Mechanism of Action

Famotidine competitively blocks histamine H2-receptors thus reducing basal, nocturnal and stimulated gastric acid secretion. Pepsin secretion is reduced resulting in decreased peptic activity. It effectively heals duodenal and gastric ulcers and prevents recurrence. Absorption: Readily but incompletely absorbed from the GI tract; peak plasma concentrations after 1-3 hr (oral). Distribution: Enters the breast milk. Protein-binding: 15-20%. Metabolism: Hepatic (small proportion); converted to famotidine S-oxide. Excretion: Urine (as unchanged) within 24 hr; 2.5-3.5 hr (elimination half-life).
