Pantoprazole Reig Jofre Uk (Pantoprazole)

Pantoprazole is a proton pump inhibitor that acts on the gastric acid secretion pathway. It is indicated for several acid‑related conditions:

• Gastro‑oesophageal reflux disease (GERD): alleviates heartburn and promotes healing of the oesophageal lining.
• Erosive oesophagitis: heals erosions caused by chronic acid exposure.
• Peptic ulcer disease: supports ulcer healing and reduces recurrence risk.
• Zollinger‑Ellison syndrome: controls excessive gastric acid production.
• Helicobacter pylori eradication regimens: used as part of combination therapy to improve eradication rates.

• Pantoprazole selectively 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 secretion, leading to prolonged elevation of gastric pH and reduced acidity in the stomach.

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: excess gas.
• Constipation: infrequent.

Serious or Rare Side Effects

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

When prescribing Pantoprazole, clinicians should consider several safety aspects:

• Assess renal function: adjust use in severe impairment.
• Review concomitant medications: potential for altered drug levels.
• Evaluate bone health: long‑term therapy may affect calcium absorption.
• Monitor electrolytes: especially magnesium during prolonged treatment.
• Use cautiously in pregnancy: weigh benefits against potential risks.

Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Pantoprazole may affect the pharmacokinetics of several co‑administered drugs.

Major Interactions (Avoid)

• Antifungal agents (e.g., itraconazole, ketoconazole): reduced absorption due to higher gastric pH.
• HIV protease inhibitors (e.g., atazanavir): decreased plasma concentrations.

Moderate Interactions (Monitor Closely)

• Warfarin: possible increase in INR, monitor coagulation.
• Methotrexate: reduced clearance, watch for toxicity.
• Digoxin: slight increase in serum levels, observe for signs of toxicity.
• Clopidogrel: potential reduction in antiplatelet effect, consider alternative therapy.
