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.

5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Analgesics, Opioid

Compounds with activity like OPIATE ALKALOIDS, acting at OPIOID RECEPTORS. Properties include induction of ANALGESIA or NARCOSIS. (See all compounds classified as Analgesics, Opioid.)


Narcotic Antagonists

Agents inhibiting the effect of narcotics on the central nervous system. (See all compounds classified as Narcotic Antagonists.)


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. (See all compounds classified as Narcotics.)
