[Combination of tricyclic antidepressants and MAOI in the depressions].

This study was aimed at the assessment of therapeutic and side effects of simultaneous administration of tricyclic antidepressants and MAOI. The sample consisted of 122 patients with depressive syndromes, treated at the "Centro de Psicología Médica San Martín de Tours" (period 1970/1973), with Isocarboxazide and Trimiprimine. All patients received both drugs three times a day. The average daily dose was 20 mg of Isocarboxazide together with 125 mg of Trimiprimine. The average treatment was 70 days long. The study lead to the following conclusions: 1. There were no serious side effects. 2. The scarce side effects registered were not very different from those of the other anti-depressants. 3. The therapeutic doses were lower than those required when each drug is used alone. 4. The speed of action was higher than for each drug separately. 5. The overall percentage of improvement in patients was higher than the percentage obtained for each drug alone. 6. The lack of side effects for a theoretically risky combination of drugs is likely to be attributed to the neuroleptic action of Trimipramine.
