# Sompraz HP (Pantoprazole)
## Overview
Pantoprazole is a proton pump inhibitor (PPI) that reduces gastric acid production.
## Primary Indications
* Healing of erosive esophagitis associated with gastroesophageal reflux disease (GERD).
* Maintenance of healing of erosive esophagitis.
* Treatment of pathological hypersecretory conditions, including Zollinger-Ellison syndrome.
## Adult Dosing
* **Healing of erosive esophagitis:** 40 mg orally once daily for up to 8 weeks.
* **Maintenance of healing of erosive esophagitis:** 40 mg orally once daily.
* **Pathological hypersecretory conditions:** Starting dose is typically 40 mg orally twice daily, but may be increased based on clinical need. Doses up to 240 mg daily have been administered intravenously.
## Pediatric Dosing
Dosing varies significantly by indication and age.
* **GERD (erosive esophagitis):**
* 1 year to 5 years: 10 mg to 20 mg orally once daily.
* 5 years to 16 years: 20 mg to 40 mg orally once daily.
* Dosing for pathological hypersecretory conditions in pediatrics is not well-established and requires careful consideration and specialist consultation.
## Dose Adjustments
No dose adjustment is generally required for hepatic or renal impairment, although caution may be warranted in severe hepatic impairment.
## Contraindications
* Known hypersensitivity to pantoprazole or any component of the formulation.
* Use of rilpivirine-containing products.
## Adverse Effects
Common adverse effects include headache, diarrhea, nausea, abdominal pain, vomiting, dizziness, and rash. Long-term use of PPIs may be associated with increased risk of C. difficile infection, bone fractures (hip, wrist, spine), and vitamin B12 deficiency.
## Key Drug Interactions
* **Clopidogrel:** Pantoprazole may decrease the antiplatelet effect of clopidogrel. Consider alternatives or monitor closely.
* **Methotrexate:** PPIs may increase methotrexate levels, potentially leading to toxicity.
* **Drugs requiring gastric acid for absorption:** Reduced gastric acidity may decrease the absorption of drugs like ketoconazole, itraconazole, and certain HIV medications (e.g., rilpivirine, nelfinavir).
## Monitoring
* Assess for improvement of GERD symptoms.
* Monitor for signs and symptoms of C. difficile infection.
* Consider monitoring vitamin B12 levels and bone mineral density with prolonged therapy.
## Clinical Pearls
* Administer orally administered pantoprazole 30-60 minutes before a meal.
* Do not crush or chew delayed-release tablets; swallow whole.
* IV formulation is available for patients unable to take oral medication.
* Long-term use should be re-evaluated periodically, and the lowest effective dose should be used.
