Buprenorphine Naltrexone-P1 A-Cocaine

January 11, 2017 updated by: National Institute on Drug Abuse (NIDA)

Attenuation of Opioid Effects of Three Different Doses of Sublingual Buprenorphine / Naloxone by Oral Naltrexone in Healthy Volunteers

The purpose of this study is to determine if the opioid agonist effects of doses of 4/1 mg, 8/2 mg, and 16/4 mg of buprenorphine/naloxone can be completely blocked by 50 mg of oral naltrexone. This study will provide data to support the design of a similar study of the depot formulation of naltrexone and ultimately to study this combination for the treatment of cocaine dependence.
