Actual date on which the first participant was enrolled.

This study investigates the effectiveness of a combination of two drugs, dextromethorphan and bupropion, compared to commonly used medications known as SSRIs, like sertraline or escitalopram, in treating major depressive disorder. The focus is on adult patients who are experiencing symptoms of major depression. By comparing these treatments, the study aims to determine if the new drug combination can potentially offer better relief from depression symptoms than the standard SSRI treatments. Understanding the effectiveness of these options is crucial as it might provide new insights and improvements in managing major depression. Participants in this study are divided into two groups, with one group receiving the dextromethorphan-bupropion combination and the other group receiving an SSRI treatment. The treatment period lasts for six weeks. Researchers will measure how well the participants respond to the treatments by using a depression rating scale to track remission rates. Additionally, they will examine changes in the severity of depressive symptoms and monitor any side effects or issues with tolerability, ensuring the safety of the treatments.
