Maintenance therapy of gastroesophageal reflux disease.

Abstract

The aims of treatment of gastroesophageal reflux disease (GERD) are to cure mucosal breaks, control symptoms, and prevent complications (e.g. stricture, Barrett's esophagus, and esophageal adenocarcinoma). Proton pump inhibitors (PPIs) are known to be the best drugs to cure esophagitis; however, a highrecurrence rate of about 80% was described after the completion of initial therapy. Regretfully, not so many physicians perform maintenance therapy in clinical practice. Histamine H2 receptor antagonists have an insufficient effect in maintenance therapy compared with PPIs; therefore, they could be prescribed for mild reflux esophagitis. Several clinical trials have been conducted to investigate the efficacy of continuous PPI administration maintenance therapy for GERD. Among these trials, recent large-scale studies showed that esomeprazole was equal to or superior to other kinds of PPIs. On the other hand, on-demand PPI studies have been conducted, mainly in patients with nonerosive reflux disease or uninvestigated GERD;however, this strategy was less effective than continuous therapy in many studies. Because on-demand therapy is less expensive, it is worth confirming this strategy in further studies. Studies of maintenance therapy with investigations conducted for as long a period as 5 years have described that PPI maintenance therapy could be considered as effective, safe, and well tolerated.
