H2 Receptor Antagonists are medications that work by inhibiting the interaction between histamine and H2 receptors in the stomach, thereby reducing gastric acid secretion, pepsin output, and acid volume.

Histamine H2 receptor antagonists (H2RAs) competitively inhibit H2 receptors, resulting in a significant reduction in gastric acid secretion.

Aug 7, 2023 · H2 receptor antagonists H2RAs are acid-suppressing agents that reversibly and competitively inhibit histamine binding at H2 receptors on gastric parietal cells to reduce hydrogen …
