| Common Name | Pentazocine |

| Description | Pentazocine, also known as fortral or talwin, belongs to the class of organic compounds known as 2,6-dimethyl-3-benzazocines. These are aromatic compounds containing a 6,7-benzomorphan skeleton, which is substituted by methyl group at the 2- and 6-positions. Pentazocine is a drug which is used for the relief of moderate to severe pain. The petition was filed by Joseph L. Fink III, a pharmacist and law student at Georgetown University Law Center as part of the course Lawyering in the Public Interest. Pentazocine is a very strong basic compound (based on its pKa). Pentazocine is used primarily to treat pain, although its analgesic effects are subject to a ceiling effect. In humans, pentazocine is involved in pentazocine action pathway. In addition, animal studies have demonstrated that Pentazocine is tolerated less well subcutaneously than intramuscularly. Pentazocine is a potentially toxic compound. U.S. testing was conducted between 1961 and 1967. |
