Quizplus · Accepted Answer

Omeprazole (Prilosec) is a proton pump inhibitor (PPI) that works by inhibiting the hydrogen-potassium ATPase pump on the surface of gastric parietal cells, thereby reducing gastric acid secretion. This action is different from histamine-2 receptor antagonists, which block histamine-2 receptors to reduce acid production. Omeprazole does not directly affect the gastric mucus layer or the mucosa of the trachea.
