Pantoprazole Macleods Pharma Uk (Pantoprazole Sodium Sesquihydrate)

Pantoprazole acts on the gastric proton pump to lower acid production in several acid‑related disorders.

• Gastro‑esophageal reflux disease (GERD): relieves heartburn and regurgitation by decreasing esophageal acid exposure.
• Erosive esophagitis: promotes healing of acid‑induced esophageal lesions.
• Zollinger‑Ellison syndrome: controls excessive gastric acid secretion caused by gastrin‑producing tumors.
• NSAID‑induced gastric ulcer: aids ulcer healing and prevents recurrence.
• Helicobacter pylori eradication (as part of combination therapy): enhances the effectiveness of antibiotic regimens.

• 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 secretion and thereby lowering gastric acidity.

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

Common Side Effects

• Headache: mild to moderate pain often resolving without intervention.
• Diarrhea: loose stools that may be self‑limiting.
• Nausea: feeling of stomach upset, sometimes with vomiting.
• Abdominal pain: discomfort or cramping in the stomach area.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis): difficulty breathing, swelling, rash.
• Clostridioides difficile infection: persistent watery diarrhea, abdominal pain.
• Low magnesium (hypomagnesemia): muscle cramps, irregular heartbeat.
• Elevated liver enzymes: signs of liver irritation, may require monitoring.
• Stevens‑Johnson syndrome: severe skin rash and mucosal involvement.

Before initiating therapy, consider the following safety measures.

• Assess renal function: dose may need adjustment in severe renal impairment.
• Monitor magnesium levels: prolonged use can lead to hypomagnesemia.
• Avoid abrupt discontinuation: may cause rebound acid hypersecretion.
• Use with caution in hepatic impairment: monitor liver function tests.
• Store at room temperature: keep in the original pack, protect from moisture and light.

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

Major Interactions (Avoid)

• Ketoconazole: reduced absorption and efficacy of ketoconazole.
• Atazanavir: decreased plasma concentrations of atazanavir.
• Clopidogrel: diminished activation of clopidogrel, reducing antiplatelet effect.

Moderate Interactions (Monitor Closely)

• Warfarin: possible increase in INR, requiring closer coagulation monitoring.
• Digoxin: may raise serum digoxin levels, necessitating dose adjustment.
• Methotrexate: risk of increased toxicity, especially at high doses.
