What is Dexilant (dexlansoprazole)?
Dexilant is approved by the U.S. Food and Drug Administration (FDA) for:
- Healing of erosive esophagitis (inflammation of the esophagus)
- Maintaining healing of EE and relief of heartburn
- Treating heartburn associated with symptomatic non-erosive gastroesophageal reflux disease (GERD)
Dexilant is a proton pump inhibitor that contains the active ingredient dexlansoprazole. It reduces stomach acid secretion by binding and inhibiting the hydrogen-potassium ATPase pump (gastric proton pump) found within the parietal cells of your stomach. This allows peptic ulcers to heal as well as reduces symptoms of gastroesophageal reflux disease (GERD).
