What is being tested?
The study is testing if fMRI can show changes in the brain's reward system when given Naltrexone, an opioid blocker, compared to a placebo. Participants will randomly receive either Naltrexone or placebo first, then switch to the other after a period of time.See study design
What are the potential side effects?
Naltrexone may cause nausea, headache, dizziness, fatigue, insomnia or anxiety. It might also trigger withdrawal symptoms in those who've recently used opioids.
