[Pharmacological Actions]
This product is a benzimidazole compound. After oral absorption, it is translocated to the gastric mucosa and converted into an active metabolite under acidic conditions. This active metabolite specifically inhibits the H+/K+-ATPase system in gastric parietal cells, blocking the final step of gastric acid secretion. This product inhibits basal gastric acid secretion and stimulated gastric acid secretion in a dose-dependent manner. This product has no antagonistic effect on cholinergic and amine H2 receptors.
