Buprenorphine (Subutex) is widely abused in Finland. A combination of buprenorphine plus naloxone (Suboxone) has been available since late 2004, permitting a comparison of the abuse of the two products among untreated intravenous (IV) users. A survey was distributed to attendees at a Helsinki needle exchange program over 2-weeks in April, 2005, At least 30% were returned anonymously. Survey var...
Although only a partial mu-opiate agonist, buprenorphine can be abused and diverted from medical therapy to the illicit drug market. A combination of buprenorphine and naloxone for sublingual administration may discourage diversion and abuse by precipitating opiate withdrawal when taken parenterally. Because opiate-abusing populations are not homogeneous and have varying levels of opiate depend...
In October 2002, the U.S. Food and Drug Administration approved buprenorphine-naloxone (Suboxone) sublingual tablets as an opioid dependence treatment available for use outside traditionally licensed opioid treatment programs. The NIDA Center for Clinical Trials Network (CTN) sponsored two clinical trials assessing buprenorphine-naloxone for short-term opioid detoxification. These trials provid...
BACKGROUND There is growing evidence about illicit use of buprenorphine in the U.S. The study aims to: (1) identify prevalence and predictors of illicit buprenorphine use in a community sample of 396 young adult (18-23 years old) non-medical users of pharmaceutical opioids and (2) describe knowledge, attitudes and behaviors linked to illicit buprenorphine use as reported by a qualitative sub-sa...
Background: Since the number of drug users is increasing, applying a method of detoxification with fewer side effects during withdrawal from opioids and greater reliability seems to be necessary. In addition, without maintenance treatment, there will be limited success of treatment. This study aimed to compare success rates of detoxification with sublingual buprenorphine and clonidine and to ev...
Buprenorphine (Subutex®; Suboxone® buprenorphine and naloxone in combination) is since more than 12 years a fully accepted treatment choice for opioid dependence in Austria. In Austria up to now buprenorphine has reached like in France the status of a first choice medication together with methadone maintenance treatment. Until now the potential of buprenorphine as a treatment choice is not full...
BACKGROUND Buprenorphine is under investigation as a pharmacotherapeutic agent for treating opioid dependence in pregnant women. We hypothesized that there would be a relationship between the cumulative maternal dose of buprenorphine during pregnancy and the concentration of buprenorphine and norbuprenorphine in maternal and infant hair. METHODS This study examined buprenorphine and norbupren...
BACKGROUND The long-lasting high-affinity opioid buprenorphine has complex pharmacology, including ceiling effects with respect to analgesia and respiratory depression. Plasma concentrations of the major buprenorphine metabolites norbuprenorphine, buprenorphine-3-glucuronide, and norbuprenorphine-3-glucuronide approximate or exceed those of the parent drug. Buprenorphine glucuronide metabolites...
Several sources indicate that intravenously administered buprenorphine may have significant abuse liability in humans. The present study evaluated the reinforcing effects of intravenously administered buprenorphine (0, 2, and 8 mg) in detoxified heroin-dependent participants during a 7.5-week inpatient study. Participants (n = 6) were detoxified from heroin over a 1.5-week period immediately af...
Buprenorphine is mainly metabolized by the cytochrome P450 (CYP) 3A4 enzyme. The aim of this study was to evaluate the role of first-pass metabolism in the interaction of rifampicin and analgesic doses of buprenorphine. A four-session paired cross-over study design was used. Twelve subjects ingested either 600 mg oral rifampicin or placebo once daily in a randomized order for 7 days. In the fir...
