Generic Name

Pantoprazole Sodium Sesquihydrate

Precaution

Gastric malignancy should be ruled out. Consider Zn++ supplementation during IV therapy in patients who are prone to Zn++ deficiency. Pregnancy. Monitoring Parameters Monitor Mg levels prior to initiation and periodically during prolonged use. Lactation Risk Summary Pantoprazole has been detected in breast milk of a nursing mother after a single 40 mg oral dose of pantoprazole. There were no effects on the breastfed infant. There are no data on pantoprazole effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for PROTONIX and any potential adverse effects on the breastfed child from pantoprazole or from the underlying maternal condition.

Mode of Action

Pantoprazole is a substituted benzimidazole, and also known as PPI due to its property to block the final step of acid secretion by inhibiting H+/K+ ATPase enzyme system in gastric parietal cell. Both basal and stimulated acid are inhibited.

Interaction

Increased risk of digoxin-induced cardiotoxic effects. Increased risk of hypomagnesaemia w/ diuretics. May increase INR and prothrombin time of warfarin. May increase serum concentration of methotrexate and saquinavir. Delayed absorption and decreased bioavailability w/ sucralfate. Decreased absorption of ketoconazole, itraconazole. Potentially Fatal: May decrease serum levels and pharmacological effects of rilpivirine, atazanavir and nelfinavir.

Pregnancy Category Note

Pregnancy There are no adequate and well-controlled studies in pregnant women; advise pregnant women of the potential risk of fetal harm; drug should be used during pregnancy only if potential benefit justifies potential risk to fetus Lactation Pantoprazole and metabolites are excreted in milk of rats. Pantoprazole excretion in human milk has been detected in a study of a single nursing mother after a single 40 mg oral dose of pantoprazole sodium; clinical relevance of this finding not known; many drugs excreted in human milk have potential for serious adverse reactions in nursing infants; based on potential for tumorigenicity shown for pantoprazole sodium in rodent carcinogenicity studies, a decision should be made whether to discontinue nursing or to discontinue drug, taking into account benefit of drug to mother
