Influence of gender and menopausal status on antidepressant treatment response in depressed inpatients

Abstract: The present study investigated the influence of gender and menopausal status on treatment response in depressed inpatients, treated with either imipramine or fluvoxamine. The patients were divided into three groups: men, premenopausal women and postmenopausal women. A multivariate analysis was performed using the difference in Hamilton score (pretreatment - post-treatment) for imipramine and fluvoxamine as dependent variable. The following independent variables were used: the baseline Hamilton score, the antidepressant used, the gender-group and the interaction between the type of antidepressant and gender. In total, 138 patients with a DSM IV diagnosis of depressive disorder were analysed. Men responded more favorably to imipramine (B = 7.12, P = 0.005). Premenopausal women had a better response rate to fluvoxamine than men (B = -8.66, P = 0.027). In depressed inpatients, men respond more favorably to imipramine than to fluvoxamine. Premenopausal women respond more frequently to fluvoxamine than men.
