The Utility of Nexium in Chronic Cough and Reflux Disease

Summary

The purpose of this research study is to investigate different doses of proton pump inhibitors in reducing cough symptoms felt to be associated with Gastroesophageal reflux disease (GERD). Proton pump inhibitors are medicines used to treat GERD, which work by lowering the amount of acid in the stomach. The proton pump inhibitor used in this study is called, Esomeprazole (brand name Nexium), and is already marketed for treating GERD. Patients with GERD may experience all or some of the following symptoms: stomach acid or partially digested food re-entering the esophagus (which is sometimes referred to as heartburn or regurgitation), belching and coughing. Even very small, unnoticeable amounts of rising stomach acid may cause patients to cough. Because there may be a link between chronic cough and GERD, study doctors are interested in learning if giving high-dose Nexium (40 milligrams, twice daily) will help in treating chronic cough.
