Advances in Gastroesophageal Reflux Disease Management: Exploring the Role of Potassium-Competitive Acid Blockers and Novel Therapies
Abstract
Gastroesophageal reflux disease (GERD) is a prevalent chronic gastrointestinal disorder that affects a substantial proportion of the global population. It is characterized by the extensive backward flow of stomach contents into the esophagus, leading to troublesome symptoms and potential complications. Proton pump inhibitors (PPIs) have long been the cornerstone of pharmacological treatment for GERD, effectively suppressing gastric acid secretion. However, a substantial subset of patients, referred to as PPI-refractory GERD, experience inadequate symptom control despite optimal PPI therapy. GERD significantly impacts patients' quality of life, affecting domains, such as vitality, pain, and physical functioning. Consequently, there is an urgent need for alternative therapeutic strategies and novel pharmacologic agents to provide more effective, long-term relief. Emerging treatment options include potassium-competitive acid blockers (PCABs) like vonoprazan, which offer more potent and sustained inhibition of gastric acid secretion compared to traditional PPIs. Additionally, prokinetic agents such as itopride have gained attention due to their potential to improve GERD symptoms by enhancing gastrointestinal motility and accelerating gastric emptying. This article reviews the mechanisms of action, clinical efficacy, and potential of these novel therapeutic approaches in improving patient outcomes in GERD management. With the growing prevalence of PPI resistance and side effects,…
