NIDA Clinical Trials Network CTN-0051 Extended-Release Naltrexone vs. Buprenorphine for Opioid Treatment (X:BOT): Study Design and Rationale

摘要

IntroductionFor opioid-dependent patients in the US and elsewhere, detoxification and counseling-only aftercare are treatment mainstays. Long-term abstinence is rarely achieved; many patients relapse and overdose after detoxification. Methadone, buprenorphine-naloxone (BUP-NX) and extended-release naltrexone (XR-NTX) can prevent opioid relapse but are underutilized. This study is intended to develop an evidence-base to help patients and providers make informed choices and to foster wider adoption of relapse-prevention pharmacotherapies.
