Fluoxetine vs. tricyclic antidepressants in women with major depressive disorder.
Major depressive disorder and dysthymia are twice as prevalent in women as in men, and the lifetime risk of a woman's developing a major depressive disorder is about 20%. Yet depression is often unrecognized or misdiagnosed in women, and only about one quarter of women who meet criteria for major depressive disorder receive appropriate therapy. Until recently, women were generally excluded from clinical drug trials because of concerns of inadvertent pregnancy and risk of teratogenicity. Thus, information on safety and efficacy in those most likely to require antidepressant therapy is lacking. Studies have shown that the antidepressant fluoxetine, a selective serotonin reuptake inhibitor (SSRI) has a more tolerable side effect profile than do tricyclic amine (TCA) antidepressants, but few data have been reported on the efficacy and tolerability of fluoxetine or other SSRIs in female patients. In this study, a retrospective analysis of 11 randomized, double-blind, well-controlled trials was done to compare data from 427 female patients on fluoxetine and 423 female patients on TCAs. Both fluoxetine and TCAs significantly reduced the HAMD17 total mean score from baseline to end point, week 5 (fluoxetine, 24.35 to 14.37; TCAs, 24.57 to 14.43; p < 0.001). Both treatment groups were associated with significant reductions in the HAMD17 anxiety/somatization and insomnia subfactor scores. Abnormal vision, constipation, dizziness, dry mouth, and somnolence occurred more frequently (p < 0.05) in the TCA group. Insomnia and nausea were the only adverse events more common (p < 0.05) in the fluoxetine group. This study demonstrates that fluoxetine is an effective and tolerable agent for the treatment of major depressive disorder in women.
