# Sompraz HP (Generic name: Pantoprazole)
## Overview
Pantoprazole is a proton pump inhibitor (PPI) that decreases the amount of acid produced in the stomach.
## Primary Indications
* Gastroesophageal reflux disease (GERD)
* Healing of erosive esophagitis
* Dose reduction of gastric acid secretion in pathological hypersecretory conditions (e.g., Zollinger-Ellison syndrome)
* H. pylori eradication (in combination with antibiotics)
## Adult Dosing
* **GERD/Healing erosive esophagitis:** 40 mg once daily.
* **Pathological hypersecretory conditions:** Starting dose is typically 40 mg twice daily, may be increased as clinically needed. Usual range 40-80 mg daily. Maximum dose 80 mg twice daily.
* **H. pylori eradication:** 40 mg twice daily with amoxicillin and clarithromycin, or with clarithromycin and metronidazole.
## Pediatric Dosing
* **GERD/Healing erosive esophagitis:**
* **12 years and older:** 40 mg once daily.
* **Less than 12 years:** Dosing is based on body weight, typically 20-40 mg once daily. Consult specific pediatric guidelines for precise dosing by weight.
## Dose Adjustments
* **Hepatic impairment:** Maximum dose of 40 mg once daily.
* **Renal impairment:** No dose adjustment necessary.
## Contraindications
* Known hypersensitivity to pantoprazole or any component of the formulation.
## Adverse Effects
Common: Headache, diarrhea, nausea, abdominal pain, dizziness, flatulence.
Serious:
* Long-term use associated with **increased risk of fractures** (hip, wrist, spine), **Clostridioides difficile-associated diarrhea**, **low magnesium levels** (hypomagnesemia), and **vitamin B12 deficiency**.
* Acute interstitial nephritis.
## Key Drug Interactions
* **Drugs dependent on gastric pH for absorption:** Ketoconazole, itraconazole, posaconazole, iron salts, and some antiretrovirals (e.g., rilpivirine, atazanavir) may have decreased absorption.
* **Methotrexate:** May increase methotrexate levels.
* **CYP2C19 substrates:** May increase levels of drugs metabolized by CYP2C19 (e.g., clopidogrel).
## Monitoring
* Monitor for signs and symptoms of hypomagnesemia (e.g., muscle cramps, seizures, tremor, arrhythmias) with prolonged use.
* Monitor for signs of C. difficile infection.
* Consider monitoring vitamin B12 levels with long-term therapy.
## Clinical Pearls
* Administer 30 minutes to 1 hour before a meal.
* Pantoprazole delayed-release tablets should be swallowed whole and not chewed or crushed.
* Long-term use should be reserved for patients with a clear indication, and the lowest effective dose should be used.
* PPIs are not indicated for occasional heartburn or dyspepsia.
