Description: Cariprazine, also known as RGH-188 and MP-214, is an antipsychotic drug received FDA approval on September 17, 2015. Cariprazine acts as a D2 and D3 receptor partial agonist, with high selectivity towards the D3 receptor. Action on the dopaminergic systems makes it also potentially useful as an add-on therapy in major depressive disorder. Cariprazine is approved for schizophrenia and bipolar disorder. It has also been investigated as a potential adjunct in treatment-resistant major depressive disorder.
