Application
Pyridostigmine Bromide: A Reversible Cholinesterase Inhibitor
Pyridostigmine bromide is a reversible cholinesterase inhibitor which inhibits the hydrolysis of acetylcholine (ACh) by competitive reversible binding to acetylcholinesterase (AChE). Pyridostigmine bromide is not through to enter the brain in significant amounts, and mainly activates peripheral cholinergic nervous system by increasing the concentration of ACh in the nerve through reversible inhibition of its hydrolysis by AChE. Pyridostigmine bromide is used for symptomatic treatment of myasthenia gravis and has been applied as a prophylaxis against nerve agents. (The product is for research purpose only.)
