Aripiprazole is an atypical antipsychotic and a partial dopamine agonist. It is primarily used in the treatment of schizophrenia, bipolar disorder, major depressive disorder, tic disorders, and irritability associated with autism. Aripiprazole was first approved by the U.S. Food and DrugAdministration in November 2002 for schizophrenia and by the European Medicines Agency in June 2004 for acute manic and mixed episodes associated with bipolar disorder.
