Buprenorphine is a mixed opioid receptor agonist-antagonist used in acute and chronic pain management. Although this agent's analgesic effect increases in a dose-dependent manner, buprenorphine-induced respiratory depression shows a marked ceiling effect at higher doses, which is considered to be an indicator of safety. Nevertheless, cases of overdose mortality or severe respiratory depression ...

Buprenorphine is used as a sublingual medication in the treatment of opioid dependence. However, its misuse by i.v. injection may limit its acceptability and dissemination. A buprenorphine/naloxone (ratio 4:1) combination has been developed to reduce diversion and abuse. So far, the relevance of this combination has not been investigated in the animal models traditionally used to study the rein...

A method for the simultaneous measurement of buprenorphine and its N-dealkylated metabolite, norbuprenorphine, in human plasma was developed with negative chemical ionization tandem mass spectrometry. Buprenorphine and norbuprenorphine were extracted from biological fluids by solid-phase extraction. The samples were derivatized with heptafluorobutyric anhydride and measured with negative chemic...

analysis comparing the effectiveness of buprenorphine and methadone. Research question Is buprenorphine as effective as methadone for managing opioid dependence? Type of article and design Meta-analysis by three reviewers. Relevance to family physicians Community-based family physicians are uniquely suited to care for opioid-dependent patients. Buprenorphine, like methadone, is a substitution t...

In addition to buprenorphine monotherapy tablets, film and tablets combining 4 parts buprenorphine and 1 part naloxone (a mu opioid antagonist) are also being used in maintenance treatment for opioid dependence (Chiang and Hawks, 2003). (The original manufacturer of the combination tablets stopped supplying them but generic versions and new brand, Zubsolv®*, are now available.) In fact, the bup...

Buprenorphine is a partial μ-opioid receptor agonist used for the treatment of opioid dependence that has several advantages over methadone. The principal route of buprenorphine disposition has been well established; however, little is known regarding the potential for buprenorphine to influence the metabolism and clearance of other drugs by affecting the expression of drug-metabolizing enzymes...

  Background: Postoperative pain is a common side effect following surgery that can significantly reduce surgical quality and patient’s satisfaction. Treatment options are morphine and buprenorphine. We aimed to compare the efficacy of a single dose of intravenous morphine with sublingual buprenorphine in postoperative pain control following closed reduction surgery. Methods: This triple blind ...

Buprenorphine is a partial μ-opioid receptor agonist that is approved for the treatment of opioid dependency. It is generally believed to be safer than methadone because of its ceiling effect on respiratory depression. As more adults in US households use buprenorphine, an increasing number of children are being exposed. We report a fatal exposure to buprenorphine in a small child that occurred ...

Satisfactory pain relief with postoperative extradural bupivacaine increases the amount of breast feeding after Caesarean section. To investigate the effect of extradural buprenorphine, we have evaluated the amount of breast feeding and the gain in infant weight for 11 days after Caesarean section in patients who received continuous extradural bupivacaine with or without buprenorphine. Extradur...
