Summary

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).
