Rabeprazole Sulfide is an active metabolite of Rabeprazole. Rabeprazole is a proton pump inhibitor that suppresses gastric acid secretion through an interaction with (H+/K+)-ATPase in gastric parietal cells. Rabeprazole markedly inhibits the motility of H. pylori. Rabeprazole has the potential for various peptic diseases treatment[1][2].
