In pharmacology, buprenorphine is "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."[1]
History
In the United States, an injectable version was approved with a New Drug Application (NDA) by the FDA in 1981.[2] An oral/sublingual version (Subutex) was approved with a New Drug Application (NDA) by the FDA in 2002.[3] An oral/sublingual version combined with naloxone (Suboxone) was approved with a New Drug Application (NDA) by the FDA in 2002.[4]
An injectable generic version was approved with a Abbreviated New Drug Application (ANDA) in 1996.[5]
Pharmacology
Metabolism
Buprenorphine is metabolized by cytochrome P-450, specifically the .[6]
Uses
Opiate withdrawal
Buprenorphine is more effective than clonidine or lofexidine and possibly more effective than methadone for treating opiate withdrawal according to a meta-analysis by the Cochrane Collaboration.[7]
Opiate dependence
Although buprenorphine–naloxone may be less effective than methadone[8], it has more predictable dosing[9], and can be prescribed by qualifying office-based physicians.[10]
Veterinary medicine
Burprenorphine does not cause the hyperexcitation in cats that classically has been associated with pure agonists, and provides analgesia.
