Aripiprazole for irritability associated with autistic disorder in children and adolescents aged 6-17 years.

Aripiprazole was recently US FDA-approved to treat irritability in children and adolescents with autistic disorder aged 6-17 years. There are currently only two psychotropics approved by the FDA to treat irritability in the autistic population. This drug profile will discuss available studies of aripiprazole in individuals with pervasive developmental disorders, two of which led to its recent FDA approval. We will discuss the efficacy, as well as the safety and tolerability of the drug documented in these studies. In addition, the chemistry, pharmacokinetics, metabolism and mechanism of action of aripiprazole will be reviewed.
