Metabolite Identification

Common Name

Lopirazepam

Description

Lopirazepam belongs to the class of organic compounds known as pyridodiazepines. These are heterocyclic compounds containing a pyridine fused to a diazepine ring. Pyridine is 6-membered ring consisting of five carbon atoms and a nitrogen atom. Diazepine is a 7-membered ring consisting of five carbon atoms and two nitrogen centers. Based on a literature review very few articles have been published on Lopirazepam. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lopirazepam is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lopirazepam 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.
