It belongs to the class of histamine H2-receptor antagonists and works by blocking the action of histamine on the H2 receptors in the stomach, thereby reducing the amount of acid produced.
Used to treat peptic ulcers, gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome, and heartburn.
