Witryna1 lip 2024 · Organophosphate poisoning (acetylcholinesterase (AChE) inhibitors) Acetylcholinesterase is a synaptic enzyme which modulate nerve impulses by breaking down the CNS- central nervous system neurotransmitter acetylcholine (ACh). WitrynaOrganophosphate (OP) and carbamate (CM) pesticides produce toxicity by inhibiting acetylcholinesterase (AChE) activity. Inactivation of AChE results in excessive ACh accumulation at the synapses and at neuromuscular junctions leading to an overstimulation of the muscarinic and nicotinic ACh receptors.
