This study will evaluate the effectiveness of a new pharmacological approach to increase efficacy of treatment with extended release naltrexone (XR-naltrexone) for individuals with opioid use disorder by combining it with buprenorphine-naloxone. This is a two arm, double-blind, placebo-controlled study to examine whether addition of buprenorphine-naloxone will improve treatment retention, reduce opioid craving, and improve mood over 24 weeks of treatment with extended release naltrexone (XR-naltrexone) administered every four weeks for a total of 6 injections.
This study will evaluate the effectiveness of a new pharmacological approach to increase efficacy of treatment with extended release naltrexone (XR-naltrexone) for individuals with opioid use disorder by combining it with buprenorphine-naloxone. Adding buprenorphine-naloxone after the patient initiated XR-naltrexone will not produce mu opioid agonist effect but kappa antagonist effects of buprenorphine may provide additional relief of protracted withdrawal, craving, and mood disturbances persisting in patients treated with XR-naltrexone and possibly contributing to premature treatment disconti…
