Biochem/physiol Actions

Pyridostigmine bromide inhibits acetylcholine esterase and is membrane impermeable. It is used as a preventive medicine in chemical warfare. Pyridostigmine bromide is a carbamate compound comprising quaternary amine structure. It displays low absorption at the gastrointestinal tract. Sustained release of pyridostigmine is recommended for improving its bioavailability in treating myasthenia gravis.
Acetylcholinesterase inhibitor.
