Metabolite Identification
Common NameAlmorexant
DescriptionAlmorexant belongs to the class of organic compounds known as benzylisoquinolines. These are organic compounds containing an isoquinoline to which a benzyl group is attached. Based on a literature review a significant number of articles have been published on Almorexant. This compound has been identified in human blood as reported by (PMID: 31557052 ). Almorexant is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Almorexant 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.
