| Common Name | Afoxolaner |

| Description | Afoxolaner, also known as A1443 or AH252723, belongs to the class of organic compounds known as naphthalenecarboxamides. Naphthalenecarboxamides are compounds containing a naphthalene moiety, which bears a carboxylic acid amide group at one or more positions. Naphthalene is a bicyclic compound that is made up of two fused benzene rings. Based on a literature review very few articles have been published on Afoxolaner. This compound has been identified in human blood as reported by (PMID: 31557052 ). Afoxolaner is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Afoxolaner 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. |
