Lansoprazole ≥98%

Lansoprazole is a ATP4A (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 (ICI swell) in NIH3T3 fibroblasts. Lansoprazole is more potent than omeprazole
