What is Cariprazine?

Cariprazine (Vraylar) is an antipsychotic used to treat schizophrenia, specific types of bipolar I disorder, and as an add-on treatment for major depressive disorder (MDD). Cariprazine is from the drug class atypical antipsychotics.

Cariprazine is thought to work by managing chemicals in the brain (neurotransmitters), including serotonin and dopamine. Although the mechanism of action of cariprazine is unknown, its effect may be from a combination of partial agonist activity at central dopamine D₂ and serotonin 5-HT1A receptors and antagonist activity at serotonin 5-HT2A receptors.

Cariprazine is specifically indicated to treat adults with:

• Schizophrenia
• Acute manic or mixed episodes associated with bipolar I
• Depressive episodes associated with bipolar I disorder (bipolar depression) 
• Adjunctive treatment with an antidepressant therapy (ADT) for major depressive disorder (MDD).

Cariprazine, under the brand name Vraylar, became an FDA-approved medicine on September 17, 2015.
