About Brexpiprazole

Brexpiprazole is a novel investigational psychotropic compound discovered by Otsuka and under co-development with Lundbeck. Brexpiprazole is a serotonin-dopamine activity modulator (SDAM), which means that the drug is a partial agonist at 5-HT1A and dopamine D2 receptors at relatively equal potency, an antagonist at 5-HT2A and an antagonist at noradrenaline alpha1B/2C receptors. A New Drug Application for brexpiprazole has been filed with the U.S. Food and Drug Administration (FDA) and the PDUFA date is in July 2015.
