Buprenorphine in the treatment of opiate dependence.
Compelling clinical evidence establishes that buprenorphine is similar to methadone in efficacy for opiate detoxification and maintenance but safer than methadone in an overdose situation. The Drug Abuse Treatment Act of 2000 (DATA 2000) enabled US physicians with additional training to prescribe buprenorphine to a limited number of opiate-dependent patients. The sublingual tablets Subutex (buprenorphine alone) and Suboxone (a combination of buprenorphine and naloxone) meet the specifications of DATA 2000. Suboxone is intended to discourage intravenously administration and has less abuse potential than buprenorphine alone. Suboxone is generally recommended for maintenance treatment except for women who are pregnant. Subutex is recommended in treatment of pregnant women. A buprenorphine opiate withdrawal syndrome can occur in newborns. Although intravenous buprenorphine abuse is a significant public health problem in some countries, buprenorphine alone or in combination with naloxone has less potential for abuse than heroin and some prescription opiates, such as oxycodone. Pharmacotherapy from physicians' offices makes buprenorphine treatment acceptable to some opiate-dependent patients who would not accept treatment in traditional opiate-maintenance clinics. For reasons not adequately understood, some patients find discontinuation of buprenorphine following long-term use difficult. This article reviews the pharmacology of buprenorphine, summarizes evidence supporting the safety and efficacy of buprenorphine and provides clinical guidelines for treatment.
