Auvelity: A New Era in Medicine - Unraveling the Multifaceted Benefits of Dextromethorphan/Bupropion Combination

Background: Depression is a prevalent global illness, impacting 280 million people worldwide, and Major Depressive Disorder (MDD) is ranked as the third leading cause of disease burden globally. People previously diagnosed with depression are more likely to develop Alzheimer's disease (AD). The recent approval of Auvelity by the FDA has made a remarkable breakthrough in drug development, offering a multi-dimensional approach for managing multiple diseases. Objective: The main objective of this study is to investigate the role of Auvelity, a new drug, in treating MDD and its potential to manage agitation in individuals with Alzheimer's disease (AD). Methodology: Data on Auvelity was collected from various sources, including accessdata.fda.gov, PubMed, and Scopus, and compiled for analysis. Discussion: Auvelity is the first oral medication to demonstrate the rapid onset of action, with statistically significant antidepressant efficacy observed as early as one week compared to a placebo. It contains a combination of dextromethorphan (45 mg) and bupropion (105 mg). The drug's mechanism of action involves a combination of NMDA receptor blockade and agonism of the sigma-1 receptor, resulting in the antagonization of the glutamatergic neurotransmitter pathway. Due to the similarity in the mechanism of action with AD medications like Memantine, there is a hypothesis that Auvelity could effectively reduce symptoms of AD. Conclusion: The approval of Auvelity marks a significant advancement in depression treatment with its unique NMDA antagonist mechanism, rapid onset of action, and low-risk profile.
