Conditions

Major Depressive Disorder (MDD)

Brief summary

The study aims to compare the antidepressant effects of a dextromethorphan-bupropion combination versus standard SSRI therapy in adult patients with major depressive disorder. Participants will be randomized into two groups: one receiving dextromethorphan-bupropion and the other receiving an SSRI (e.g., sertraline or escitalopram). Treatment will last for 6 weeks, with assessments at baseline and study completion. The primary outcome will be the remission rate measured by a validated depression rating scale. Secondary outcomes include change in depressive symptoms severity and safety/tolerability measures.

Interventions

Participants will receive a fixed-dose combination of dextromethorphan-bupropion, dosed according to approved guidelines for major depressive disorder, administered orally for 6 weeks.

DRUGSSRIs

Participants will receive an SSRI at standard therapeutic doses, administered orally for 6 weeks.
