Biological Activity

Lansoprazole is a H+,K+-ATPase inhibitor (IC50 = 6.3 μM) that displays antisecretory and antiulcer activity. Inhibits gastric acid secretion (IC50 = 0.09 μM for histamine-induced acid formation) and reduces gastric lesion formation induced by a variety of ulcerative stimuli. Antibacterial against Helicobacter pylori in vitro. Also blocks swelling-dependent chloride channel (ICIswell) in NIH3T3 fibroblasts. More potent than omeprazole (Cat. No. 2583).
