Isopropamid (ISOPROPAMIDE)

GSK · FDA-approved approved Small molecule Quality 30/100

Isopropamide, also known as ISOPROPAMIDE, is a small molecule drug developed by GlaxoSmithKline that targets the muscarinic acetylcholine receptor M1. It was approved by the FDA in 1957 for the treatment of peptic ulcers. As an off-patent medication, it is no longer protected by active patents, and there are currently no generic manufacturers. Isopropamide works by stimulating the muscarinic receptors in the stomach, which helps to increase the movement of food through the digestive system and reduce stomach acid production. It is a medication that has been used for many years to treat peptic ulcers.
