## Sompraz
**Overview:** Sompraz (generic name: pantoprazole) is a proton pump inhibitor (PPI) used to reduce stomach acid production.
**Primary Indications:**
* Gastroesophageal reflux disease (GERD)
* Erosive esophagitis
* Zollinger-Ellison syndrome
* Healing of duodenal ulcers
* H. pylori eradication (in combination therapy)
**Adult Dosing:**
* **GERD/Erosive Esophagitis:** 40 mg orally once daily. Duration of treatment varies.
* **Healing of Duodenal Ulcers:** 40 mg orally once daily, typically for 7 days.
* **Zollinger-Ellison Syndrome:** Starting dose is typically 40 mg orally twice daily. Dosage should be individualized based on gastric acid output. The maximum recommended dose is 80 mg every 12 hours or 160 mg once daily.
* **H. pylori Eradication (Triple Therapy):** 40 mg orally twice daily for 7-14 days in combination with antibiotics (e.g., amoxicillin and clarithromycin).
**Pediatric Dosing:**
* **GERD/Erosive Esophagitis (ages 5 to 16 years):** 20 mg to 40 mg orally once daily. The dose should be individualized.
**Dose Adjustments:**
* **Hepatic Impairment:** For patients with severe hepatic impairment, consider a dose reduction to 20 mg once daily.
**Contraindications:**
* Hypersensitivity to pantoprazole or any component of the formulation.
**Adverse Effects:**
* **Common:** Headache, diarrhea, nausea, abdominal pain, dizziness, flatulence.
* **Serious (less common):** Clostridium difficile-associated diarrhea, bone fractures (hip, wrist, spine) with long-term use, vitamin B12 deficiency, hypomagnesemia (can be serious, especially with prolonged use), potential for increased risk of gastric polyps (fundic gland polyps).
**Key Drug Interactions:**
* **Drugs requiring gastric acid for absorption:** Ketoconazole, itraconazole, iron salts, and some antiretrovirals (e.g., nelfinavir). Pantoprazole can decrease absorption.
* **Warfarin:** May increase INR and prothrombin time. Monitor INR closely.
* **Methotrexate:** PPIs may increase methotrexate levels, potentially leading to toxicity.
**Monitoring:**
* Electrolytes (especially magnesium) with long-term therapy.
* Bone mineral density with long-term therapy.
* Monitor for signs and symptoms of C. difficile infection.
**Clinical Pearls:**
* Administer 30 minutes before a meal.
* Pantoprazole delayed-release tablets should be swallowed whole and not chewed or crushed.
* Long-term use of PPIs is associated with potential risks and should be re-evaluated regularly.
