course did not include any
non-drug treatment other than placebo).
I have already suggested that a broad reading of the
psychiatric drug treatment research literature reveals that (inactive!) placebo
effects are consistent and strong, A clever confirmation of this conclusion in
the area of antidepressant medication has recently been provided by Greenberg,
Bornstein, Greenberg, and Fisher (1992), Their demonstration depends upon the
reanalysis of drug studies which, at the time they were conducted, used both an
inactive placebo group and an established antidepressant medication group
(imipramine or amitriptyline) to establish by comparison the clinical advantage
of a newer antidepressant drug (amoxapine, maprotiline, or trazadone),
Greenberg et al, reasoned as follows: (a) the attempt to provide support for a
new antidepressant drug (the point of the research effort) indicated lessened
vested interest in the other medication on the part of the researchers, (b) the
use of an older antidepressant medication and a newer antidepressant drug in
the same study made it more difficult for the researchers to recognise who was
on which drug or placebo (i.e. to penetrate the double blind research design),
(c) using only patient self-ratings for the reanalysis rather than researcher
interview methods of assessment (i.e. the Hamilton Rating Scale for Depression)
further deprived the researchers of an opportunity to penetrate the double
blind on the basis of familiar side effects described by patients during the
course of the interview, In short, studies which used both an inactive placebo
group and a standard antidepressant medication group for the purpose of showing
the clinical advantage of a new drug provided the opportunity to re-evaluate
the effectiveness of standard antidepressants versus placebo when the vested
interest (Greenberg et al's term) had moved on to some new drug, The reanalysis
of such data revealed that patient ratings concerning the antidepressant effect
of the standard antidepressant medications were no different than for the inert
placebos,
A major issue for analysing the results of the 8 week trial
comparing alprazolam to placebo was that only 56% of placebo patients who
completed the first three weeks of the trial remained in the study by week 8,
Ballenger et al "solve" this problem by using the data obtained on
the placebo subjects at the end of week 3 and who subsequently dropped out in
place of the non-existent data for weeks 4, 5, 6, 7, and 8:
"As has become the standard method in such situations,
we also analysed the "end point data" from all evaluated patients,
using the week eight data when they were present and the last available value
carried forward when they were not" (p.416)
In other words, 44% of the data for week 8, in what the
authors called the end point analysis, actually were not obtained during week 8
but sometime before week 8, since from week 3 to week eight 44% of the placebo
group dropped out of the study. It is this end point data - 44% of which are
simply imaginary - that Ballenger et al. repeatedly urge the reader to regard
as the real findings of the study. The reader has no way of knowing until and
unless the Marks et al. letter is examined, which was published more than a
year later, that the research subjects were told that they could drop out of
the study and receive alternative active treatment (1989, p. 668) if they
wished. Marks et al. further reveal in the letter that, according to a personal
communication from R.P Swinson, M.D. at the Toronto site (May 10, 1988),
research personnel who were retrospectively asked to guess which patients were
on placebo and which on alprazolam were 90% correct. Marks et al. therefore
conjecture that prescribers and raters who were not actually blind may have
encouraged dropouts. This is a quite different conjecture about the high drop
out rate than the one proposed by Ballenger et al., who suggest the high
placebo drop out rate was produced by the ineffectiveness of the (inert)
placebo. Ballenger et al. also do not recognise that symptom relief based upon
sedation and mental impairment (the alprazolam group) does not have the same
meaning and significance as symptom relief in the absence of sedation and
mental impairment (the placebo group, see ahead).
The proposal on the part of Ballenger et al. that the high
placebo group attrition rate shows the ineffectiveness of placebo effects
requires further consideration. What is ultimately at stake here from the
perspective of practical treatment possibilities is the idea that many people
who suffer panic attacks will not benefit from non-pharmacologic treatment
(although it is equally clear that many will benefit, and the authors do not
seem interested in how to make the relevant discrimination). Of course the
placebo group was not receiving any specific treatment, but it is nevertheless
useful for drug proponents to show that the social-psychological aspects of
placebo treatment provide little benefits. There is actually a very compelling
additional explanation for the high placebo group drop out rate (that is, in
addition to prescribers and raters not being blind as to which subjects were
receiving placebo in conjunction with subjects being informed that they could
drop out and receive "alternative active treatment"). The additional
compelling explanation for the high placebo group attrition amounts to this: a
substantial but not precisely determinable proportion of the placebo group was
with drawing from one or more benzodiazepines (Xanax and/or Valium) during the
course of the 8 week study. This completely changes the understanding of the
drop out rate: from the "ineffectiveness" of placebo to intolerance
of benzodiazepine withdrawal.
