Organophosphate insecticides are absorbed from all sites and act by inhibiting cholinesterases, thereby leading to the accumulation of high levels of acetylcholine. This affects the parasympathetic nervous system, muscle, and the CNS. Treatment of a patient contaminated with organophosphate insecticide will include thorough washing of the pesticide from the skin, inducing emesis or performing gastric lavage, supporting ventilation, and administering atropine followed by pralidoxime (2-PAM).
