Pantoprazolo Eg (Pantoprazole Sodium Sesquihydrate)

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

• Gastro‑oesophageal reflux disease (GERD): provides symptomatic relief and promotes healing of the oesophageal lining.
• Erosive oesophagitis: heals erosions and reduces further damage.
• Peptic ulcer disease: supports ulcer healing and prevents recurrence.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion.
• Helicobacter pylori eradication regimens (as adjunct): enhances eradication success when combined with antibiotics.

• Pantoprazole selectively and irreversibly binds to the H+/K+‑ATPase enzyme (the gastric proton pump) on the secretory surface of parietal cells. By inhibiting this final step of acid production, it markedly lowers gastric acidity, allowing mucosal healing and symptom control in acid‑related disorders.

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

Common Side Effects

• Headache: mild to moderate intensity.
• Diarrhoea: usually transient.
• Nausea or abdominal discomfort: occasional.
• Flatulence: mild bloating.
• Constipation: infrequent.
• Dry mouth: occasional.

Serious or Rare Side Effects

• Acute interstitial nephritis: signs of renal impairment.
• Severe hypersensitivity reactions: rash, angio‑edema, anaphylaxis.
• Clostridioides difficile infection: persistent diarrhoea.
• Osteoporotic fractures: with long‑term high‑dose use.
• Vitamin B12 deficiency: prolonged therapy may reduce absorption.

When prescribing Pantoprazolo Eg, clinicians should consider several safety aspects.

• Assess renal function: dose adjustment may be required in severe impairment.
• Review concomitant medications: potential for altered absorption of drugs that need an acidic environment.
• Monitor long‑term users: watch for bone density loss and magnesium levels.
• Use caution in pregnancy: only if clearly needed after risk‑benefit evaluation.
• Avoid in known hypersensitivity: discontinue if allergic reactions develop.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture.

Pantoprazolo Eg may affect the pharmacokinetics of several co‑administered drugs.

Major Interactions (Avoid)

• Ketoconazole or itraconazole: reduced antifungal absorption; avoid concurrent use.
• Atazanavir: markedly decreased antiviral exposure; contraindicated.

Moderate Interactions (Monitor Closely)

• Warfarin: possible increase in INR; monitor coagulation parameters.
• Digoxin: slight increase in serum levels; check therapeutic range.
• Methotrexate (high dose): reduced clearance; monitor for toxicity.
• Clopidogrel: diminished antiplatelet effect; consider alternative therapy.
