The efficacy and tolerability of moclobemide (300-600 mg daily) and fl
uoxetine (20-40 mg daily) were compared in a 6-week, double-blind stud
y 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). Moclobe
mide (300-600 mg daily) and fluoxetine (20-40 mg daily) would thus app
ear 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, whi
le 40 mg fluoxetine/day does not. Sexual dysfunction was reported in t
wo patients taking fluoxetine.
