Pantoprazole Apharma (Pantoprazole)

Pantoprazole is indicated for several acid‑related gastrointestinal conditions, acting on the gastric proton pump to lower acid output.

• Gastro‑oesophageal reflux disease (GERD): alleviates heartburn and promotes healing of the oesophageal lining.
• Erosive oesophagitis: facilitates mucosal repair and symptom relief.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion.
• NSAID‑induced gastric ulcer: aids ulcer healing and prevents recurrence.
• Helicobacter pylori eradication (as part of combination therapy): enhances eradication rates by suppressing acid.

• Pantoprazole selectively and irreversibly binds to the H+/K+‑ATPase enzyme (the gastric proton pump) on the secretory surface of parietal cells, inhibiting the final step of acid production. This results in a sustained reduction of gastric acidity, allowing damaged mucosa to heal and decreasing reflux‑related symptoms.

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

Common Side Effects

• Headache: mild to moderate intensity.
• Diarrhoea: watery stools, usually transient.
• Nausea: occasional upset stomach.
• Abdominal pain: cramping or discomfort.
• Flatulence: increased gas.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Clostridioides difficile infection: persistent diarrhoea.
• Low serum magnesium: muscle cramps or irregular heartbeat.
• Vitamin B12 deficiency: fatigue or neuropathy with long‑term use.
• Hepatic enzyme elevation: abnormal liver function tests.
• Acute pancreatitis: sudden abdominal pain with nausea.

Before initiating therapy, consider the following precautions:

• Renal function assessment: adjust use in severe impairment.
• Magnesium monitoring: check levels during prolonged treatment.
• Liver disease evaluation: use cautiously in hepatic impairment.
• Elderly patients: start at the lowest effective dose.
• Discontinuation: taper if long‑term use to avoid rebound acid hypersecretion.
• Store at ambient temperature: keep below 25 °C, in the original container, protected from moisture.

Pantoprazole may interact with several medicines, affecting their absorption or metabolism.

Major Interactions (Avoid)

• Ketoconazole: reduced antifungal absorption; avoid concurrent use.
• Atazanavir: decreased antiviral efficacy; avoid co‑administration.
• Clarithromycin: increased risk of cardiac arrhythmia; avoid together.

Moderate Interactions (Monitor Closely)

• Warfarin: possible alteration of anticoagulant effect; monitor INR.
• Methotrexate: increased serum levels; check renal function.
• Digoxin: reduced absorption; assess serum concentrations.
