Background/Aims: The effects of Histamine-2 receptor antagonists and proton pump inhibitors on the gastrointestinal motility have not yet been sufficiently investigated. The aim of this study was to determine the effects of intravenous bolus administration of famotidine and omeprazole on the rate of gastric emptying using the continuous 13C breath test (BreathID system, Exalenz Bioscience Ltd, Israel).
Methods: Twelve healthy male volunteers participated in this randomized, 3-way crossover study. After fasting overnight, the subjects were randomly assigned to receive 20 mg of famotidine, 20 mg of omeprazole or 20 mL of saline alone by intravenous bolus injection before a test meal (200 kcal per 200 mL, containing 100 mg of 13C-acetate). Gastric emptying was monitored for 4 hours after the ingestion of test meal by the 13C-acetic acid breath test performed using the BreathID system.
Results: No significant differences in the calculated parameters, namely, the T1/2, Tlag, GEC, b and k, were observed among the 3 test conditions.
Conclusions: The study revealed that intravenous administration of gastric acid suppressant drugs had no significant influence on the rate of gastric emptying in comparison with that of saline alone as a placebo. Our results indicating the absence of any effect of either famotidine or omeprazole on accelerating the rate of gastric emptying suggest that both medications can be administered safely to patients suffering from hemorrhagic peptic ulcers who need to be kept nil by mouth from the viewpoint of possible acceleration of gastrointestinal motility in the clinical setting.
