A Comparison of Fluoxetine Imipramine and Placebo in Patients with Bipolar Depressive Disorder

Abstract

This was a 6-week, double-blind comparison of fluoxetine, imipramine, and placebo in 89 patients with bipolar depression. Using the criteria of greater than or equal to 50% improvement in the HAMD-total score after at least 3 weeks on study drug, endpoint analysis showed 86% of the fluoxetine-treated patients improved compared with 57% of the imipramine-treated and 38% of the placebo-treated patients. Significantly fewer fluoxetine-treated patients discontinued due to adverse events than did imipramine-treated patients (7% vs. 30%, respectively).
