Omega-3 as an adjunctive therapy of sertraline and venlafaxine substantially improves symptoms of major depressive disorder: A double-blind, placebo-controlled study
Abstract
Due to the possible effect of omega-3 fatty acids on reducing depressive symptoms, in this study, we investigated these effects in combination with other antidepressants.
The study was a double-blind clinical trial on 100 patients with major depressive disorder who were divided into four groups of 25 each and treated with 50 mg daily sertraline plus placebo, 50 mg daily sertraline plus two grams Omega 3 daily, 75 mg daily venlafaxine plus placebo, and 75 mg daily venlafaxine plus 2 g Omega 3 daily for 6 weeks.
The mean Hamilton depression rating score of sertraline and venlafaxine plus omega-3 after treatment were 4.42 and 4.23 respectively versus sertraline and venlafaxine plus placebo 14.4 and 14.2 respectively (P value=0.0001).
Omega-3 enhanced the clinical function of sertraline and venlafaxine to reduce the severity of depression. Adding omega-3 to either sertraline or venlafaxine does not have a comparative advantage over each other in terms of the improvement of severity of depressive symptoms.
