Buprenorphine HCl is a common analgesic for laboratory mice undergoing surgical procedures. The documented duration of action of buprenorphine HCl is as short as 3 to 5 h in mice, potentially necessitating readministration for continued analgesia. A long-acting buprenorphine formulation would reduce handling-associated stress and provide uninterrupted analgesia. This study used the hot-plate a...

Buprenorphine/naloxone (Suboxone) comprises the partial mu-opioid receptor agonist buprenorphine in combination with the opioid antagonist naloxone in a 4 : 1 ratio. When buprenorphine/naloxone is taken sublingually as prescribed, the naloxone exerts no clinically significant effect, leaving the opioid agonist effects of buprenorphine to predominate. However, when buprenorphine/naloxone is pare...

Background: Buprenorphine dependence is a new issue and to our knowledge no scientific papers have been published on treatment of buprenorphine dependency. The goal of this research was to characterize intravenous buprenorphine-dependent individuals with respect to socio-demographic and other background features, and to investigate the effect of methadone in the maintenance treatment of intrave...

Sensitization refers to an increase in sensitivity to the effects of a drug and is believed to play a role in the etiology of substance use disorders. Cross-sensitization has been observed between drugs from different pharmacological classes and may play a role in the escalation of drug use in polydrug-abusing populations. The purpose of this study was to examine cross-sensitization between opi...

BACKGROUND Buprenorphine is used in the treatment of opioid dependence. Due to its pharmacology, the transfer from methadone to buprenorphine may precipitate withdrawal symptoms. METHODS Methadone maintained patients with clinical indicators of stability who were seeking withdrawal from methadone were recruited from three Australian states. Patients on methadone doses between 30 and 40 mg wer...

Buprenorphine has been widely recommended for treatment of pain in rodents. We have previously documented that the recommended postoperative oral dose of buprenorphine in male Long-Evans rats, 0.5 mg/kg, is not as effective as the recommended parenteral dose of buprenorphine (0.05 mg/kg, s.c.) as an analgesic. In the series of experiments reported here, we compared: the analgesic effect of bupr...

Buprenorphine is an opioid that has a complex and unique pharmacology which provides some advantages over other potent mu agonists. We review 12 reasons for considering buprenorphine as a frontline analgesic for moderate to severe pain: (1) Buprenorphine is effective in cancer pain; (2) buprenorphine is effective in treating neuropathic pain; (3) buprenorphine treats a broader array of pain phe...

conclusions buprenorphine is more suitable for treating opiate addiction in males since it does not affect normal testicular structure and function. results stereological analysis of rat testes showed no significant effect of methadone and buprenorphine administration on the testis volume (p > 0.05). however, microscopic stud­ies of rat tissues in the methadone-administered group showed atrophi...
