Narcotics Awareness...Buprenorphine Explained

Butorphanol While butorphanol can be made from thebaine, it is usually manufactured synthetically. It was initially available in injectable formulations for human (StadolŪ) and veterinary (TorbugesicŪ and TorbutrolŪ) use. More recently, a nasal spray (Stadol NSŪ) became available, and significant diversion and abuse of this product led to the 1997 control of butorphanol in Schedule IV of the CSA. Butorphanol is a clear example of a drug gaining favor as a drug of abuse only after it became available in a form that facilitated its mode of administration (nasal spray v. injection).
