Background and Objective
Selecting the most effective treatment for major depressive disorder (MDD) is a challenge for clinicians. The aim of this study was to compare the effects of sertraline with duloxetine on major depression signs and symptoms.
Methods
The trial was a 6-week, randomized, controlled, double-blind study. Sixty-three patients with diagnosis of MDD according to DSM-IV-TR criteria were randomly assigned to receive either duloxetine (31 patients) or sertraline (32 patients). The mean dosage of duloxetine was 55 mg/day (range 40–60 mg/day) and the mean dosage of sertraline was 146 mg/day (range 50–200 mg/day). Subjects were assessed at baseline, and at the end of week 6. Depression severity and symptoms were assessed by 21-item Hamilton Depression Rating Scale (HAM-D).
Results
Of 63 patients who were randomized to treatment, 54 patients including 28 in the sertraline group and 26 in the duloxetine group completed the trial. The HAM-D total score for both groups was significantly reduced at the end of the trial period without significant difference from each other (p = 0.463). Of the symptoms studied, psychomotor retardation, general somatic symptoms and sexual problems improved more in the duloxetine group. On the other hand, agitation, anxiety symptoms and hypochondriasis ameliorated better in the sertraline group. There was no difference between the two groups regarding the other symptoms.
Conclusions
Our study shows that the antidepressant mechanism of action has influence on its effects on different signs and symptoms. Clinician awareness of an antidepressant’s special effects can help in selecting appropriate medicine.
