An oral, fixed-dose combination of dextromethorphan hydrobromide [an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist and sigma-1 receptor agonist] and the antidepressant bupropion hydrochloride (an aminoketone and CYP2D6 inhibitor that increases dextromethorphan bioavailability) [AUVELITYTM; dextromethorphan/bupropion], is being developed by Axsome Therapeutics, Inc. for the treatment of major depressive disorder (MDD), Alzheimer’s disease agitation and smoking cessation. Dextromethorphan/bupropion was approved in the USA in August 2022 for the treatment of MDD in adults. This article summarizes the milestones in the development of dextromethorphan/bupropion leading to this first approval for the treatment of adults with MDD.
