Metabolite Identification
Common NamePimavanserin
DescriptionPimavanserin belongs to the class of organic compounds known as phenol ethers. These are aromatic compounds containing an ether group substituted with a benzene ring. Based on a literature review a significant number of articles have been published on Pimavanserin. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pimavanserin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Pimavanserin 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.
