Reflux esophagitis is a frequent and chronic disease. Impairment of the quality of life by the reflux symptoms and the risk of complications are the most important indications for a long-term treatment. The base of the treatment of reflux esophagitis is the inhibition of the gastric acid secretion with proton pump inhibitors (PPI) or by H2-receptor antagonist. In general, PPI's are more efficient in the treatment of refluxesophagitis as compared to H2-receptor antagonists blockers regarding the relieve of symptoms and the healing of erosive esophageal lesions. The use of an antacids and procinetics in the long-term treatment is not indicated. The treatment strategy depends on the severity of the symptoms and the esophageal lesions. Patient with mild esophagitis can be treated either with H2-receptor antagonists or with PPI's on demand or continuous. In the case of severe esophagitis, a long-term treatment with PPI's is indicated to avoid complications. Recurrence of esophagitis during a long-term therapy should be treated by PPI's. After healing the long-term treatment should be adapted either by increasing the given dose of the medicament or by a switch to more effective medicaments in acid suppression.
