### Pantoprazole **Overview** Pantoprazole is a proton pump inhibitor (PPI) that decreases the amount of acid produced in the stomach. **Primary Indications** * Erosive esophagitis associated with GERD. * Pathological hypersecretory conditions (e.g., Zollinger-Ellison syndrome). * Maintenance of healing of erosive esophagitis. * Treatment of heartburn associated with GERD. **Adult Dosing** * **Erosive esophagitis:** 40 mg orally or intravenously once daily for up to 8 weeks. A subsequent 8-week course may be considered for patients who have not healed. * **Maintenance of healing of erosive esophagitis:** 40 mg orally once daily. * **Symptomatic GERD (heartburn):** 20 mg orally once daily for up to 14 days. * **Pathological hypersecretory conditions:** 40 mg orally or intravenously twice daily, may be increased to a maximum of 80 mg twice daily. **Pediatric Dosing** * **Erosive esophagitis (ages 5-16 years):** 20 mg orally once daily for up to 4 weeks. If not healed, may consider an additional 4 weeks. * **Erosive esophagitis (ages 16-17 years):** 40 mg orally once daily for up to 8 weeks. **Dose Adjustments** * **Hepatic impairment:** Maximum daily dose of 40 mg orally once daily. **Contraindications** * Known hypersensitivity to pantoprazole or any component of the formulation. **Adverse Effects** * Common: Headache, diarrhea, nausea, abdominal pain, dizziness, flatulence. * Long-term use associated with increased risk of fractures (hip, wrist, spine), *Clostridium difficile*-associated diarrhea, vitamin B12 deficiency, and hypomagnesemia. **Key Drug Interactions** * **Clopidogrel:** Pantoprazole may decrease the antiplatelet effect of clopidogrel; consider alternative PPIs or monitor for efficacy if concurrent use is necessary. * **Drugs dependent on gastric pH for absorption:** Absorption of ketoconazole, itraconazole, and other azole antifungals may be reduced. Absorption of certain antiretrovirals may be affected. * **Methotrexate:** PPIs may increase methotrexate levels; consider dose reduction or temporary discontinuation. **Monitoring** * Assess for improvement of GERD symptoms. * Monitor for magnesium levels, especially with prolonged therapy (>1 year) or concurrent diuretic use. * Monitor for signs and symptoms of *Clostridium difficile*-associated diarrhea. **Clinical Pearls** * Administer orally 30-60 minutes before a meal. * Swallow delayed-release capsules or tablets whole; do not crush or chew. * IV administration is an option when oral route is not feasible. *** **Disclaimer:** This information is intended for clinical use and does not replace professional judgment.
