Is It Time for Noncontinuous Therapy for Gastroesophageal Reflux Disease?
Abstract
Gastroesophageal reflux disease (GERD) is a chronic disorder characterized by the reflux of gastric contents into the esophagus, leading to symptoms and potential long-term complications such as Barrett esophagus and esophageal adenocarcinoma. Currently, there are various medical, endoscopic, and surgical therapeutic strategies for GERD. However, proton pump inhibitors (PPIs), which effectively suppress acid secretion but require daily administration, remain the mainstay of treatment. Noncontinuous therapy for GERD includes on-demand and different variations of intermittent administration of antireflux medication. Attributes that make an antireflux medication a good candidate for noncontinuous therapy for GERD include potent acid suppression, rapid effect, durability of antisecretory effect, and flexibility of administration. Noncontinuous therapy for GERD is appealing to patients because it is convenient, reduces cost, and alleviates concerns about complications of long-term PPI use. Patients with nonerosive esophageal reflux disease or low-grade erosive esophagitis who have episodic heartburn are probably best suited for such treatment. Although PPIs have been shown to be efficacious as on-demand or intermittent therapy for GERD, their usefulness as on-demand treatment for episodic heartburn has been limited by their slow maximal effect on intragastric acid secretion. In contrast, potassium-competitive acid blockers (P-CABs) demonstrate the pharmacokinetic and…
