Ipraalox (Pantoprazole)

Pantoprazole acts on the gastric acid secretion pathway and is indicated for several acid‑related disorders.

• Gastro‑oesophageal reflux disease (GERD): alleviates heartburn and promotes healing of the oesophageal lining.
• Erosive oesophagitis: facilitates mucosal repair and reduces further acid injury.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion associated with gastrin‑producing tumours.
• Peptic ulcer disease: supports ulcer healing by maintaining a low‑acid environment.
• Helicobacter pylori eradication regimens (as adjunct): enhances the effectiveness of antibiotic‑based therapy.

• Pantoprazole selectively and irreversibly inhibits the H+/K+‑ATPase enzyme (the gastric proton pump) located on the secretory surface of parietal cells. By blocking this final step of acid secretion, it markedly lowers gastric acidity, allowing the gastrointestinal mucosa to heal and reducing reflux‑related symptoms.

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

Common Side Effects

• Headache: mild to moderate intensity.
• Diarrhoea: loose stools, often transient.
• Nausea: occasional feeling of queasiness.
• Abdominal pain: mild discomfort in the stomach area.
• Flatulence: increased intestinal gas.
• Constipation: reduced bowel movements.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis): rash, swelling, breathing difficulty.
• Clostridioides difficile infection: persistent diarrhoea, abdominal cramping.
• Low magnesium levels (hypomagnesemia): muscle cramps, irregular heartbeat.
• Liver enzyme elevation: signs of hepatic stress.
• Bone fractures (with long‑term use): increased risk of hip, wrist or spine fractures.

When using Pantoprazole, consider the following precautions:

• Assess renal function: dose adjustment may be needed in severe impairment.
• Monitor magnesium levels: prolonged therapy can lead to hypomagnesemia.
• Evaluate for H. pylori infection: may require combination therapy.
• Use cautiously in patients with liver disease: monitor hepatic function.
• Avoid abrupt discontinuation: may cause rebound acid hypersecretion.
• Store at ambient temperature: keep in the original packaging, protect from moisture and heat.

Pantoprazole can interact with several medicines, requiring attention to dosing and monitoring.

Major Interactions (Avoid)

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

Moderate Interactions (Monitor Closely)

• Warfarin: potential alteration of INR values.
• Methotrexate: increased serum levels, especially at high doses.
• Digoxin: possible increase in serum concentration.
• Oral contraceptives: reduced efficacy may occur.
