H2 blockers
Gastric secretion inhibitors
H2 blockers are medications that reduce stomach acid production by blocking histamine receptors in the stomach lining.
They treat heartburn, acid reflux, and ulcers.
Common examples include famotidine (Pepcid) and ranitidine (formerly Zantac).
The H2 refers to a specific type of histamine receptor, distinguishing these drugs from antihistamines that block H1 receptors for allergies.
