Mechanism of action

Dexlansoprazole is the active R-enantiomer of lansoprazole, a proton pump inhibitor (PPI). It binds to and inactivates the proton pump (H+/K+-ATPase) on the secretory surface of gastric parietal cells, reducing both basal and stimulated gastric acid production. The modified-release (MR) formulation provides dual-peak plasma concentrations to extend acid suppression throughout the day.
