Introduction: Gastroesophageal reflux disease (GERD) is a chronic disease of the esophagus characterized by the regurgitation of stomach contents into the esophagus, causing troublesome symptoms and/or complications. Among patients with GERD, around 30% of patients have visible mucosal damage, while 70% have normal esophageal mucosa. Accordingly, the optimal pharmacological treatment of GERD should address different disease manifestations, including symptoms, the mucosal damage when present, and possible chronic complications, including strictures, Barrett's esophagus, and esophageal adenocarcinoma.
Areas covered: Available medical treatments for GERD include proton pump inhibitors (PPIs), potassium-competitive acid blockers (PCABs), histamine receptor antagonists (H2-RAs), prokinetics, and mucosal protectants, such as alginates, hyaluronic acid/chondroitin-sulfate, and poliprotect. Each compound has its own advantages and disadvantages, and knowledge of expected benefits and tips for their use is paramount for the success of treatment. In addition, the appropriateness of indications for initiating treatment is also crucial to achieve positive results when managing GERD patients.
Expert opinion: PPIs, PCABs, H2-RAs, prokinetics, and mucosal protectants can all be used in patients with GERD, but careful assessment of patients' characteristics as well as advantages and disadvantages of each therapeutic compound is essential to ensure successful treatment of GERD.
