MSH: A non-imidazole blocker of those histamine receptors that mediate gastric secretion (H2 receptors). It is used to treat gastrointestinal ulcers.,CSP: N-2-(5-dimethylamino)methyl-2- furanylmethyl thioethyl-N'-methyl-2-nitro-1,1 -ethenediamine; cimetidine analog; H2 histamine receptor antagonist used to treat gastric ulcers.,CHV: a kind of antiacid drug,CHV: a kind of antiacid drug,NCI: A member of the class of histamine H2-receptor antagonists with antacid activity. Ranitidine is a competitive and reversible inhibitor of the action of histamine, released by enterochromaffin-like (ECL) cells, at the histamine H2-receptors on parietal cells in the stomach, thereby inhibiting the normal and meal-stimulated secretion of stomach acid. In addition, other substances that promote acid secretion have a reduced effect on parietal cells when the H2 receptors are blocked.
