Mechanism of Action
Omeprazole is a substituted benzimidazole gastric antisecretory agent and is also known as PPI. It blocks the final step in gastric acid secretion by specific inhibition of H+/K+ ATPase enzyme system present on the secretory surface of the gastric parietal cell. Both basal and stimulated acid are inhibited.
