Cayman (R)-Lansoprazole; Purity- Greater Than Or Equal To 98%; Si

Lansoprazole (Item No. ) is a proton pump inhibitor that irreversibly inactivates the H⁺/K⁺-stimulated ATPase pumps in parietal cells, inhibiting gastric acid secretion and increasing intragastric pH. It is a 1:1 racemic mixture of (R)-lansoprazole and (S)-lansoprazole, both of which are pharmacologically active. (R)-Lansoprazole is an enantiomerically pure form of lansoprazole. It can inhibit acid formation in isolated canine parietal cells with an IC₅₀ value of 59 nM and inhibit the H⁺/K⁺-ATPase with an IC₅₀ value of 4.2 µM.
