Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Proton pump inhibitor (PPI) that irreversibly inhibits the H+/K+-ATPase enzyme system (proton pump) at the secretory surface of gastric parietal cells, suppressing basal and stimulated gastric acid secretion.
Pantoprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+-ATPase enzyme system at the secretory surface of gastric parietal cells.
15 mg orally once daily for 14 days.
40 mg intravenously once daily for 7-10 days; for pathological hypersecretory conditions, initial dose 80 mg IV every 12 hours, titrate per acid output.
