Brief summary
The purpose of this study is to treat Adult Attention Deficit Hyperactivity Disorder (ADHD) in methadone patients.
Detailed description
This project is a three armed double-blind, placebo-controlled, randomized trial comparing the efficacy of MPH and BPR, relative to each other and to placebo, for treating persistent ADHD in methadone-maintained patients. One hundred and twenty subjects, will be randomized to receive either MPH, BPR, or placebo with equal probability. Randomization will be stratified by site, and whether or not cocaine is also being used. Efficacy will be measured by treatment retention, reduction in illicit drug use and drug craving, improvement of ADHD symptoms and overall functional status.
