Valpin (Anisotropine Methylbromide) is a small molecule drug developed by ENDO PHARMS, targeting the muscarinic acetylcholine receptor M1. It is classified as an octatropine methylbromide and was approved by the FDA in 1962 for the treatment of gastric and peptic ulcers. As an off-patent medication, it is available as a generic option. Key safety considerations include its relatively low bioavailability of 18%. Valpin is no longer under patent protection, allowing multiple generic manufacturers to produce the medication.
