Summary
The purpose of this study is to evaluate a very low dose naltrexone-buprenorphine treatment to transfer opioid dependent individuals to extended release naltrexone injection (Vivitrol). The hypothesis is that patients will complete the transfer to Vivitrol successfully, finding the treatment acceptable and showing minimal withdrawal discomfort.
