Buprenorphine Treatment for Opioid Dependence

Yale University9 enrolled

Overview

Buprenorphine/naloxone (BUP/NLX) treatment is effective for the treatment of prescription opioid dependence, previous studies have not determined the optimum dose of BUP/NLX for this patient population. The goal of this study is to determine if there are differences in clinical efficacy of BUP/NLX tablet in low dose range (less than or equal to 8/2mg) vs. high dose range (greater than or equal to 16, range 16-24mg). The main outcomes of interest will be treatment retention, use of opioids, and the use of other drugs of abuse.

This is a randomized, open-label clinical trial with approximately 9 Veteran opioid dependent men and women. Veterans were randomized to one of two treatment groups: low dose range of buprenorphine (\<8mg) vs. high dose range of buprenorphine/naloxone (BUP/NLX (\<16mg). During induction into buprenorphine, all participants will be started at a dose of 2mg, and this dose will be increased as needed for stabilization of opioid withdrawal symptoms, up to 8mg for the low dose group, and up to 16mg for the high dose group, within a 5 day period. Participants will be seen on a daily basis (excluding weekends) for the initial 5 day induction. At the end of the 12-week study, participants will either be referred to a buprenorphine clinic if they wish to continue this medication, or if they wish to be drug free, will undergo detoxification from buprenorphine for up to a 4-week period. Follow-up visits, scheduled at 1, 3, and 6 months after study completion.