The evidence for the alternative explanation is provided by
the researchers, although they fail to apply the information to the issue of
placebo group attrition. To begin with, subjects were accepted for the study
despite being on "psychoactive medication" (p. 414). Following
acceptance to the study, subjects were instructed to discontinue psychoactive
medication for a 7-day period. This instruction therefore initiated a
convoluted issue of who did and did not comply and the consequences (for understanding
what happened to the placebo group) of compliance and non-compliance. Following
the initial drug-free week, a second drug-free week was designated as the
pre-treatment, baseline week. The same convoluted issue of
compliance-non-compliance pertains here. As a biochemical check of compliance,
plasma measures of alprazolam (Xanax), diazepam (Valium), and desmethyldiazepam
(the principal metabolite of diazepam) were obtained during the baseline week,
and again during weeks 3 and 8. During what was supposed to be the second
successive drug-free week (the baseline week), 25% of the placebo group had
measurable plasma levels of a benzodiazepine (1.6% measurable plasma levels of
alprazolam plus 23.4% measurable plasma levels of desmethyldiazepam). Even at
week 8, of the placebo group subjects who remained in the placebo group, 12.3%
had measurable plasma levels of a benzodiazepine (all the foregoing figures
come from Table 7, p. 419). The upshot is that the placebo group was actually a
mixture of people withdrawing from benzodiazepines, those surreptitiously
taking a benzodiazepine, and those not previously on a benzodiazepine and who
complied with the protocol. It is not known "who was who," but it is
clear that some placebo subjects were withdrawing from a benzodiazepine during
the 8 week study period, and it is clear that the placebo group as a whole
emerged as an unknown mixture of different treatments.
Patient acceptance, side
effects, and safety (Noyes et al., 1988) .The question of whether a
drug can be used safely as medication is obviously a core component of what the
FDA is supposed to evaluate. The issue facing the FDA was not whether
alprazolam should or should not be made available for physicians to prescribe,
since alprazolam was already an approved medication. The issue rather was
whether or not the agency should extend its imprimatur to alprazolam as a
specific treatment for panic disorder. The FDA realised that approval would
result both in enhanced credibility for the disorder itself, a diagnostic
entity which owed its existence in large measure to Upjohn's efforts, and in a
massive upsurge in Xanax (alprazolam) prescribing. (1)
Upjohn's own researchers in this matter, namely Noyes et al.
(1988), repeatedly state that high doses of alprazolam produced few side
effects, but Marks et al. (1989) point out in their critical letter that
"the data suggest otherwise" (p. 619). The manner in which Noyes et
al. compare frequency of adverse effects in the alprazolam group to frequency
of adverse effects in the placebo group is misleading, since it gives the
impression that the pharmacologically inert placebo (lactose filler) produced
much the same "side effect profile" as high doses of alprazolam. A
more realistic treatment concerning the side effects of lactose filler for this
placebo group would address both temporal variations in the original symptom
complex (fatigue, etc.), and the commonplace. drug study phenomenon that the
placebo group tends to mimic the active drug treatment group in terms of nature
and time course of side effects (Fisher and Greenberg, 1993, discuss the latter
point in terms of "penetrability" of the standard "double
blind" arrangement).
In addition, Noyes et al. do not consider the possibility
that reduction in reporting some adverse effects on the part of the alprazolam
group over the 8 week active drug treatment period may be due to the
development of lessened self-awareness and self-monitoring, which are common
consequences of neurological injury (Dinnerstein, Lowenthal, and Blitz, 1996;
Lindstrom, 1977; Morrow, Ryan, Hodgson, and Robin, 1990; Streufort and Gengo,
1993; Stuss and Benson, 1986; Summerfield, 1978). It is necessary to
investigate whether some symptom reduction due to the clinical use of a
neurotoxic agent is part of a larger clinical picture of neurological morbidity
as Fink (1974) has done, that is, to apply multiple assessment methods which
challenge a broad spectrum of cognitive-perceptual capacities. Nothing of this
nature was attempted by Noyes et al. As I have pointed out previously, it is
characteristic of psychiatric clinical drug studies to simply ignore the
complexity of psychological life.
Noyes et al. report that "only" 10 of the 263
alprazolam treated patients (about 4%) developed "serious or
unexpected" reactions. Three subjects became severely intoxicated on only
l or 2 mg of drug. One subject became "completely amnestic" for a 2
day interval on 6 mg daily. Aggressive or violent behaviour was reported by one
subject on 4 mg daily; although this subject had not, according to the authors,
behaved in this manner before receiving alprazolam, he was retrospectively
judged to have an unstable personality disorder. Two subjects became manic,
although neither had a history of mania. Two subjects developed alprazolam-produced
hepatitis. Noyes et al. do not explain how such reactions - produced at a rate
of about 4 in 100 - are compatible with consistently describing alprazolam as
"safe." They also do not discuss the fact that in actual clinical practice
it is not likely that most patients will meet once a week (as in the research
study) with a psychiatrist for the purpose of carefully reviewing
alprazolam-produced reactions. Although the authors note that "[symptom
checklist] items reflecting cognitive impairment were more often reported by
subjects taking alprazolam" (p. 425), and also that "the effects of
benzodiazepines on memory are well known" (p. 427), they do not appear to
consider this cognitive impairment a serious side effect, nor do they consider
its effects on total psycho-social functioning. As previously discussed, this
series of studies does not consider the organic and mental/behavioural
consequences of long-term drug use at all, although long-term use is exactly
what is expected in terms of treatment.
