[Pharmacology and Toxicology]
This product is a benzimidazole compound. After oral absorption, it is translocated to the gastric mucosa and, under acidic conditions, is converted into an active metabolite. This active metabolite specifically inhibits the H+/water/K+/ATPase system in gastric parietal cells, blocking the final step of gastric acid secretion. This product inhibits basal and stimulated gastric acid secretion in a dose-dependent manner. It does not antagonize cholinergic or amine H2 receptors.
