Terms & Properties

Preferred Name: Omeprazole

Definition: A benzimidazole with selective and irreversible proton pump inhibition activity. Omeprazole forms a stable disulfide bond with the sulfhydryl group of the hydrogen-potassium (H+ - K+) ATPase found on the secretory surface of parietal cells, thereby inhibiting the final transport of hydrogen ions (via exchange with potassium ions) into the gastric lumen and suppressing gastric acid secretion. This agent exhibits no anticholinergic activities and does not antagonize histamine H2 receptors.

NCI-GLOSS Definition: A drug that inhibits gastric acid secretion.

Display Name: Omeprazole

Label: Omeprazole