Discontinuation effects (Pecknold, Swinson, Kuch, and Lewis,
1988). The most glaringly irresponsible aspect of these Upjohn sponsored
research reports is the manner in which the topic of discontinuation is
handled. Although the Ballenger et al. (1988) paper reports on "efficacy
in short-term treatment" (8 weeks), short-term treatment is not the
expected use for alprazolam in the treatment of panic disorder. Klerman and the
other senior investigators make this point clear in their 1989 response to the
Marks et al. (1989) critical letter in Archives of General Psychiatry. In the
response to Marks et al. they admit that it is in fact expected that alprazolam
will be used in the treatment of panic disorder "indefinitely," due
to the "chronic nature of the illness" (p. 672). In short, the
discontinuation data derived on the basis of 8 weeks use is simply a sham,
since the investigators are perfectly well aware that this time period does not
represent how alprazolam will be used in clinical practice.
It should not be imagined that benzodiazepine addiction
(alprazolam is a benzodiazepine, like Valium and Halcion) is merely an
inconvenience. The major danger is that acute psychological and physical
adverse effects may accrue over time, evolving into a tortured and severely
impaired existence for the chronic user. Attempts to reduce the dosage or to
discontinue completely may not be an option due to the severity of rebound and
withdrawal reactions (Ashton, 1984, 1986, 1987, 1991). Although the present
group of subjects (for the Pecknold et al. discontinuation study) reported a
long history of panic attacks, no evidence is presented which suggests that the
emergence of panic episodes necessarily or usually heralds chronicity. Even
when episodes of panic do become chronic, alprazolam (all benzodiazepines)
causes too many severe adverse effects to be used as a long-term treatment. I
have already observed that the placebo group improved substantially over the 8
week period of placebo-taking in spite of the fact that no deliberate form of
treatment for this group was permitted by the research design. In a subsequent
investigation instigated by these Upjohn-FDA approval studies, Marks et al.
{1993) have shown that a psychological form of treatment can achieve clinically
beneficial results without exposing patients to adverse drug effects and
addiction. Note that by 1988 the State regulatory body in Britain, the
Committee on the Safety of Medicines, had taken the step of officially warning
all doctors that benzodiazepines should only be used on a short-term basis
{Committee on the Safety of Medicines, 1988; Gabe, 1994). By contrast, in 1989
Klerman et al. acknowledge that they expect alprazolam to be used
"indefinitely" in the treatment of panic disorder. It cannot be overlooked
in this regard that in Britain a large part of the entire organisation of
medicine is removed from private capital accumulation by virtue of the National
Health Service.
On the basis of internal FDA documents obtained through use
of the Freedom of Information Act, I can state that the FDA was so concerned
about adverse long-term effects and addiction that it took the unprecedented
step of extracting a commitment from Upjohn to conduct post-marketing,
long-term dose-response and withdrawal studies by 1992 {letter from Robert
Temple, M.D., of the Office of Drug Evaluation 1, to J.R. Assenzo, Ph.D.,
Upjohn Company, dated November 6, 1990). In the letter from Dr. Temple, Dr.
Assenzo is reminded that Upjohn is required to comply under FDA regulations
concerning a New Drug Approval. In response to my specific inquiry to the FDA
concerning these required studies by Upjohn, I received a letter {dated June
15, 1995) which simply stated that the FDA has no documents "responsive to
your request."
With regard to the Pecknold et al. {1988) study, the results
following 8 weeks of alprazolam treatment or placebo by 4 weeks of taper and
then 2 further weeks of no drug or placebo are discussed under three headings:
relapse, rebound, and withdrawal syndrome.
Relapse data can be summarised straightforwardly. The
alprazolam patients swiftly relapsed while the placebo group continued to
improve during the taper period and the post-taper period or held more or less
steady during this period {depending on the symptom or measure). The authors
attempt to minimise the significance of the relapse data by pointing out that
by the end of week 2 of the post-taper period the alprazolam patients who were
still left in the discontinuation study had more or less achieved parity with
the placebo group. But it isn't too difficult for the careful reader to discern
how misleading it is to present the last post-taper week data in such a manner,
for by this point only 33 alprazolam treatment patients out of the original 59
who began the taper were still left in the study, the rest having fled back to
alprazolam because they could not endure the combined consequences of relapse,
rebound, and withdrawal {note again that the placebo group did not relapse, nor
did it suffer drug-produced rebound effects and other drug-discontinuation
effects, that is, withdrawal syndrome). It is also necessary to once again
recall that no plasma screenings were conducted to check on compliance during
taper and post-taper, so that it is legitimate to be sceptical about the extent
to which the alprazolam patients who had not officially given up the attempt to
withdraw actually complied with the protocol. As mentioned above in connection
with Klerman's overview paper, a 1992 study (Dager et al.) which did conduct
plasma checks on compliance found evidence of non-compliance in 23 of 44
alprazolam-treated patients.
