Excretion is usually as products of hydrolysis in the urine. Mechanism and mode of action of organophosphate poisoning: It acts on the myoneural junction and the synapses of ganglia and interferes with the activity of enzyme cholinesterase and inhibits its action on acetylcholine.

While onset of symptoms is often within minutes to hours, some symptoms can take weeks to appear. 814701-overview Diseases & Conditions,2002 Organophosphate poisoning is poisoning due to organophosphates (OPs). Resolution of symptoms and a rising acetylcholinesterase level indicate response to therapy.In military or disaster scenarios, atropine and an oxime are combined in “autoinjectors.” Pralidoxime is discussed here, but in other parts of the world, including the United States, other oximes are used, the most frequent being obidoxime.
