Pantoprazole versus lansoprazole in French patients with reflux esophagitis.
OBJECTIVE
The aim of this study was to compare the efficacy of pantoprazole 40 mg and lansoprazole 30 mg given for 4 to 8 weeks on endoscopic healing and symptom relief in grade II-III reflux esophagitis patients (according to Savary-Miller classification).


METHODS
Four hundred and sixty one patients were included (pantoprazole n=226, lansoprazole n=235) in this prospective, randomized, multicenter double-blind study. Endoscopic control was performed at 4 weeks and at 8 weeks if esophagitis was not healed.


RESULTS
In the intention-to-treat analysis, the healing rates at 4 weeks were 81 and 80% in the pantoprazole and lansoprazole groups, respectively (NS), 90 and 86% at 8 weeks (NS). In the per-protocol analysis, the healing rates at 4 weeks were 86% in the 2 groups and at 8 weeks 97% in the pantoprazole group and 93% in the lansoprazole group (NS). The heartburn relief rates at day 14 were 88% and 86% in the pantoprazole and lansoprazole groups, respectively. Only esophagitis grade at entry was shown to be a predictive factor for healing at 4 weeks (P<0.0001).


CONCLUSIONS
This study showed that pantoprazole 40 mg once daily is as effective and well tolerated as lansoprazole 30 mg once daily in the treatment of grade II-III acute reflux esophagitis.