The rebound effects for the alprazolam group are striking:
of the 16 patients who were identified as suffering rebound panic, 4 reported
more than 50 panic attacks per week during their worst week, and 8 reported
from 6 to 36 attacks per week. This contrasts to the group's (N=59) baseline
average number of panic attacks per week of 6.61 (Table 1, p. 432). Of the 8
alprazolam patients identified as suffering rebound anxiety, 3 had scores on
the HAM-A exceeding 40 points (the baseline average for the alprazolam treated
group was 23.86). Since rebound scores can only be obtained for patients who
continue on taper or later on zero dose post-taper, patients who terminated
discontinuation and relieved their withdrawal suffering by taking alprazolam
could not be counted in terms of rebound. Inspection of week by week numbers in
the alprazolam group during discontinuation (Table 1, p. 432) supports this
interpretation. If this is correct, then patients who could not tolerate
discontinuation did not figure into the data on rebound (this would mean that
26 of 59 patients in the alprazolam group did not figure into the rebound data
by the second post-taper week). Again, no plasma level check was conducted to
ensure that the rest had actually tapered to zero and remained at zero during
the two post-taper weeks.
Pecknold et al. begin their report on "the withdrawal
syndrome" by stating that no serious or life-threatening symptoms were
observed, that in no case was the withdrawal syndrome incapacitating, and that
of the 21 patients (of 59 who originally began withdrawal) in the alprazolam
group identified as suffering withdrawal symptoms, symptoms were considered minimal
for 8, mild for 7, moderate for 6, and severe for none. Withdrawal symptoms
included confusion, clouded sensorium, heightened sensory perception, dysosmia
(abnormality in taste and smell), paresthesias (tingling), muscle cramps,
muscle twitch, blurred vision, diarrhoea, decreased appetite, and weight loss.
The authors admit that the experimenter-created checklist limits what counts as
a withdrawal symptom, and that the experimenter-created demand that subjects
report at least four simultaneous symptoms in any given week to qualify as
suffering from withdrawal syndrome may have operated to underestimate the true
prevalence of withdrawal syndrome. There is no recognition or discussion of the
fact that the alprazolam group's rapid flight back to alprazolam-taking
obviously results in underestimation of the withdrawal syndrome. The importance
of the limited checklist is borne out in a later discontinuation study by Noyes
et al. (1991), who found that "Perhaps the most distinctive [withdrawal
symptoms] were the unusual or distorted perceptions reported. ...These included
a feeling of movement when there was none and the perception that body parts
had become separated from the rest of the body. Also reported were sensations
of floating and falling, shimmering vision, and faulty depth perception"
(p. 522). Of course by the 1991 report FDA approval was not at issue, as it was
in Pecknold et al.'s 1988 presentation of findings (recall that Noyes is the
first author of the 1988 report in this series on side effects and safety).
Although Pecknold et al. state that no patient suffered a
severe withdrawal reaction, no information is actually provided as to how
withdrawal syndromes were differentiated into minimal, mild, moderate, or
severe. Likewise, no method of evaluation is presented as the basis of the
conclusion that no patient was "incapacitated," or even just what the
authors mean by this term. This conclusion is all the more suspect because the
authors insist on discussing relapse, rebound, and withdrawal separately, as if
these discontinuation phenomena were not happening simultaneously to the same
person. Recall that 4 of the "non-incapacitated" subjects suffered
more than 50 panic attacks during their worst discontinuation week.
Since the placebo group is not actually withdrawing from
anything, the comparison of the placebo group's withdrawal symptoms with the
alprazolam group's withdrawal symptoms does more to obscure than to enlighten
the consequences of discontinuation for the alprazolam group. The experimental
design could have included somewhat different time lines for taper and
discontinuation within the total pool of alprazolam patients. In this manner
dose-reduction and discontinuation-emergent effects could have been more
credibly observed, eliminating at one stroke the confusing issue of symptom
overlap with the placebo group. Given the seriousness of rebound and withdrawal
effects for patient well-being (the two terms actually refer to the same
physiological process), it is difficult to think of a higher priority for
obtaining valid data in the overall research design. This is all the more
pressing because regular daily use of alprazolam does not obviate
rebound/withdrawal effects, since the biological activity of the drug initiates
compensatory physiological reactions which result in such effects as the drug
is metabolised (Ashton, 1991),
Prozac -A Further
Illustration of Psychiatric Irresponsibility, Commitment to Invasive Medical
Treatment, and the "Safety" Provided By the FDA
Many of the themes I have discussed above are also well
illustrated in a recent clinical report concerning fluoxetine (Prozac)-produced
akathisia (Lipinski, Mallya, Zimmerman, and Pope, 1989). Since financial
support for this study was supplied by public funds (U.S. Public Health Service
grants from NIMH), the obligation to act responsibly in the public interest is
all the more pressing, although licensed physicians should not require
additional incentive to act responsibly in the public interest, as the only
justification for restrictive legislation on the part of the state (i.e.,
licensing) is the public interest (certainly not the interests of the
profession or the pharmaceutical industry).
