The Effect of Single High-dose Buprenorphine on Opioid Craving and Relapse [post]

2019 unpublished
Buprenorphine, a treatment for Opioid Use Disorder, has liability for diversion and abuse. Use of single high doses of buprenorphine that are supervised avoid issues with diversion that occur with unsupervised or take home doses. Such doses have the potential to act as an initial opioid detox, facilitate transition to opioid antagonists or drug free treatments, as well as to maintenance treatment. Objective: To assess effects of a single, physician-administered high dose of buprenorphine on

Method: Sixty men who used heroin, opium or prescription opioids and met DSM-5 criteria for Opioid Use Disorder received a single, sublingual dose of buprenorphine (32 mg, 64 mg or 96 mg; n's = 20, 21, and 19) as inpatients on a psychiatric unit. Buprenorphine was administered when patients were in moderate opioid withdrawal (4-5 symptoms). Self-reports of craving were taken at baseline and daily for the next 13 days, and relapse was assessed 1 and 2 months. Findings: Craving was reduced from baseline in each of the three groups (p < 0.0005), but the doseXtime interaction did not reach statistical significance (p= 0.069). Follow-up assessments at 1-and 2-months indicated significantly lower relapse rates for the higher-dose groups than for the low-dose group (p < 0.05). Conclusions: A single high dose of buprenorphine provides rapid relief of opioid craving and positively impacts relapse rate in the initial 1-and 2-months of outpatient treatment. Further investigation of single high-dose buprenorphine for early treatment of patients with Opioid Use Disorder is warranted as an alternative when buprenorphine/naloxone or long-acting buprenorphine dosage forms are not available.
