Pantoprazole Teva Italia (Pantoprazole Sodium)

Pantoprazole is a proton pump inhibitor that acts on the acid‑secretion pathway of the stomach.

• Gastro‑oesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of the oesophageal lining.
• Erosive oesophagitis: accelerates mucosal healing and reduces recurrence.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion associated with the disorder.

• Pantoprazole sodium inhibits the H+/K+‑ATPase enzyme (the gastric proton pump) located on the secretory surface of parietal cells. By binding covalently to the pump’s cysteine residues, it blocks the final step of acid production, leading to a sustained reduction in gastric acidity and an elevated gastric pH.

Pantoprazole is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Headache: mild to moderate intensity.
• Diarrhoea: usually self‑limiting.
• Nausea: occasional and transient.
• Abdominal pain: mild discomfort.
• Flatulence: increased intestinal gas.
• Constipation: occasional bowel habit change.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis): difficulty breathing, swelling of face or throat.
• Clostridioides difficile infection: persistent watery diarrhoea.
• Low magnesium levels (hypomagnesemia): muscle cramps, irregular heartbeat.
• Bone fractures: increased risk with long‑term use.
• Liver enzyme elevation: signs of hepatitis.
• Acute interstitial nephritis: kidney inflammation.

When prescribing Pantoprazole, clinicians should consider several safety aspects.

• Renal impairment: adjust monitoring if kidney function is reduced.
• Hepatic impairment: use with caution in patients with liver disease.
• Long‑term therapy: evaluate need periodically to avoid unnecessary exposure.
• Concomitant use of bisphosphonates or iron supplements: separate dosing times to improve absorption.
• Pregnancy and lactation: prescribe only if benefit outweighs potential risk.
• Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Pantoprazole may affect the plasma concentrations of several co‑administered medicines.

Major Interactions (Avoid)

• Ketoconazole or itraconazole: reduced antifungal absorption due to higher gastric pH.
• Atazanavir: markedly decreased antiviral exposure, risking treatment failure.

Moderate Interactions (Monitor Closely)

• Clopidogrel: diminished antiplatelet effect, may require alternative therapy.
• Warfarin: potential increase in INR, necessitating closer coagulation monitoring.
• Methotrexate: higher systemic levels, especially with high‑dose regimens.
• Digoxin: modest rise in serum concentration, monitor for toxicity.
