Mechanism of action

This results in a decrease in gastric acid production, which can help alleviate symptoms of gastroesophageal reflux disease (GERD) and other conditions associated with excessive acid production. Lansoprazole works by covalently binding to the H+/K+ ATPase enzyme, preventing it from pumping protons into the gastric lumen and thereby reducing gastric acid secretion.
