A Study of Repeat Dosing of OROS® Methylphenidate Hydrochloride (CONCERTA®) and Immediate Release Methylphenidate Hydrochloride in Healthy Adults

Summary

This is a double-blind, randomized, placebo-controlled, five-period crossover study to examine the likability of a repeated administration of immediate release methylphenidate hydrochloride (IR-MPH 40 mg) and OROS®-MPH (CONCERTA® 72 mg) in healthy adults. Hypotheses are as follows: * Hypothesis 1: the subjective feelings of detection and likeability will be greater for periods of IR-MPH administration than after OROS-MPH administration irregardless of sequence; * Hypothesis 2: the greater ratings of feelings of detection and likeability will be associated with the periods of most rapid change in plasma d-MPH and not with the magnitude of plasma d-MPH concentration (other than the OROS-MPH to IR-MPH condition in which they coincide), and * Hypothesis 3: the subjective feelings of dislike will be greatest for the two conditions in which IR-MPH is the second condition.