It is clear from details provided in the text that Lipinski
et al. had been supplied with fluoxetine by Lilly Laboratories and were using
it clinically on the basis of FDA permission (for "compassionate
use") for some time before FDA approval of fluoxetine as a treatment for
depression was granted in 1988. It therefore seems self-evident that it was
incumbent on the authors to bring their clinical observations of
fluoxetine-produced akathisia to the attention of the FDA before fluoxetine
received FDA approval, but there is no suggestion that this was done or even
attempted in the report, which was not even submitted for publication to the
Journal of Clinical Psychiatry until July 6, 1988. This obligation was all the
more pressing since, as reported on page 340, the authors had no expectation
(based obviously upon information provided by the manufacturer, Lilly
Laboratories) that fluoxetine would produce akathisia and therefore did not
even look for this adverse effect until it was recognised by a psychiatric
nurse (one of the eventual authors, Paula Zimmerman, R.N.). Apparently the drug
insert information for fluoxetine as of the submission date of the paper (July
6, 1988, six months after fluoxetine had been marketed as an FDA approved
antidepressant) still provided no information concerning its
akathisia-producing properties. Based upon their own clinical assessments of
fluoxetine-produced akathisia on 20 patients, the authors estimate that the
prevalence rate for fluoxetine-produced akathisia is from 9.8% to 25%. However,
they immediately add that "only a properly designed prospective study with
adequate numbers of subjects can answer this question" (p. 340). But, of
course, Lipinski et al. fail to suggest that fluoxetine should not have been
approved for marketing while the prevalence rate was unknown, nor do they suggest
that fluoxetine should not be used widely (as it was and is) while its
akathisia-producing prevalence rate remains unknown. The authors are apparently
content to allow the true prevalence rate to emerge slowly on the basis of
clinical reports seeping into the literature over years or decades. Meanwhile,
this adverse effect is treated with a variety of ameliorative drugs (e.g.,
propranolol and/or a benzodiazepine), and with no concern for long-term
neurological damage and irreversible tardive neuropathologies (tardive
dyskinesia seems especially likely, given fluoxetine's effects on dopamine
neurotransmission). Lipinski et al.'s briefly stated observation that patients
who developed akathisia due to fluoxetine "suffered greatly" (p. 340)
is unusual in the psychiatric literature, although it in no way influences
their thoughts about its continued use.
The notion of compassionate use of a non-FDA approved drug
has a special meaning within the medical-pharmaceutical-FDA network. The FDA
has the authority to permit non-approved drugs to be used by physicians if the
FDA can be persuaded that evidence exists which suggests possible patient
benefit - thus compassionate use. In the present case it can be seen how the
commitment on the part of psychiatry to drug treatment converges with the
interest of pharmaceutical companies in marketing profitable new drugs. Both
interests lead to a specific outcome, namely clinical trials with experimental
drugs on human subjects. It is by no means clear to me how experimental drugs
should be tested on humans under the best of conditions. It is clear that under
prevailing conditions the pharmaceutical industry and the psychiatric
profession need to be constantly testing new drugs. There is little incentive
to realistically think-through what informed consent is supposed to mean to
people who agree to take experimental drugs. Under extant legal authority the
FDA cannot even oblige pharmaceutical companies to divulge all they really know
about an experimental drug's effects on laboratory animals, on the grounds
(according to the pharmaceutical industry) that such disclosure would required
surrendering "trade secrets" (Dukes, 1980; Johnson, 1980). Since
nothing prevents the federal government from granting the FDA such authority,
the limitations imposed upon the FDA's ability to protect the public suggests
that its real (as opposed to nominal) purpose is to protect and advance the
pecuniary aims of the industry it is supposed to regulate (Berman, 1978;
Navarro, 1976). I do not wish to move my critique of scientific psychiatry too
far afield, but it is simply impossible to advance an intelligent discussion of
psychiatric drugs without bringing in drugs as business and the relation of
business to government. This does make the topic more complicated, but ignoring
these complications has a high cost - to scholars of course, but more
importantly to people who wind up taking the drugs.
