Mechanism of action

Unlike proton pump inhibitors (PPIs) that irreversibly bind the H+/K+-ATPase, linaprazan competitively blocks potassium binding to the pump, allowing for faster onset and offset of acid suppression. This mechanism may provide more consistent 24-hour pH control and potentially faster healing of acid-related lesions. The glurate salt formulation is designed to improve bioavailability and tolerability.
