Famotidine
Famotidine 40 mg is a histamine H2-receptor blocker (H2 blocker) that works by reducing the amount of acid your stomach produces. It is commonly used to treat and prevent conditions related to excess stomach acid.
Share:
Famotidine blocks histamine H2 receptors in the stomach lining, which stops the signal that tells the stomach to produce acid. This helps reduce irritation and allows healing of ulcers or inflammation.
