Levolansoprazole, the S-enantiomer of lansoprazole, is a proton pump inhibitor (PPI) that irreversibly inhibits H+/K+-stimulated ATPase pumps in parietal cells (IC50 = 5.2 μM), inhibiting gastric acid secretion and increasing intragastric pH. It also inhibits acid formation in isolated canine parietal cells (IC50 = 82 μM). Lansoprazole is an enantiomerically pure form of lansoprazole. Both (S)- and (R)-lansoprazole are pharmacologically active with similar potencies.
