Clinical Trial Summary

Methamphetamine is an addictive stimulant drug that strongly activates certain parts of the brain. The purpose of this study is to determine the effectiveness of bupropion in combination with behavioral therapy for the treatment of methamphetamine addiction.


Description:

Methamphetamine is a drug that causes excess amounts of the neurotransmitters dopamine and norepinephrine to be released into the brain. This overload produces unusual alertness and feelings of elation. When the body undergoes methamphetamine withdrawal, it experiences a reduction in dopamine and norepinephrine. Bupropion is an antidepressant used for the treatment of depression and smoking cessation. Because it functions by increasing the release of dopamine and norepinephrine in the brain, bupropion is likely to decrease the negative effects of methamphetamine withdrawal. The purpose of this study is to evaluate the efficacy of bupropion combined with contingency management (CM) and cognitive behavioral counseling (CBT) as a means of treating methamphetamine dependence.

An initial 2-week screening process will involve participants providing urine samples and completing physical and psychological assessments. If deemed eligible for the remainder of this double-blind study, participants will be randomly assigned to receive either bupropion or placebo over the course of 12 weeks. Participants in both the bupropion and placebo groups will receive contingency management and cognitive behavioral counseling. Participants will report to one of two clinical research sites three times per week. At each visit, participants will be examined by the study staff, provide a urine sample, and receive individual cognitive behavioral counseling sessions. At the end of 12 weeks, treatment will be stopped. Participants will return to the study site 30 days later for evaluation and to be assessed for any possible lingering side effects.
