AGA -- Despite daily use of doctor-recommended proton pump inhibitors (PPIs) to control gastroesophageal reflux disease (GERD) symptoms, nearly 40 percent of patients who take them continue to experience breakthrough, which is a return of GERD symptoms, such as acid regurgitation and heartburn. These breakthrough symptoms lead more than half of GERD sufferers to use over-the-counter (OTC) remedies, according to a survey recently conducted by the American Gastroenterological Association (AGA) Institute.
