Metabolite Identification
Common NameNalmefene
DescriptionNALMEFENE-HCl belongs to the class of organic compounds known as phenanthrenes and derivatives. These are polycyclic compounds containing a phenanthrene moiety, which is a tricyclic aromatic compound with three non-linearly fused benzene. Based on a literature review a significant number of articles have been published on NALMEFENE-HCl. This compound has been identified in human blood as reported by (PMID: 31557052 ). Nalmefene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nalmefene 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.
