Core Tip
Core tip: In China, physicians tend to perform endoscopies on patients presenting with typical symptoms of gastro-esophageal reflux disease, such as reflux or heartburn. If endoscopy findings are negative, patients are usually diagnosed with chronic gastritis rather than non-erosive reflux disease (NERD) and treated with a 2-wk course of proton pump inhibitors (PPIs). We compared symptom control rates when patients were treated with a 2-wk course of PPIs vs an 8-wk course, as recommended for patients with NERD. In this multicenter, randomized, open-label study, the 8-wk PPI regimen provided marginally better symptom control and relief rates than the 2-wk regimen, with a similar safety profile.
