A Double-blind Randomized, Placebo-controlled, Crossover Study of Single Doses of OROS Methylphenidate Hydrochloride (CONCERTA) and Long-acting Methylphenidate Hydrochloride (RITALIN LA) in Healthy Adults
This is a double-blind, placebo-controlled study, three-period crossover study to examine the likeability of a single dose of OROS MPH (CONCERTAÒ 90mg) and a single dose of Long-acting MPH (RITALIN LAÒ 90mg). Hypotheses are as follows:
Hypothesis 1: OROS-MPH (CONCERTAÒ) will be later than SODOS-MPH (RITALIN LAÒ) in its Tmax (time to Cmax).
Hypothesis 2: The subjective feelings of detection and likeability would be greater for SODOS-MPH (RITALIN LAÒ) than for an equivalent total dose of OROS-MPH (CONCERTAÒ).
