Sertraline safety and efficacy in major depression: A double-blind fixed-dose comparison with placebo

In a 6-week, randomized, double-blind, multicenter trial, sertraline 50 mg, 100 mg, or 200 mg, or placebo, was administered once daily to 369 patients with DSM-III-defined major depression. Efficacy variables included changes from baseline scores for total Hamilton Rating Scale for Depression (HAMD), HAMD Bech Depression Cluster, Clinical Global Impressions (CGI) Severity, CGI Improvement, and Profile of Mood States Depression/Dejection Factor. For the evaluable-patients analysis, all sertraline groups showed significantly (p < 0.05 or better) greater improvements in all efficacy variables except one when compared with the placebo group. For the all-patients analysis, all efficacy variables in the 50 mg group were statistically significantly (p < 0.05) better than placebo. Side effects increased with increasing dosage but were usually mild and well tolerated. The results of this study show that sertraline 50 mg once daily is as effective as higher dosages for the treatment of major depression with fewer side effects and therapy discontinuations.