It should be emphasized that reports concerning adverse
effects of psychopharmacologic treatment seep very slowly into the psychiatric
literature. Major problems exist in the area of psychiatric undereducation
concerning the existence and recognition of adverse effects and in the area of
clinical non-recognition or mis-diagnosis of adverse effects (Dixon, Weiden,
Frances, and Rapkin, 1989; Van Putten and Marder, 1987; Weiden, Mann, Haas,
Mattson, and Frances, 1987). The upshot is that psychiatric opinion regarding
the range and prevalence of a drug's adverse effects must be regarded with
great scepticism. Dixon et al. (1989) report that their examination of the
curricula of five local psychiatric residency programs revealed that on average
only 0.5 hours was spent specifically on neuroleptic-produced neurological
syndromes during the course of the entire program. Brown and Funk (1986)
provide an important discussion of medical reluctance to recognise iatrogenic
illness.
Lipinski et al., present five clinical cases for the purpose
of illustrating the phenomenology and time course of fluoxetine-produced
akathisia. These five cases are described as representative (1989, p. 340), and
indeed they are, not merely of fluoxetine-produced akathisia, but of the entire
tragedy of treating psychological distress "in a strictly medical
sense."
It will suffice to summarise and comment upon only two of
the cases:
Case one. Miss A was
hospitalised at the Mailman Research Centre, McLean Hospital, when she was 18
years old. She is described by the authors as "well" until the
"onset of typical depressive symptoms" 18 months earlier. She is
further described as developing severe obsessions, including fear of
contamination and compulsive rituals, approximately six months after the onset
of depression. Since the authors had clearly met Miss A for the first time when
she entered McLean Hospital, the question arises as to how they knew she was
well until the onset of typical depressive symptoms 18 months earlier. If such
a retrospective judgement can be plausibly made, it would have to depend upon a
great deal of information, much of which could only come in the form of
self-disclosure from the client herself. The authors present no basis for their
description of the client prior to her appearance at McLean Hospital. There is
certainly nothing in their report which suggests that their description was
based upon a prolonged and in-depth exploration of the patient's life from her
own point of view. The reader is certainly curious as to what events,
conditions, or circumstances might have contributed to the sudden emergence of
Miss A's depression, but Lipinski et al.'s write-up does not address this.
It might be argued, I believe disingenuously, that the
report is essentially an adverse-drug reaction notification, and therefore not
the place to discuss the origin of Miss A's outbreak of symptoms. Such an
argument would entirely miss the point of describing Miss A as well until the
outbreak of symptoms when she was approximately 16~years old, since this
characterisation simply dismisses as irrelevant the vast psychiatric clinical
research literature which indicates that it is preposterous to expect the
emergence of such serious symptomatology in someone who in reality enjoyed a
benign course of psychological development (e.g., Bryer, Nelson, Miller, and
Krol, 1987; Fontana, 1985; Goodwin, 1985; Gunderson and Chu, 1993; Pribor and
Dinwiddie, 1992; Rose, Peabody, and Stratigeas, 1991; Terr. 1991). The
description of Miss A as well up to the recent past is a deliberate advancement
of biopsychiatric theory, which, as Klerman (1978) made explicit in anticipation
of the DSM-III, regards psychological development as irrelevant to both
diagnosis and etiopathogenesis. In short, Lipinski et al.'s credulity regarding
Miss A's psychological history represents the paradigm shift within
psychiatry's ruling elites during the past 25 years - from the psycho-social
framework of thought to the biopsychiatry-neo-Kraepelinian framework of thought
(Wilson, 1993). It is the self-confident (if largely tacit) reliance on the
latter framework which spares Lipinski et al. any need to justify
"treating" Miss A with what is manifestly a neurotoxic chemical
substance, or to comment on the fact that during the past 18 months she had
been already treated with alprazolam, amitriptyline, lithium, perphenazine, and
pimozide.
If any thought was given to the possibility that Miss A
might first and above all need her treatment professionals to seriously inquire
into the conditions of living which prevailed at the time of her outbreak, or
that she might improve with proper psycho-social care, or that her
psychological condition in the present might be hopelessly confounded by drug
interaction effects, side effects, and withdrawal effects, it certainly does
not appear in the summary of her case. Instead, Miss A was at once treated at
McLean with a non-FDA approved drug about which little was known. On treatment
day 5 she reported severe anxiety and displayed typical signs of akathisia.
Since she was being treated in a research centre, fluoxetine was not
discontinued. Rather, a beta-adrenergic receptor antagonist (propranolol) was
added to her drug regimen to ameliorate her fluoxetine-produced akathisia.
