BACKGROUND: It has been demonstrated that therapy with proton pump inhibitors reduces recurrence of bleeding following initial endoscopic treatment of bleeding peptic ulcers. AIM: This study compared the effects of esomeprazole 40 mg and pantoprazole 40 mg on intragastric acid control. Both substances were administered intravenously as 15-min infusion and as bolus injection. METHODS: Healthy men and women volunteers were enrolled in this single-center, open, randomized, three-way crossover study. After administration of esomeprazole 40 mg and pantoprazole 40 mg intravenously as 15-min infusion, and pantoprazole 40 mg intravenously as bolus injection, continuous 24-h intragastric pH monitoring was carried out. RESULTS: pH data were available for 21 Helicobacter pylori-negative and seven H. pylori-positive volunteers. In H. pylori-negative volunteers, esomeprazole 40 mg intravenously resulted in 11.8 h with an intragastric pH>4 compared with 5.6 h for pantoprazole 40 mg intravenously as infusion (P<0.0001), and 7.2 h for pantoprazole 40 mg intravenously as bolus injection (P<0.001). During the first 6 h of administration, the corresponding values were 3.4, 1.1 (P<0.000001), and 2.1 h (P<0.001), respectively. CONCLUSIONS: In H. pylori-negative patients, a single dose of esomeprazole 40 mg intravenously provides an intragastric acid control that is faster and more pronounced than administration of pantoprazole 40 mg intravenously.
