Introduction: Almost 30%–50% of the patients with major depressive disorder can be categorised as treatment-resistant depression (TRD). The use of augmenting agents such as aripiprazole (ARI) and quetiapine (QP) to the existing antidepressant (AD) therapy could be a suitable alternative for treating TRD. The superiority of anyone over others is not established in short-term studies. Hence, the present study was performed to compare the safety and efficacy of ARI and QP for the treatment of TRD. Materials and Methods: In the present study, a total of 50 patients with TRD who showed insufficient response to at least two ADs for 12 weeks were enrolled. The participants were assigned randomly in a double-blind trial to receive ARI (10 mg/day; n = 25) or QP (300 mg/day; n = 25) in addition to their standard AD therapy for 12 weeks. Montgomery–Åsberg Depression Rating Scale (MADRS) and the Clinical Global Impressions (CGI) scale were used to measure treatment efficacy. The safety was evaluated by recording treatment-caused adverse effects (AEF). Results: A significant decrease in MADRS score was observed with ARI groups than in the QP group (‒7.5; ‒4.6, P < 0.001). The CGI scores in the ARI group also exhibit significant improvement compared with the QP group. There was a non-significant change in CGI score recorded in both groups. The AEF was observed in 11% of patients with more incidences in the QP groups. The incidences of AEFs resulting in discontinuation of therapy were found low in both groups (ARI: 1.6%; QP: 3.2%). Conclusion: The findings of this study conclude that TRD patients can be more benefitted by ARI augmentation therapy than QP.
