Pirenzepine (Gastrozepin), an M1 selective antagonist, is used in the treatment of peptic ulcers, as it reduces gastric acid secretion and reduces muscle spasm. It is in a class of drugs known as muscarinic receptor antagonists - acetylcholine being the neurotransmitter of the parasympathetic nervous system which initiates the rest-and-digest state (as opposed to fight-or-flight), the result being an increase in gastric motility and digestion.[1] It has no effects on the brain and spinal cord as it cannot diffuse through the blood–brain barrier.

Pirenzepine has been investigated for use in myopia control.[2][3]
