Metabolite Identification
Common NameAmfenac
DescriptionAmfenac, also known as amfenac sodium, belongs to the class of organic compounds known as benzophenones. These are organic compounds containing a ketone attached to two phenyl groups. In humans, amfenac is involved in the nepafenac action pathway. Amfenac is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on Amfenac. This compound has been identified in human blood as reported by (PMID: 31557052 ). Amfenac is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Amfenac 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.
