An Open-Label Trial of Aripiprazole in Children and Adolescents With Bipolar Disorder

The primary aim of this study is to assess the effectiveness, safety, and tolerability of aripiprazole for the treatment of children and adolescents with bipolar disorder. The secondary aim of this study is to determine if common polymorphic variations in the CYP 2D6 gene underlie the inter-individual variability in aripiprazole systemic drug exposure and the occurrence of treatment emergent side effects.
