Medical Information

Indications

Pantoprazole is indicated where suppression of acid secretion has therapeutic benefit; i.e

Peptic ulcer diseases
Gastroesophageal reflux diseases
Ulcer induced by non-steroidal anti-inflammatory drugs (NSAIDs)
Eradication of Helicobacter pylori (in combination with antibiotics)
Zollinger-Ellison Syndrome

Pharmacology

Pantoprazole is a proton pump inhibitor that suppresses the final step in gastric acid production by covalently binding to the H+/K+ATPase enzyme system at the surface of the gastric parietal cell. This effect leads to inhibition of both basal and stimulated gastric acid secretion, irrespective of the stimulus that persists longer than 24 hours.

Pregnancy & Lactation

US FDA Pregnancy Category of Pantoprazole is B. There are, however, no adequate and well-controlled studies in pregnant woman. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Pantoprazole has been shown to be excreted in human milk. So, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the benefit of the drug to the mother.

Precautions & Warnings

Patients should be cautioned that Pantoprazole tablet should not be split, chewed or crushed. Long-term therapy of Pantoprazole may lead to malabsorption of cyanocobalamin (Vitamin B12) or may increase the risk of osteoporosis related disorders.

Overdose Effects

There are no known symptoms of overdosage in humans. Since Pantoprazole is highly protein bound, it is not readily dialyzable. Apart from symptomatic and supportive management, no specific therapy is recommended.
