Metabolite Identification
Common NameCloxazolam, (R)-
DescriptionCloxazolam, also known as sepazon, belongs to the class of organic compounds known as 1,3-oxazolobenzo-1,4-diazepines. These are aromatic heteropolycyclic compounds containing a 1,3-oxazole ring fused to the 1,-4-diazepine moiety of a 1,4-benzodiazepine ring system. Cloxazolam is a drug which is used primarily as an anti-anxiety agent. typically used short term, and may be given as a single dose of up to 100mcg/kg to reduce anxiety and tension experienced prior to surgery. . Based on a literature review very few articles have been published on Cloxazolam. This compound has been identified in human blood as reported by (PMID: 31557052 ). Cloxazolam, (r)- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Cloxazolam, (R)- is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
