Background: Pantoprazole is a benzimidazole derivative which selectively inhibits the proton pump H + , K + ‐ATPase necessary for the final step in gastric acid secretion. Aim: To investigate the tolerability and the prophylactic effect of pantoprazole 40 mg once daily on relapse in patients whose reflux oesophagitis had been healed. Methods: The safety of pantoprazole 40 mg once daily was assessed in an open 1‐year trial on 222 patients whose reflux oesophagitis had been healed with omeprazole or pantoprazole. Relapse was defined as endoscopically‐confirmed reflux oesophagitis (at least Grade I), with endoscopies being performed for patients experiencing 3 consecutive days of disease‐specific symptoms. Results: Kaplan–Meier survival analysis at 6 and 12 months gave estimated treatment failure rates of 2% and 6% from confirmed relapses (per‐protocol), and of 9% and 30% for a worst‐case group (all withdrawals counted as failures). The only population shift in laboratory variables was a doubling of the median serum gastrin level over the first 6 months; thereafter it stabilized. Fifty‐four (24%) patients experienced adverse events; 15 of these withdrew. Serious adverse events were reported for 12 patients. Conclusions: Pantoprazole appears to be highly effective and to have a good safety profile for long‐term prophylaxis of reflux oesophagitis.
