Overview

Metrifonate (INN) or trichlorfon (USAN) is an irreversible organophosphate acetylcholinesterase inhibitor.[1] It is a prodrug which is activated non-enzymatically into 2,2-dichlorovinyl dimethyl phosphate (DDVP).

It is used as an insecticide.

It can be used to treat schistosomiasis caused by Schistoma haematobium but is no longer commercially available.[2]

It has been proposed for use in treatment of Alzheimer’s disease, but use for that purpose is not currently recommended.[3]
