    Product Description

    (S)-Lansoprazole is a proton pump inhibitor that irreversibly inhibits H+/K+-stimulated ATPase pumps in parietal cells (IC50 = 5.2 µM), inhibiting gastric acid secretion and increasing intragastric pH.1 It also inhibits acid formation in isolated canine parietal cells (IC50 = 82 µM). (S)-Lansoprazole is an enantiomerically pure form of lansoprazole (Item No. 13627). Both (S)- and (R)-lansoprazole (Item No. 18235) are pharmacologically active with similar potencies.1

    WARNING This product is not for human or veterinary use.
