Moclobemide versus fluoxetine for a major depressive episode

Abstract

The efficacy and tolerability of moclobemide (300-600 mg daily) and fluoxetine (20-40 mg daily) were compared in a 6-week, double-blind study of 65 inpatients and 34 outpatients suffering from major depressive episodes (DSM III-R). No statistically significant differences between the two treatment groups were noted regarding efficacy (HDRS, CGI) or safety (adverse events, laboratory examination, vital signs). Moclobemide (300-600 mg daily) and fluoxetine (20-40 mg daily) would thus appear to be comparable both in antidepressant efficacy and tolerability. Doubling the low dosage in non-responders after 3 weeks resulted in a statistically significant improvement of CGI in the moclobemide group by comparison with the fluoxetine group at study end, suggesting that 600 mg moclobemide/day can still improve the patient's condition, while 40 mg fluoxetine/day does not. Sexual dysfunction was reported in two patients taking fluoxetine.
