"...Auvelity (dextromethorphan/bupropion) is a novel, rapid-acting oral medication approved for major depressive disorder (MDD) and Alzheimer’s-related agitation. Its dextromethorphan component acts as an agonist (activator) at the sigma-1 receptor, playing a key role in the drug's antidepressant and neuroprotective effects.
How the Sigma-1 Receptor Works in AuvelityMechanism:
Mechanism:
Dextromethorphan binds to and activates the sigma-1 receptor, a chaperone protein located in the brain's endoplasmic reticulum.
Neurotransmission:
This activation helps regulate and modulate glutamatergic signaling—the pathways often dysregulated in depression and Alzheimer's disease.
Neuroprotection:
Sigma-1 receptor activation yields potent protective effects by reducing cellular stress, supporting mitochondrial health, and encouraging neuronal plasticity (the brain's ability to adapt and form new connections).
Sigma-1 activation is the major mechanism of action for Auvelity.
