CAS#: 913611-97-9

Description: Brexpiprazole, also known as OPC-34712, is a novel D2 dopamine partial agonist called serotonin-dopamine activity modulator (SDAM) approved for the treatment of schizophrenia, and as an adjunctive treatment for depression. Although it failed Phase II clinical trials for ADHD, it has been designed to provide improved efficacy and tolerability (e.g., less akathisia, restlessness and/or insomnia) over established adjunctive treatments for major depressive disorder (MDD). Brexpiprazole was approved on 7/10/2015 to treat schizophrenia and as an add on to an antidepressant to treat major depressive disorder
