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 an organic thiophosphate, a member of phosphocholines and a quaternary ammonium ion."}]
