Aripiprazole in children and adolescents: clinical experience.

Despite few supportive data, aripiprazole was being administered to children and adolescents for management of mood instability, aggression, and psychosis. Using a retrospective review (n = 11) and prospective recruitment (n = 6), 17 children and adolescents received aripiprazole 5 to 20 mg/day. Only 4 of 16 bipolar and autistic subjects (25%) demonstrated reduced aggression without adverse events, and the symptoms of 2 of 4 psychotic subjects improved. Coadministration of sedative medications (particularly guanfacine or clonidine) and weight < 58 kg increased the risk of adverse events, such as increased lability and aggression. All three children < 8.6 years old, all four children < 34 kg, and all five children receiving alpha(2)-agonists developed adverse events prior to clinical efficacy. Age > 11 years, weight > 58 kg, and absence of sedative medications were associated with a 56% (five of nine) success rate. Until larger, prospective studies are completed, caution is advised when considering aripiprazole for smaller children and children receiving sedative medications.
