A Randomized, Placebo-Controlled Trial of Modafinil for Methamphetamine Dependence

The proposed study will establish the safety and efficacy of modafinil in the treatment of methamphetamine dependence, as well as assess the affects of modafinil on cognitive function in methamphetamine users and on methamphetamine withdrawal symptoms. In this outpatient trial, methamphetamine- dependent, treatment-seeking subjects will receive modafinil or placebo daily for four weeks, along with weekly Motivational Enhancement Therapy sessions. This study will be conducted at the Addiction \& Pharmacology Laboratory in San Francisco, CA, and at the New Leaf Treatment Center in Lafayette, CA, and is expected to last one year.
