How does mestinon (pyridostigmine) help myasthenia gravis?

See below: In myesthenia gravis, the body produces antibodies to the a type of muscle receptor that uses acetylcholine, a neurotransmitter responsible for muscle contraction. These antibodies prevent electrical signals from getting to the muscles which causes weakness. Mestinon (pyridostigmine) slows down the breakdown of acetylcholine in the body so that more acetylcholine is around to interact with the receptors.
