BACKGROUND: Omeprazole, a H+/K+ ATPase inhibitor, has been shown to reduce gastric bicarbonate secretion in cats. However, there has been no study on the effect of omeprazole on bicarbonate secretion in patients with duodenal ulcer (DU).
METHODS: Fifteen men with duodenal ulcer (mean age 38 years, range 22-57) were included. Baseline gastric acid output, bicarbonate secretion, and parietal and nonparietal secretions were estimated before and after omeprazole therapy (20 mg/day) for four weeks.
RESULTS: Omeprazole administration did not significantly alter bicarbonate secretion (3.3 [1.2] vs 2.4 [0.4] mmol/h), though there was significant reduction in gastric acidity (44.2 [6.6] vs 20.7 [4.6] mmol/L, p < 0.01).
CONCLUSION: Omeprazole reduces acid secretion but does not affect gastric bicarbonate secretion in patients with DU.
