Buprenorphine versus methadone maintenance for the treatment of opioid dependence

Abstract

The results support the superiority of methadone with respect to retention rate. However, they also confirm previous reports of buprenorphine use as an alternative in maintenance therapy for opiate addiction, suggesting that a specific subgroup may be benefiting from buprenorphine. This is the first comparative trial to use sublingual buprenorphine tablets: previously published comparison studies refer to 30% solutions of buprenorphine in alcohol.
