<prompt> Cholinesterase activators are useful for treatment of which poisoning ?ParaquatParathionCarbamatesOrganochlorocompounds  <response>: Ref:KD Tripathi pharmacology 6th edition page.no: 99,105 Cholinesterase reactivators like Oximespralidoxime are used to restore neuromuscular transmission in case of organophosphate anti-ChE poisoning. Organophosphates are Dyflos DFP Echothiophate Parathion, Malathion DiazinonTIK-20 Tabun, Sarin, Soman. Pralidoxime attaches to anionic site of enzyme which remains unoccupied in presence of OP inhibitors. Its Oxime end react with phosphorus atom attached to the esteratic site. Oxime-Phosphonate so formed diffuses away leaving the reactivated ChE.
