What is Echothiophate?

Plain description, key identifiers and synonyms

Ecothiopate is the phosphorothioate obtained by formal condensation of diethyl phosphate with N,N,N-trimethyl-2-sulfanylethanaminium. An irreversible acetylcholinesterase inhibitor, its iodide salt is used an ocular antihypertensive in the treatment of open-angle glaucoma, particularly when other drugs have proved inadequate. It has a role as an EC 3.1.1.8 (cholinesterase) inhibitor and a miotic. It is a quaternary ammonium ion, a member of phosphocholines and an organic thiophosphate.

Echothiophate is a pharmaceutical drug.
