Galantamine inhibits its breakdown.
The basal nucleus of Meynert contains large amounts of this substance, and antibodies destroy this substance's receptors in myasthenia gravis. Galantamine inhibits its breakdown. It has ionotropic and G protein-coupled receptors called (*) nicotinic and muscarinic, respectively. This molecule is released in pre- and post-ganglionic parasympathetic neurons, as well as at the motor end plates of skeletal muscle. A deficiency of it was proposed as a cause of Alzheimer's disease, which is treated using inhibitors of its namesake esterase. For 10 points, name this neurotransmitter that mediates neuromuscular interactions.
