Pantoprazole is a proton pump inhibitor used to treat erosive esophagitis, gastric acid hypersecretion, and to promote healing of tissue damage caused by gastric acid.
Hydrochloric acid (HCl) secretion into the gastric lumen is a process regulated mainly by the H(+)/K(+)-ATPase of the proton pump, expressed in high quantities by the parietal cells of the stomach. ATPase is an enzyme on the parietal cell membrane that facilitates hydrogen and potassium exchange through the cell, which normally results in the extrusion of potassium and formation of HCl (gastric acid). Proton pump inhibitors such as pantoprazole are substituted benzimidazole derivatives, weak bases, which accumulate in the acidic space of the parietal cell before being converted in the canaliculi (small canal) of the gastric parietal cell, an acidic environment, to active sulfenamide derivatives. This active form then makes disulfide bonds with important cysteines on the gastric acid pump, inhibiting its function. Specifically, pantoprazole binds to the sulfhydryl group of H+, K+-ATPase, which is an enzyme implicated in accelerating the final step in the acid secretion pathway. The enzyme is inactivated, inhibiting gastric acid secretion. The inhibition of gastric acid secretion is stronger with proton pump inhibitors such as pantoprazole and lasts longer than with the H(2) antagonists.
Pantoprazole Injection: Treatment of gastroesophageal reflux disease associated with a history of erosive esophagitis Pantoprazole for injection is indicated for short-term treatment (7-10 days) of patients having gastroesophageal reflux disease (GERD) with a history of erosive esophagitis, as an alternative to oral medication in patients who are unable to continue taking pantoprazole delayed-release tablets. Safety and efficacy of pantoprazole injection as the initial treatment of patients having GERD with a history of erosive esophagitis have not been demonstrated at this time. Pathological Hypersecretion Associated with Zollinger-Ellison Syndrome Pantoprazole for injection is indicated for the treatment of pathological hypersecretory conditions associated with Zollinger-Ellison Syndrome or other neoplastic conditions. Pantoprazole delayed-release oral suspension: Short-Term Treatment of erosive esophagitis associated with gastroesophageal reflux disease (GERD) Indicated in adults and pediatric patients five years of age and above for the short-term treatment (up to 8 weeks) in the healing and symptomatic relief of erosive esophagitis. For adult patients who have not healed after 8 weeks of treatment, an additional 8-week course of pantoprazole may be considered. Safety of treatment beyond 8 weeks in pediatric patients has not been determined. Maintenance of healing of erosive esophagitis Indicated for maintenance of healing of erosive esophagitis and reduction in relapse rates of daytime and nighttime heartburn symptoms in adult patients with GERD. Pathological hypersecretory conditions including Zollinger-Ellison syndrome Indicated for the long-term treatment of the above conditions.
