Protonix vs. Dexilant Drug Summary
Protonix
Protonix (pantoprazole) is a proton pump inhibitor used to heal and maintain healing of erosive esophagitis from GERD and to control pathological hypersecretory conditions like Zollinger-Ellison syndrome. It comes as a delayed-release tablet, oral suspension, or IV injection, taken once or twice daily depending on the condition.
Dexilant
Dexilant (dexlansoprazole) is a proton pump inhibitor used to heal erosive esophagitis, maintain that healing, and relieve heartburn from non-erosive GERD. It is taken as a single once-daily capsule that uses a dual-release design, so dosing does not depend on meal timing.
