The specific aim of this study is to document the pharmacokinetics of dopamine transporter
DAT receptor occupancy of OROS MPH and Metadate CD using PET scanning with C-11 Altropane as
the ligand. We hypothesize that CNS DAT occupancy of OROS MPH will be greater than that of
Metadate CD at 10 hours after administration.

This study was designed to compare Concerta Extended Release tablets with Metadate CD
capsules in children with ADHD who were between 6 and 12 years old. The effects on ADHD
symptoms, and any side effects of treatment, were measured for 12 hours after dosing in a
simulated classroom. The treatments were blinded and the effects were compared with a
Placebo.
