Introduction: Second generation antipsychotics (SGAs) have emerged as new treatment options for bipolar disorders (BDs). Aripiprazole (ARI) is already an SGA approved therapy for the treatment of BD type-I, both as a monotherapy as well as an add-on therapy in acute mania and in long-term maintenance therapy.
Areas covered: The authors provide a systematic review that illustrates ARI's pharmacological profile including its efficacy on various aspects of BD in adults. It also reviews its role in bipolar treatment algorithms and provides a focus on future research developments and further potential uses of the compound. Additional aspects such as safety and tolerability are also considered.
Expert opinion: Compared with haloperidol, ARI shows fewer extrapyramidal symptoms (EPS), but has a slightly lower efficacy in mania. It has a better metabolic parameter profile and fewer cardiovascular adverse events than other SGAs although the add-on treatment shows a higher risk of EPS. Presently, data doesn't support its use as a first choice maintenance monotherapy but it may be useful as a combination therapy for BD patients with comorbidities such as drug abuse and obsessive-compulsive disorders. Studies on ARI in bipolar depression are disappointing. However, future studies on the drug, at a low dose combined with a stabilizer or antidepressant may prove interesting.
