They must have a Clinical Global Impression-Attention Deficit Hyperactivity Disorder-Severity Scale (CGI-ADHD-S) score greater than or equal to 4 at both the patients screening visit, prior to randomization.
- Patients must have laboratory results; showing no clinically significant abnormalities.
- Patients must be of normal intelligence, as assessed by the investigator.
- Patients/parents must have been judged by the investigator to be reliable to keep appointments for clinic visits and all tests, including venous punctures and examinations required by the protocol.
- Patients of child-bearing potential agree to use a reliable method of birth control during the study and for 1 month following the last dose of study drug. Female patients of child-bearing potential must test negative for pregnancy at the time of enrollment based on a urine pregnancy test.
