First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a combination of dextromethorphan and bupropion works better than standard SSRI antidepressants for major depression. 80 adults with moderate to severe depression were randomly assigned to one of the two treatments for 6 weeks. Researchers measured changes in depression scores and remission rates to see which approach was more effective and tolerable.
