[Novel comparative profile of the clinical activity of antidepressive agents].

In order to develop practical criteria to guide in the selection of antidepressant medication according to depressive symptomatology, we propose a graphical representation of the clinical activity of 24 antidepressants according to a "star" model. Six parameters have been evaluated from 0 to 5 in comparison to reference drugs (rated 5) by 11 independent "blind" psychiatrists expert in pharmacotherapy. Three parameters were used as measures of therapeutic activity: antidepressant, psychostimulant, and anxiolytic, with iproniazide 75 mg/d, metamphetamine 15 mg/d, and diazepam 20 mg/d as reference drugs respectively. Three additional parameters assessed the level of side-effects: anticholinergic, sedative, and hypotensive, with atropine 0.75 mg/d, phenobarbital 200 mg/d, and iproniazide 75 mg/d as reference drugs respectively. The defined dose represented the standard maintenance daily dose for depressive outpatients. Mean values for each parameter, rounded off to the closest number, were used for the graphical representation. Results showed an excellent agreement among evaluators for the clinical profile of classical tricyclic and MAOI antidepressants, but serious divergences for the more recent drugs (e.g., viloxazine and mianserine), possibly reflecting more atypical or more variable clinical profile of these compounds.
