Abstract
Data from 38 double-blind and two single-blind studies with moclobemide vs. placebo and/or standard antidepressants (10 drugs) were available for an intent-to-treat meta-analysis (n = 2,371). In all, 236 subjects received placebo and 1,107 moclobemide. As a measure of efficacy, a > or = 50% decrease from the baseline on the Hamilton Rating Scale for Depression (HAM-D) and its new subscales was taken. Furthermore, the Global Assessment of Efficacy (GAE) was analyzed. New subscales of the HAM-D consist of a retarded depression and an agitation/anxiety scale. The two factors were obtained from factor analyses of 12 x 8 random subsamples resulting in a stable solution. The subjects were subclassified by severity (low, medium, high) prior to treatment. The response to placebo was consistently lower in high scorers. In contrast to that, high scorers on active drugs (moclobemide, imipramine, and clomipramine) showed a tendency to higher response rates. Response rates were, in general, higher on the subscale retarded depression than on agitation/anxiety for both placebo and active drugs. Response rates to moclobemide were highest in unipolar endogenous depressives (66%) followed by bipolars (57%), neurotic depressives (52%), and reactive depressives (43%).
