Prevention of nerve agent poisoning

The prevention of nerve agent poisoning refers to medical pretreatment strategies deployed before potential exposure to organophosphorus chemical warfare agents—such as soman, sarin, tabun, or VX—to mitigate life-threatening toxicity

These agents irreversibly inhibit acetylcholinesterase throughout the central, peripheral, and autonomic nervous systems, provoking excessive acetylcholine accumulation at muscarinic and nicotinic receptors This hyperstimulation triggers a rapid, life-threatening cholinergic crisis marked by copious bronchorrhea, bronchospasm, neuromuscular weakness, fasciculations, seizures, and fatal respiratory failure

Pretreatment typically targets individuals at imminent risk, such as military personnel or emergency response teams, aiming to protect a fraction of acetylcholinesterase enzymes from permanent covalent bonding and subsequent enzymatic "aging"
