Background and Aim:  Rabeprazole has a faster onset of antisecretory activity than omeprazole and lansoprazole. The aim of the present study was to clarify whether there is any difference in the speed of symptom relief in patients with reflux esophagitis following the administration of these three proton pump inhibitors (PPI).

Methods:  Eighty-five patients with erosive reflux esophagitis were randomized to receive 8 weeks of 20 mg of omeprazole (n = 30), 30 mg of lansoprazole (n = 25), or 20 mg of rabeprazole (n = 30) once a morning. Daily changes in heartburn and acid reflux symptoms in the first 7 days of administration were assessed using a six-point scale (0: none, 1: mild, 2: mild–moderate, 3: moderate, 4: moderate–severe, 5: severe).

Results:  The mean heartburn score in patients administered rabeprazole decreased more rapidly than those given the other PPI. Complete heartburn remission also occurred more rapidly in patients administered rabeprazole (compared with omeprazole: P = 0.035, compared with lansoprazole: P = 0.038 by log-rank test). No differences were seen in the rate of endoscopic healing of reflux esophagitis at 8 weeks between the three treatment regimens.

Conclusion:  Rabeprazole may be more effective than omeprazole and lansoprazole for the rapid relief of heartburn symptoms in patients with reflux esophagitis.
