Effectiveness of aripiprazole v. haloperidol in acute bipolar mania: double-blind, randomised, comparative 12-week trial.

Abstract

Despite several treatmentoptions, adherenceto therapy is poor in patients with bipolar disorder. A double-blind, controlled comparison of aripiprazole and haloperidol in patients with bipolar I disorder experiencing acute manic or mixed episodes. Patients (n=347) were randomised to receive aripiprazole or haloperidol in this 12-week, multicentre study. The primary outcome measure was the number of patients in response (greater, similar 50% improvement from baseline in Young Mania Rating Scale score) and receiving therapy at week 12. At week 12, significantly more patients taking aripiprazole (49.7%) were in response and receiving therapy compared with those taking haloperidol (28.4%; P < 0.001). Continuation rates differed markedly between treatments (week 12: aripiprazole, 50.9%; haloperidol, 29.1%). Extrapyramidal adverse events were more frequent with haloperidol than aripiprazole (62.7% v. 24.0%). Aripiprazole showed superior levels of response and tolerability to haloperidol in the treatment of an acute manic episode for up to 12 weeks.
