Description
Summary:Summary Aim:  To assess the efficacy of the 8‐week therapy with esomeprazole 40 mg vs. pantoprazole 40 mg for healing erosive oesophagitis (EE) as part of a management study. Methods:  Patients had a history of gastro‐oesophageal reflux disease symptoms (≥6 months) and had suffered heartburn on at least 4 of the 7 days preceding enrolment. Endoscopies were performed to grade EE severity using the Los Angeles (LA) classification system at baseline, 4 and 8 weeks (if unhealed at 4 weeks). Heartburn severity was recorded by patients on diary cards. The primary end point was healing of EE by week 8 of treatment. Results:  Of 3170 patients randomized, the intent‐to‐treat population consisted of 3151 patients (63% male, mean age: 50.6 years, 27%Helicobacter pylori‐positive). Esomeprazole 40 mg healed a significantly greater proportion of EE patients than pantoprazole 40 mg at both 4 weeks (life table estimates: esomeprazole 81%, pantoprazole 75%, P < 0.001) and 8 weeks (life table estimates: esomeprazole 96%, pantoprazole 92%, P < 0.001). The median time to reach sustained heartburn resolution was 6 days in patients receiving esomeprazole and 8 days with pantoprazole (P < 0.001). Conclusion:  Esomeprazole 40 mg is more effective than pantoprazole 40 mg for healing EE and providing resolution of associated heartburn.
