# Sompraz hp (Pantoprazole) ## Overview Pantoprazole is a proton pump inhibitor (PPI) that reduces the amount of acid produced in the stomach. ## Primary Indications * Healing of erosive esophagitis associated with gastroesophageal reflux disease (GERD). * Maintenance of healing of erosive esophagitis. * Treatment of pathological hypersecretory conditions, such as Zollinger-Ellison syndrome. ## Adult Dosing * **Healing of Erosive Esophagitis:** 40 mg orally or intravenously once daily for up to 8 weeks. * **Maintenance of Healing of Erosive Esophagitis:** 40 mg orally once daily. A lower dose of 20 mg orally may be used for maintenance in some patients. * **Pathological Hypersecretory Conditions:** Starting dose is typically 40 mg orally or intravenously twice daily. Doses may be increased as needed. The maximum recommended dose is 240 mg per day intravenously or 400 mg per day orally. ## Pediatric Dosing Dosing for pediatric patients varies by age and indication. Consult specific pediatric guidelines or product labeling. * For children 5 years of age and older for the treatment of GERD and erosive esophagitis: * 20 mg orally once daily for up to 8 weeks for healing. * 10 mg or 20 mg orally once daily for maintenance. ## Dose Adjustments No dose adjustment is typically necessary for patients with hepatic or renal impairment, though caution is advised. ## Contraindications * Known hypersensitivity to pantoprazole, any component of the formulation, or other benzimidazoles. ## Adverse Effects Common adverse effects include headache, diarrhea, nausea, abdominal pain, and dizziness. Long-term use may be associated with an increased risk of Clostridium difficile-associated diarrhea, bone fractures, hypomagnesemia, and vitamin B12 deficiency. ## Key Drug Interactions * **Clopidogrel:** Pantoprazole may decrease the effectiveness of clopidogrel. Consider alternatives if possible or monitor for thrombotic events. * **Drugs dependent on gastric pH for absorption:** PPIs can alter gastric pH, affecting the absorption of drugs like ketoconazole, itraconazole, and certain HIV protease inhibitors. * **Methotrexate:** PPIs may increase methotrexate levels. ## Monitoring * Monitor for signs and symptoms of Clostridium difficile infection. * Monitor serum magnesium levels, especially in patients on long-term therapy (typically for 1 year or more). * Consider monitoring vitamin B12 levels in patients with long-term PPI use. * Monitor for bone fracture risk in patients at risk. ## Clinical Pearls * Pantoprazole is generally taken 30-60 minutes before a meal. * For IV administration, reconstitute and further dilute as per manufacturer instructions. * Be aware of the potential for rebound acid hypersecretion upon discontinuation. Gradual tapering may be considered. *** *This information is intended for clinical use and does not replace comprehensive drug information resources.
