BACKGROUND Fentanyl is a potent mu-opioid receptor agonist that is widely used for the treatment of severe chronic pain. Discontinuation of fentanyl administration has been shown to induce a negative emotional state. OBJECTIVE The aim of the present studies was to investigate the effects of the partial mu-opioid receptor agonist buprenorphine on the negative emotional state associated with precipitated and spontaneous fentanyl withdrawal in rats. METHODS Fentanyl and saline were chronically administered via osmotic minipumps. A discrete-trial intracranial self-stimulation procedure was used to provide a measure of brain reward function. Somatic signs were recorded from a checklist of opioid abstinence signs. RESULTS Naloxone induced a deficit in brain reward function in rats chronically treated with fentanyl. Buprenorphine dose-dependently prevented the naloxone-induced deficit in brain reward function. Discontinuation of fentanyl administration was also associated with a deficit in brain reward function. After explantation of the minipumps, the administration of buprenorphine induced a potentiation of brain reward function in the fentanyl-withdrawing rats, but did not affect brain reward function of saline-treated control rats. Buprenorphine prevented the somatic withdrawal signs associated with spontaneous fentanyl withdrawal and attenuated the somatic signs associated with precipitated fentanyl withdrawal. CONCLUSIONS Buprenorphine prevents affective and somatic fentanyl withdrawal signs. Moreover, buprenorphine is rewarding in rats previously exposed to fentanyl, but not in opioid-naïve rats. This pattern of results suggests that buprenorphine may be an effective treatment for the anhedonic-state associated with fentanyl withdrawal, but further study of buprenorphine's abuse potential is warranted.

D009294 Narcotics Agents that induce NARCOSIS. Narcotics include agents that cause somnolence or induced sleep (STUPOR); natural or synthetic derivatives of OPIUM or MORPHINE or any substance that has such effects. They are potent inducers of ANALGESIA and OPIOID-RELATED DISORDERS. Analgesics, Narcotic,Narcotic Analgesics,Narcotic,Narcotic Effect,Narcotic Effects,Effect, Narcotic,Effects, Narcotic
D002047 Buprenorphine A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use. 6029-M,Buprenex,Buprenorphine Hydrochloride,Buprex,Prefin,RX-6029-M,Subutex,Temgesic,Temgésic,6029 M,6029M,Hydrochloride, Buprenorphine,RX 6029 M,RX6029M

D005283 Fentanyl A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist.
