Peer perspective: learn how COBENFY, a first-in-class* M1/M4 schizophrenia treatment is thought to work2-5

Peer perspective featuring Doctor Gus Alva
Dr Gus Alva explains the mechanism of COBENFY, a first-in-class M1/M4 muscarinic agonist for the treatment of schizophrenia. COBENFY is a unique combination of xanomeline (M1M4 muscarinic agonist) and trospium chloride (muscarinic antagonist). Xanomeline is thought to work by selectively* activating M, and M, receptors. Although the mechanism of xanomeline in the treatment of schizophrenia is unclear, it is thought to work by selectively activating M, and M, receptors in the CNS. This activation is believed to help decrease dopamine in the CNS. Importantly, COBENFY does not bind to dopamine D receptors.2-5
Trospium chloride is thought to help limit muscarinic activation in the in the periphery.2

“It's been a long time coming, but I'm glad we're finally beginning to find alternate paths in the treatment of schizophrenia in adults.”
