Outcome Measures
Primary Outcomes (1)
Test whether patients treated with atomoxetine 1.2 mg/kg/day who have sub-optimal clinical responses and peak plasma atomoxetine levels no higher than 800 ng/mL will benefit from a dose increase to 2.4 mg/kg/day
Secondary Outcomes (3)
Assess the relationship between plasma atomoxetine concentration levels and ADHD symptom response
Compare the efficacy of atomoxetine up to 2.4 mg/kg/day with atomoxetine at 1.2 mg/kg/day in reducing residual ADHD symptoms
Assess the safety and tolerability of atomoxetine at doses up to 2.4 mg/kg/day compared to 1.2 mg/kg/day in patients with peak plasma atomoxetine concentration levels no higher than 800 ng/mL as assessed by AEs elicited during open-ended questioning

Eligibility Criteria
You may qualify if:
- Outpatients who are at least 6 years of age and not more than 16 years of age at Visit 1
- Patients must meet DSM-IV diagnostic criteria for ADHD (any subtype)
- Patients must have laboratory results showing no significant abnormalities (significant would include laboratory deviations requiring acute medical intervention or further medical evaluation)
- Patients must be of normal intelligence as assessed by the investigator (that is, without a general impairment of intelligence and likely, in the investigator's judgment, to achieve a score of greater than or equal to 70 on an IQ test)
- Patients must be able to swallow capsules
You may not qualify if:
- Patients who weigh less than 25 kg or greater than 70 kg at study entry
- Patients with current or past Bipolar I or II disorder, psychosis, autism, Asperger's syndrome, or pervasive developmental disorder
- Patients with a history of any seizure disorder (other than febrile seizures) or patients who have taken (or are currently taking) anticonvulsants for seizure control
- Patients with a history of severe allergies to more than 1 class of medications or multiple adverse drug reactions
- Patients with cardiovascular disease or other conditions that could be aggravated by an increased heart rate or increased blood pressure
