Gastroesophageal Reflux Disease (GERD) is one of the most common GI conditions managed by pharmacists, affecting millions of people with symptoms ranging from mild heartburn to severe, erosive esophagitis. Effective management requires a multifaceted approach, combining patient education on lifestyle modifications with a stepwise pharmacologic strategy. As detailed in the Patient Care 4: Gastrointestinal and Renal Disorders curriculum, understanding the nuances of GERD treatment—from self-care with antacids to long-term maintenance with proton pump inhibitors (PPIs)—is a core competency for every pharmacy student.
