Metabolite Identification
Common NameFlubendazole
DescriptionFlubendazole, also known as R 17,889, belongs to the class of organic compounds known as benzophenones. These are organic compounds containing a ketone attached to two phenyl groups. Flubendazole is a moderately basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Flubendazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Flubendazole 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.
