Metabolite Identification
Common NameHalazepam
DescriptionHalazepam, also known as paxipam, belongs to the class of organic compounds known as 1,4-benzodiazepines. These are organic compounds containing a benzene ring fused to a 1,4-azepine. Halazepam was used for the treatment of anxiety. Halazepam is a drug. Halazepam is a moderately basic compound (based on its pKa). Halazepam is a potentially toxic compound. However, Halazepam is not commercially available in the United States because it was withdrawn by its manufacturer for poor sales. Halazepam was invented by Schlesinger Walter in the U.S. Gastrointestinal side effects have also been reported including dry mouth and nausea.Pharmacokinetics and pharmacodynamics were listed in Current Psychotherapeutic Drugs published in June 15, 1998 as follows:Halazepam is classified as a schedule 4 controlled substance with a corresponding code 2762 by the Drug Enforcement Administration (DEA). Adverse effects include drowsiness, confusion, dizziness, and sedation. Halazepam is a benzodiazepine derivative that was marketed under the brand names Paxipam in the United States, Alapryl in Spain, and Pacinone in Portugal. It was marketed as an anti-anxiety agent in 1981.
