Local Phase IV, Gastroesophageal Reflux Disease (GERD) Sleep Study US

Relief of nighttime heartburn on patient's last 7 days in the study. Relief was defined as a daily diary card response of "none" or 0, on at least 6 of 7 days, allowing for one "mild" or 1 response. Diary card scale (none, mild, moderate, severe).