If the treatment 'professionals at McLean had any concern
that adding another centrally active drug to what had already shown itself to
be a neurotoxic substance (fluoxetine) might further disrupt Miss A's
neurophysiology - especially in the long-run -it likewise failed to appear in
the write-up. It cannot be overemphasised that the long-term consequences of
fluoxetine in combination with propanol are unknown. Psychiatric drug research
simply does not address itself in any planned (prospective or retrospective)
manner to the issue of long-term consequences (e.g., Crane, 1982). Reports in
the psychiatric literature on adverse consequences are not based upon long-term
follow-up studies -such studies do not exist. Nevertheless, it can be surmised
from other sources that long-term exposure to neurotoxic chemicals leads
eventually to serious organic and psychological morbidity (Lindstrom, 1977; Morrow,
Ryan, Hodgson, and Robin, 1990; Streufort and Gengo, 1993; Summerfield, 1978).
Recall that Miss A was only 16 and a half when she began to be exposed to
neurotoxic "medications." Psychiatric drug research and clinical
practice seems -incredibly -indifferent to the long-term consequences of
centrally active drugs.
Case four. Ms. D is a
35 year old woman with a five year history of progressively worsening Obsessive
Compulsive Disorder "refractory to treatment with several antidepressants
and ECT" (Lipinski et al., 1989, p. 340). At admission to McLean, she was
receiving trazodone 600 mg/day. She also displayed mild jerking movements in
all extremities, diagnosed as myoclonus. This reveals that her CNS had already
been damaged, a state of affairs Lipinski et al. are willing to attribute to
her history of exposure to several antidepressants and to ECT. It is therefore
obvious that the long-range outlook for Ms. D must emphasise protecting her
from further CNS assault. Nevertheless, three days after discontinuation with
trazodone she was placed on 20 mg/day of fluoxetine. Within 12 hours she
developed signs of akathisia - an unmistakable sign of neurological
disturbance. Furthermore, her myoclonic symptoms had become more severe.
Treatment with 60 mg/day of propranolol (another centrally active drug)
produced remission of symptoms of akathisia, but the myoclonic symptoms
continued. Lipinski et al. do not reveal how they could discern that the
subjective symptoms of akathisia (anxiety, tension, restlessness, agitation)
had remitted while the symptoms of Obsessive Compulsive Disorder and
depression, which overlap to a substantial degree, still required treatments
with fluoxetine. In the general discussion section, the authors admit that
akathisia persisted for more than a year in the case of one patient
(unidentified), but they do not explain how this might be compatible with
overall clinical gain produced by treatment with fluoxetine.
The entire tone of this report takes it for granted that
psychological symptomatology indicates in-hospital treatment with an
experimental neurotoxic agent. In this regard it is necessary to point out that
most of the money spent on "mental health treatment episodes" in this
country is for in-patient treatment (approximately 82%, according to Kiesler
and Simpkins, 1993), and that reimbursement policies on the part of both the
federal government and the commercial insurance industry actively discourage
out-patient care (Brown, 1985; Kiesler, 1992; Kiesler and Sibulkin, 1987). This
means that - contrary to what Kiesler and Sibulkin (1987) regard as popular
opinion, even among many mental health professionals - psychiatry as a
profession is tied to the medical hospital setting, regardless of how
counterproductive it is to treat psychological disturbance as a medical
condition which requires hospitalisation and conventional medical treatment
(drugs).
Perhaps the most poignant spokesperson on the issue of using
drugs as treatment is Loren Mosher, former NIMH Chief of the Centre for Studies
of Schizophrenia and founder of the Soteria House project in San Jose,
California, a non-hospital, primarily non-drug facility for the treatment of
persons newly diagnosed as schizophrenic. Despite the well-documented success
of this project over a ten year period, funding by NIMH and other sources was
ultimately terminated. Mosher has been remarkably candid concerning the reasons
for the demise of the Soteria project, namely its manifest threat to the
hospital-psychiatry-pharmaceutical industry (an excellent and brief summary of
treatment findings regarding the Soteria project as well as non-scientific and
non-treatment reasons for its demise is provided by Mosher and Menn, 1983).
Certainly the vigorous promotion of biopsychiatry (both in terms of cause of
psychological disturbance and in terms of treatment of psychological
disturbance) drains interest, energy, and resources away from practical
responses to the roots and manifestations of psychological damage. In terms of
the origins and development of psychological disturbance, what is most
important is to limit the individual's exposure to pathogenic conditions of
life. Since treatment professionals have little to gain by prevention, minimal
professional thought is devoted to this area (Kleinman, 1988). Thus psychiatry,
like American medicine generally, is fixated upon diagnosis and treatment
(Hurowitz, 1993). Unfortunately, medical treatment for the already sick remains
problematic in all areas of medicine, but perhaps nowhere more conspicuously
than in psychiatry. In terms of treatment, it is first of all imperative to
acknowledge that by the time a person has become a "patient," a good
deal of damage has already been done. Practically speaking, this means that
conditions of healing must be made available for prolonged periods if there is
to be a realistic hope of substantial and sustained improvement. Although it is
appealing to suppose that the means (i.e., psychotropic drugs and/or ECT) exist
to apply a purely technological relief from psychological disturbance, I hope
that 1 have provided reasons for concluding that this does not in fact
constitute a viable route for healing or even palliation.
