What type of agent is VX classified as?

VX is classified as a nerve agent, which is a type of chemical warfare agent that disrupts the normal functioning of the nervous system. Nerve agents, like VX, inhibit the enzyme acetylcholinesterase, leading to a buildup of the neurotransmitter acetylcholine in the body. This results in overstimulation of muscles, glands, and the central nervous system. Symptoms of exposure can include spasms, respiratory failure, and ultimately death if not treated promptly.

Understanding this classification helps differentiate it from other types of chemical agents. Choking agents primarily affect the respiratory system, riot control agents are intended for crowd dispersal and temporary incapacitation, and blister agents primarily cause skin and respiratory burns. Knowing that VX functions by targeting the nervous system highlights its potential for lethality and the urgency required in response efforts to protect individuals exposed to it.
