Brief Summary
The purpose of this study is to compare the effectiveness (onset of effect, time to loss of effect, and overall efficacy) of methylphenidate given as an OROS® (methylphenidate HCl) formulation, compared to immediate-release Ritalin® and placebo for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in children using standardized attention and behavior scales, and other assessments. Both OROS® Methylphenidate HCl and Ritalin® contain the central nervous system stimulant, methylphenidate HCl.
