What is Mestinon?
Trihexyphenidyl: The muscarinic actions of pyridostigmine can antagonize the antimuscarinic actions of trihexyphenidyl. Trimipramine: Tricyclic antidepressants may antagonize some of the effects of parasympathomimetics, such as pyridostigmine, due to their anticholinergic activity. Mechanism of Action: Pyridostigmine exerts its effects by competing with acetylcholine for its binding site on acetylcholinesterase. By interfering with acetylcholine enzymatic destruction, pyridostigmine potentiates the action of acetylcholine on both the skeletal muscle nicotinic receptor and the GI tract muscarinic receptor.
Pyridostigmine also can stimulate cholinergic responses in the eyes causing miosis if directly applied. Different muscle groups exhibit different levels of response to anticholinesterase agents, and doses that produce stimulation of one muscle group can cause weakness, through overdose, in another.
There is also some evidence that they have a direct action on skeletal muscle. Oral doses of pyridostigmine are poorly absorbed, and there is considerable patient variation in response.
