Pantoprazole Laboratorio Reig Jofre (Pantoprazole)

Pantoprazole is a proton pump inhibitor used to manage acid‑related gastrointestinal conditions.

• Gastroesophageal reflux disease (GERD): provides acid suppression to relieve symptoms and promote mucosal healing.
• Erosive esophagitis: reduces gastric acidity to allow damaged esophageal tissue to recover.
• Peptic ulcer disease: diminishes acid secretion to support ulcer healing and prevent recurrence.
• Stress ulcer prophylaxis: offers rapid acid control in critically ill patients at risk of stress‑related gastric lesions.

• 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 production, it markedly reduces basal and stimulated gastric acid secretion, leading to an elevated gastric pH and facilitating healing of acid‑related lesions.

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

Common Side Effects

• Headache: mild to moderate intensity.
• Diarrhea: watery stools without blood.
• Nausea: occasional feeling of queasiness.
• Abdominal pain: mild discomfort in the stomach area.
• Flatulence: increased intestinal gas.

Serious or Rare Side Effects

• Clostridioides difficile infection: severe colitis presenting with watery diarrhea.
• Anaphylaxis: sudden, life‑threatening allergic reaction with rash, swelling, and respiratory distress.
• Hypomagnesemia: low serum magnesium causing muscle cramps or arrhythmias.
• Elevated liver enzymes: potential hepatic injury indicated by increased ALT/AST.
• Stevens‑Johnson syndrome: rare severe skin reaction with blistering and mucosal involvement.

When using Pantoprazole intravenously, consider the following safety measures.

• Assess renal function: adjust therapy in patients with severe renal impairment.
• Monitor electrolytes: watch for hypomagnesemia during prolonged treatment.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Use cautiously in hepatic impairment: dose may need adjustment.
• Pregnancy and lactation: evaluate risk versus benefit before prescribing.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Pantoprazole may interact with several medications; awareness of interaction severity is essential.

Major Interactions (Avoid)

• Clopidogrel: reduced antiplatelet effect, increasing cardiovascular risk.
• Methotrexate: decreased renal clearance leading to toxicity.
• Atazanavir: markedly reduced antiviral absorption.

Moderate Interactions (Monitor Closely)

• Warfarin: possible increase in INR, requiring closer monitoring.
• Digoxin: may raise serum digoxin levels, risking toxicity.
• Fluconazole: can elevate pantoprazole plasma concentrations, necessitating dose review.
