Used primarily in the treatment of peptic ulcers and gastroesophageal reflux disease (GERD), this compound acts as a histamine H2-receptor antagonist, reducing gastric acid secretion. It helps relieve symptoms such as heartburn and indigestion and promotes healing of the esophageal and stomach lining. Due to its acid-suppressing effects, it is also employed in the management of Zollinger-Ellison syndrome and other conditions involving excessive stomach acid production. The drug is typically administered orally and offers a well-tolerated option for short-term and long-term acid control.
