Identification

Generic Name
Fenthion
DrugBank Accession Number
DB11412
Background

Fenthion is an organothiophosphate drug used as an insecticide, avicide, and acaricide. Its mode of action is explained by cholinesterase enzyme inhibition, which is similar to other organophosphates. Fenthion is listed as a restricted use compound by the United States Environmental Protection Agency due to its potential to cause cholinesterase inhibition in humans and animals.
