ABSTRACT
Several arguments are in favour of the use of
antidepressant drugs in alcohol-dependent patients, especially those acting on
the serotoninergic system (1) neurochemical data indicate the interaction
between alcohol and 5-HT metabolism, (2) pharmacological studies show an
improvement in the behaviour of alcoholized animals treated with
antidepressants, (3) depression is a frequent disease in alcoholic patients.
Tianeptine has been shown to be active in the treatment of depression in
patients with history of alcohol abuse or dependence. In a first double-blind
study performed versus amitryptiline, depression after withdrawal was improved
by tianeptine, and biological abnormalities usually related to chronic alcohol
intake tended to decrease. Similar results were found in an open study carried
out on 277 alcoholic patients treated for 1 year. As these patients were
depressed, no definite conclusion could be drawn from these results in respect
of a specific action of tianeptine on alcohol dependence. Thus, a multicentre
double-blind study has been performed which compared tianeptine (12.5 mg t.i.d)
and placebo in 342 non-depressed patients fulfilling DSM-III-R criteria for
Psychoactive Substance Dependence (alcohol). Other inclusion criteria were
daily alcohol intake higher than 80 g, minimum score of 3 on the Short-Mast
Questionnaire, mean corpuscular volume above 98 fl and/or gamma Gt more than
twice the upper limit of normal. The patients were treated for 9 months. The
intention-to-treat population and the per protocol population were made up of
327 patients and 111 patients, respectively. The main efficacy criterion was
the absence of alcoholic relapse (abstinence) defined by the patient's
statements, the investigators clinical judgement and some biological
parameters alcohol blood levels, gamma Gt levels. Secondary criteria were the
evolution of the alcohol consumption in the patients who relapsed, cumulative
abstinence duration, a visual analogue scale for the evaluation of the
appetence for alcohol and the clinical global impressions scale. The
statistical analysis showed no difference between both groups in respect of
the maintenance of abstinence (intention-to-treat and per protocol
populations). In spite of the methodological problems of the studies in
dependence (choice of the inclusion and efficacy criteria, especially), the
preliminary results obtained with the serotoninergic antidepressants were not
confirmed in the different trials performed in the maintenance of alcohol
abstinence. The indication of tianeptine should be restricted to the treatment
of depressive syndromes, which have a high lifetime prevalence in the
alcoholic patient, and which have a noticeable role on the alcoholic relapse.
