What is Dexlansoprazole for?

Gastroesophageal Reflux Disease (GERD) is a disease whose gastric content flows back to the esophagus. GERD may be triggered after meals, especially after eating spicy food, oily food, or alcoholic drinks. Dexlansoprazole, a proton pump inhibitor,  strongly inhibits the secretion of gastric acid in the stomach by blocking the “proton pumps” in stomach cells.

How to use it?

Dexlansoprazole is available in delayed-release capsules for oral use for longer duration of action. It can be taken with or without food. Do not crush, chew or open the capsules unless instructed.
