Pharmacotherapy of attention-deficit hyperactivity disorder in children and adolescents: update on new stimulant preparations, atomoxetine, and novel treatments.

This article reviews data on the safety, tolerability, and efficacy of the extended-delivery stimulant preparations and atomoxetine, including nine methylphenidate formulations, five amphetamine formulations, and one norepinephrine reuptake inhibitor, now indicated for treatment of attention-deficit hyperactivity disorder (ADHD). Six of the nine methylphenidate formulations, three of the five compounds, and the norepinephrine reuptake inhibitor are long-acting, potentially once-daily agents. Data on treatment of common adverse events are described, and data on investigational treatments of ADHD are reviewed.
