Introduction: Aripiprazole is a novel second-generation antipsychotic approved for the treatment of bipolar disorder in adults but there is no systematic data available in pediatric bipolar disorder.
Methods: This was an 8-week, open-label, prospective study of aripiprazole 9.4+/-4.2 mg/day monotherapy to assess the efficacy and tolerability of this compound in treating pediatric bipolar disorder. Assessments included the Young Mania Rating Scale, Clinical Global Impressions-Improvement scale, and Brief Psychiatric Rating Scale. Adverse events were assessed through spontaneous self-reports, vital signs weight monitoring, and laboratory analysis.
Results: Fifteen of the 19 bipolar youth (79%) completed the study. Aripiprazole treatment was associated with clinically and statistically significant improvement in mean Young Mania Rating Scale scores (-18.0+/-6.9, P<.0001). With the important exception of two cases of extrapyramidal symptoms that precipitated dropout, aripiprazole was well tolerated with no statistically significant increase in body weight (1.8+/-1.7 kg, P=.2).
Conclusion: Open-label aripiprazole treatment was beneficial in the treatment of mania in youth with bipolar disorder. Future placebo-controlled, double-blind studies are warranted.
Trial registration: ClinicalTrials.gov NCT00181779.
