OBJECTIVES: To compare the efficacy and tolerability of pantoprazole 20 mg once daily with that of esomeprazole 20 mg once daily for 6 months as maintenance therapy in patients with previously healed gastroesophageal reflux disease. METHODS: In an initial open-label acute phase, outpatients with endoscopically confirmed gastroesophageal reflux disease (Los Angeles grades A-D) received pantoprazole 40 mg once daily for 4 or 8 weeks. Those healed (defined as the absence of esophagitis, and 'no' or 'mild' heartburn and acid regurgitation) were randomized in the double-blind manner for maintenance therapy with pantoprazole 20 mg once daily or esomeprazole 20 mg once daily for 6 months. RESULTS: In the acute healing phase, 1452 patients were recruited to receive pantoprazole 40 mg once daily. Healing success was 91% (intent-to-treat analysis). A total of 1303 patients entered the maintenance phase of the study. Pantoprazole 20 mg once daily and esomeprazole 20 mg once daily were equally effective at maintaining patients in remission; 84 and 85% of pantoprazole and esomeprazole recipients remained in combined endoscopic and symptomatic remission at 6 months (intent-to-treat analysis). The confidence interval of the difference was (-5.7; +infinity), showing that pantoprazole is as effective as esomeprazole with a noninferiority margin of 5.8%. Combined endoscopic and symptomatic remission was independent of Helicobacter pylori status. Both treatments were well tolerated and safe. CONCLUSION: Treatment with pantoprazole 20 mg once daily or esomeprazole 20 mg once daily provides similarly effective and well-tolerated maintenance of previously healed gastroesophageal reflux disease irrespective of baseline H. pylori status.
