The Effect of Adding Curcumin to Sertraline in the Treatment of Severe Major Depressive Disorder: A Randomized, Double-Blind Clinical Trial

Major depressive disorder (MDD) is a chronic and debilitating disease influenced by inflammatory processes in the brain. Some evidence has represented the adding curcumin as a complementary regime to the standard medication in treating depressive symptoms. However, limited clinical trials have been conducted on the antidepressants effects of curcumin in MDD patients. Therefore, this study aimed to investigate the effectiveness of curcumin in the treatment of MDD.In a randomized, double-blind clinical trial, 45 severe MDD patients referred to the psychiatric clinic of Ibn-e-Sina Hospital, Mashhad, Iran, during 2016 were selected. Patients were randomly divided into 2 groups who received sertraline plus curcumin or placebo at a dose of 40 mg/d for 8 weeks. The patients were evaluated using Beck Anxiety and Depression Surveys at the beginning of the study, fourth, and eighth weeks by a psychiatry resident. The data analyzed aiding SPSS software.While depression and anxiety significantly decreased during the 8 weeks of the study, there was no significant difference between the 2 groups (P > 0.05). However, the anxiety score was lower in the intervention group. Moreover, no severe adverse events were observed in all patients.Adding 40 mg/d of SinaCurcumin to sertraline as a routine medical regimen did not improve the depression and anxiety levels in severe MDD patients. However, the anxiety score was lower in the intervention group than in the placebo receiver, which suggests curcumin may have a more effect on anxiety.
