OBJECTIVES: This study evaluated flexible-dose pharmacokinetics, safety, and effectiveness of aripiprazole in children and adolescents with conduct disorder (CD). METHODS: This open-label, 15-day, three-center study with an optional 36-month extension enrolled a total of 23 patients: 12 children (6-12 years) and 11 adolescents (13-17 years) with CD and a score of 2-3 on the Rating of Aggression Against People and/or Property (RAAPP). Initially, the protocol used the following dosing: subjects <25 kg, 2 mg/day; subjects 25-50 kg, 5 mg/day; subjects >50-70 kg, 10 mg/day; and subjects >70 kg, 15 mg/day. Due to vomiting and sedation, this schedule was revised to: <25 kg, 1 mg/day; 25-50 kg, 2 mg/day; >50-70 kg, 5 mg/day; and >70 kg, 10 mg/day. RESULTS: Aripiprazole pharmacokinetics were linear, and steady state appeared to be attained within 14 days. Both groups demonstrated improvements in RAAPP scores and Clinical Global Impressions-Severity (CGI-S) scores. Adverse events were similar to the known profile for aripiprazole in adults. CONCLUSION: The pharmacokinetics of aripiprazole in children and adolescents are linear and comparable with those in adults. Aripiprazole was generally well-tolerated in patients with CD, particularly after protocol adjustments, with improvements in aggressive behavior.
