Atomoxetine to Treat Asian Adult Patients With Attention-Deficit/Hyperactivity Disorder

The purpose of this study is to assess the efficacy, the quality of life, and the safety of multiple dosing atomoxetine in Asian adult subjects with attention deficit/hyperactivity disorder (ADHD).

The treatment will be initiated at the lowest dosage 40 milligrams per day (mg/day), and it will be titrated up to 80 mg/day. Patients who are unable to tolerate a dose of at least 80 mg/day through the end of this study will be discontinued. The dosage will be titrated up to a maximum of 120 mg/day.
