Pyridostigmine is a reversible acetylcholinesterase inhibitor of the carbamate class that prevents the hydrolysis of acetylcholine at cholinergic synapses, increasing the concentration and duration of action of acetylcholine at the neuromuscular junction and parasympathetic effector organs. It is primarily used for the symptomatic treatment of myasthenia gravis and has also been investigated as a pretreatment against nerve agent exposure.
