Buprenorphine

Buprenorphine is a slow-onset, long-acting synthetic opiate derived from thebaine, an alkaloid of the poppy Papaver somniferum. The United States Food and Drug Administration does not currently approve buprenorphine for veterinary use, but it is common practice to use this drug in animal patients.
