ClinConnect Summary

This clinical trial is studying the effectiveness of a combination treatment using naltrexone and bupropion for individuals struggling with methamphetamine use disorder (MUD). The goal is to find out if this treatment can help people reduce or stop their use of methamphetamine more effectively than a placebo (a treatment with no active medication). The trial is currently recruiting participants who are between the ages of 18 and 65, and who have been diagnosed with moderate to severe MUD. To qualify, individuals should have used methamphetamine on multiple occasions in the month before signing up and must be interested in reducing or quitting their drug use.

Participants in this study can expect to receive either the active medication or a placebo, and they will be monitored closely throughout the trial. They will also need to use a smartphone app to record their medication intake daily. It's important to note that there are specific health criteria that need to be met for eligibility, such as not being physically dependent on opioids and not having certain medical or psychiatric conditions. This trial aims to provide valuable information that could lead to better treatments for those facing challenges with methamphetamine use.
