Maintenance of healed erosive esophagitis: a randomized six-month comparison of esomeprazole twenty milligrams with lansoprazole fifteen milligrams.
OBJECTIVE
The aim was to compare esomeprazole with lansoprazole for the maintenance of healed erosive esophagitis and resolution of gastroesophageal reflux disease-related symptoms in a United States population.


METHODS
Patients who entered this double-blind, randomized, parallel-group, multicenter, maintenance trial had been treated and healed (no endoscopic evidence of erosive esophagitis) with esomeprazole 40 mg or lansoprazole 30 mg once daily (patients with Los Angeles grades C and D erosive esophagitis at baseline) or esomeprazole 40 mg (patients with Los Angeles grades A and B erosive esophagitis at baseline) and had no heartburn or acid regurgitation symptoms during the previous week. Patients were randomized to maintenance once-daily therapy with esomeprazole 20 mg (n = 512) or lansoprazole 15 mg (n = 514) for up to 6 months. Esophago-gastroduodenoscopies were done at months 3 and 6, and investigators assessed symptom severity at months 1, 3, and 6. Endoscopic/symptomatic remission was defined as no erosive esophagitis and no study withdrawal as a result of reflux symptoms.


RESULTS
The estimated endoscopic/symptomatic remission rate during a period of 6 months was significantly higher (P = .0007) for patients who received esomeprazole 20 mg once daily (84.8%) compared with those who received lansoprazole 15 mg (75.9%). Most patients had no heartburn (383/462 and 369/466) or acid regurgitation (401/462 and 400/466) symptoms at 6 months, and there were no significant differences between treatments. Both treatments were well-tolerated.


CONCLUSIONS
Esomeprazole 20 mg is more effective than lansoprazole 15 mg in maintaining endoscopic/symptomatic remission in patients with healed erosive esophagitis.
