The compound is a cholinesterase inhibitor with all the pharmacologic actions of acetylcholine, both the muscarinic and nicotinic types. Cholinesterase inactivates acetylcholine. Like neostigmine, MYTELASE suppresses cholinesterase but has the advantage of longer duration of action and fewer side effects on the gastrointestinal tract. The longer duration of action also results in more even strength, better endurance, and greater residual effect during the night and on awakening than is produced by shorter-acting anticholinesterase compounds.