Conclusions
In the preceding pages I have discussed the following points
concerning the past forty years of psychiatry's attempt to treat psychological
distress in a strictly medical sense:
1. Psychopharmacologic treatment research has in effect
created a fabulous beast - a person who is simultaneously better or improved
under one heading of a research report and suffering from \V hat may be
disastrous side effects under another heading of the same report. The way is
prepared for this purely rhetorical outcome by construing the seamless totality
of the patient's psychological distress/disturbance/dysfunction in terms of
narrowly defined target symptoms, and thereby creating a problem and task that
fits into a medical framework of thought and action. In this manner the
consequences of the "medicine" in terms of its effect on the target
symptoms can he regarded as independent from its other consequences, and the
idea that the patient is an actual person whose life-as-a-whole is completely
integrated as a unified totality is dispensed with. It is only by defining
target symptoms narrowly that it is conceivable even to discuss the relative
efficacy of psychopharmacology and psychotherapy, since the psychiatrically
reconstructed task is indifferent to how the target symptoms are subdued, the
suffering and disability produced by adverse drug effects, and the long-term
(unexamined) organic and psychological consequences of treatment with centrally
active chemicals.
2. The reconstructed task of pharmacologically subduing
narrowly defined target symptoms operates to render irrelevant both the
patient's past (in terms of conditions of life and resultant course of
psychological development); and present conditions of life. Pragmatically, the
functional imperatives of the medical-hospital-pharmaceutical industry and the
funding needs and research interests of the biological science community make
the conviction that "mental disorder" fundamentally derives from
organic abnormality too valuable to abandon.
3. It has been known for many decades that neuroleptics
produce not only irreversible movement disorders, but also as a consequence of
their widespread pathophysiological effects in the brain, eventually produce
mental-emotional-behavioural impairments. The idea that any class of
psychoactive drug has only limited action that is restricted to specific
anatomical sites and specific neurotransmission systems is a fiction that
ignores what is actually known about the total anatomy and integrated
functioning of the brain.
4. The issue of the costs and risks connected to the
clinical use of a drug is a complex matter which involves both the natural
course of an illness as well as patient evaluation of the overall burdens
imposed by the illness compared to the overall burdens imposed by the
medications (among other considerations). The overall burdens imposed by the
medications is a massively under- developed topic in psychiatry, which is
subject to the usual medical reluctance to recognise iatrogenic illness and the
insidious deforming consequences of competitive pressure exerted by the
encroaching non-medical treatment professions. As for the natural course of
"psychiatric illnesses," psychiatric reliance on drug treatment has
enormously underplayed the actual variability in severity and degree of
distress/impairment across persons and over time intrapersonally, the responsiveness
of any "mental disorder" to variations in
social-interpersonal-material conditions of life, and the con- founding
consequences of many drugs and drug combinations over time.
5. The commitment to psychopharmacologic treatment can be
adequately understood only by including potent external (i.e., non-scientific)
influences on the development of psychiatry as a discipline and a profession in
the post World War II era, not the least of which has been the competition
posed by the emergence of encroaching professions.
6. Potent external (i.e., non-scientific) influences have
acted to move psychiatry into ever more vigorous assertions of the organic
roots of "mental disorder" and into a corresponding
psychopharmacologic nominalism for treatment purposes.
7. The catastrophe of medically-created illness of
unprecedented proportions on the part of psychiatry from the 1950s to the
present (which far exceeds its record of multiple "shock" therapies,
psychosurgeries, muscle relaxants, amphetamines, and barbiturates} has not
produced a critical self-examination within psychiatry of the ideological,
conceptual, financial, professional, and systemic factors which in combination
produced the catastrophe.
8. My contention that for all practical purposes nothing of
value has been learned from the catastrophe of the past forty years on the part
of psychiatry is illustrated in detail by examining the recent introduction of
two psychopharmacologic agents: alprazolam (Xanax) and fluoxetine (Prozac).
9. The most important lesson produced by the past forty
years of psychopharmacologic research with respect to the theoretical
understanding of psychopathology and practical lines of treatment alike is the
potent and consistent placebo effects which this literature has inadvertently
uncovered.
10. The entire question of the safety and efficacy of a
psychotropic drug for either acute or prolonged treatment must be removed from
the pharmaceutical industry-psychiatry-FDA cabal (Mosher and Burti, 1989, use
this term - a strong word coming from someone - Mosher - who was [to repeat]
NIMH's Chief of the Centre for Studies of Schizophrenia). Each arm of this
cabal is irretrievably compromised - although in the case of the giant,
for-profit pharmaceutical companies there is no realistic expectation in the
first place that they would place public good above profit maximisation. The
condition of genuine neutrality is an absolute minimum for trustworthy research
and policy making. Any suggestion for reform which does not recognise this
principle is thoroughly in bad faith.
