Study Summary

The investigators are proposing a randomized pilot feasibility study to evaluate the effects of galantamine versus placebo on preventing relapse to opioid use following tapering from methadone or buprenorphine maintenance (Medication Assisted Treatment, or MAT) among adults with opioid use disorder, with additional behavioral therapy (web-based cognitive behavioral therapy) provided across all conditions to help individuals successfully transition from MAT to a drug-free state.

Primary Outcome

Number of participants who were able to taper to 0 mg from methadone or buprenorphine over 10 weeks of treatment. Data about current medication and dose in mg was collected at the start of treatment (week 1) was recorded on a weekly medical sheet. Data was then collected weekly from participant self-report and verified through the clinic database.

Interventions
