Dexilant Treatment in Gastrointestinal Reflux Disease (GERD Related Non Cardiac Chest Pain

The Effect of Dexilant Treatment on Esophageal Hypersensitivity in GERD Related Non Cardiac Chest Pain Patients

The purpose of this study is to investigate a new treatment for non-cardiac chest pain (NCCP) related to gastrointestinal reflux disease (GERD), called Dexilant. The investigators would like to test its effectiveness in treating NCCP.

The patient will undergo esophageal balloon distention testing (EBDT) before and after taking the new treatment for one month (Dexilant). EBDT evaluates the sensation and mechanical properties of the esophagus. A catheter with a deflated balloon is placed through the mouth and into the esophagus and the balloon is inflated with water. ECG and labs will be done throughout the study as a measurement of safety.

Inclusion Criteria:

1. Aged 18-75 years
2. NERD, or GERD LA Class A-B (endoscopy)
3. Subjects with positive pH testing
4. At least one episode of chest pain a week in the past month
5. Previous negative cardiac evaluation (EKG ± stress test ± coronary angiogram)
6. Negative esophageal evaluation for a motility disorder (Nutcracker esophagus, achalasia)

Exclusion Criteria:

1. Subjects requiring narcotics or other pain medications, Subjects with known LA class C-D, Barrett's esophagus or peptic stricture on endoscopy
