Common Name | Favipiravir |
---|
Description | Favipiravir, also known as avigan or favipira, belongs to the class of organic compounds known as pyrazinecarboxamides. Pyrazinecarboxamides are compounds containing a pyrazine ring which bears a carboxamide. Based on a literature review a significant number of articles have been published on Favipiravir. This compound has been identified in human blood as reported by (PMID: 31557052 ). Favipiravir is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Favipiravir 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. |
