Pantoprazole is a proton pump inhibitor that inhibits gastric acid secretion and used for short-term treatment of erosive esophagitis associated with gastroesophageal reflux disease. Pantoprazole suppresses the final step in gastric acid production by covalently binding to the (H+, K+)-ATPase enzyme system at the secretory surface of the gastric parietal cell. This effect leads to inhibition of both basal and stimulated gastric acid secretion, irrespective of the stimulus. The binding to the (H+, K+)-ATPase results in a duration of antisecretory effect that persists longer than 24 hours. Pantoprazole is used for short-term treatment of erosion and ulceration of the esophagus for adults and pediatric patients 5 years of age and older caused by gastroesophageal reflux disease. It can be used as a maintenance therapy for long-term use after initial response is obtained, but there have not been any controlled studies about the use of pantoprazole past a duration of 12 months. Pantoprazole may also be used in combination with antibiotics to treat ulcers caused by Helicobacter pylori. Use of pantoprazole may increase the chance of developing infections such as pneumonia, particularly in hospitalized patients.

Sample Use Guides

Oral use: Short-Term Treatment of Erosive Esophagitis Associated With GERD: 40 mg Once daily for up to 8 weeks; Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome: 40 mg Twice daily IV: The recommended adult dose is 40 mg pantoprazole given once daily by intravenous infusion for 7 to 10 days
Route of Administration: Other
To determine "ex vivo" gastric mucosa gastric acid secretion, pantoprazole (as DMSO solution diluted with serosal fluid) was added to membrane mucosa liquid in the bath tube. Pantoprazole final concentration in serosal fluidwas 5 mkM, incubation time -- 2.5h. Pantoprazole mediated gastric acid secretion inhibition is 24.3% at 5mkM.
