AXS-05 is a novel, oral, investigational NMDA receptor antagonist with multimodal activity being developed for the treatment of central nervous system (CNS) conditions. AXS-05 consists of a proprietary formulation and dose of dextromethorphan (DM) and bupropion.
- The dextromethorphan component of AXS-05 is an antagonist of the NMDA receptor, an ionotropic glutamate receptor, and a sigma-1 receptor agonist
- These actions modulate glutamatergic neurotransmission
- The bupropion component of AXS-05 serves primarily to increase the bioavailability of dextromethorphan, and is a norepinephrine and dopamine reuptake inhibitor
AXS-05 is an investigational drug not yet approved by the FDA.
