<prompt> Mechanism of action of atropine in treatment of organophophate poisoning is?It inhibits secretion of acetylcholineIt is reactivator of acetylcholine esterase enzymeIt has antimuscarinic activityIt is agonist of acetylcholine receptors  <response>: Organophosphates AcHE inhibitors acetylcholine cannot be broken Level of acetyl choline increases Stimulate nicotinic muscarinic receptors Over activity of M1- acidity M2- bradycardia M3- bronchoconstriction, secretion, diarrhea urination Atropine is DOC for organophosphate poisoning But atropine doesnt block the nicotinic receptors muscle weakness
