An update on the available treatments for non-erosive reflux disease

Non-erosive reflux disease is defined as the presence of troublesome reflux symptoms, such as heartburn and regurgitation, in the absence of endoscopically-visible damage of the oesophageal mucosa. In comparison with erosive oesophagitis, non-erosive reflux disease is the most common clinical manifestation of gastro-oesophageal reflux disease. Pathophysiologically, it is not a homogeneous disease as only approximately two-thirds of patients have truly acid-related symptoms. This explains the fact that patients with non-erosive reflux disease consistently show a poorer response to proton pump inhibitor treatment than patients with erosive oesophagitis. Nevertheless, profound acid inhibition by proton pump inhibitors is the recommended first-line treatment in patients suffering from this condition, both in the initial phase and for long-term care. Non-responders to proton pump inhibitor therapy should be subjected to a thorough examination and treated on an individual basis. Emerging data on the long-term course of reflux disease under routine clinical care have led to the adoption of new therapeutic strategies that would have been unthinkable only a few years ago.
