Pantoprazole 💊
📖 About
Always check the BNF link here for the most up-to-date guidance. Pantoprazole is a proton pump inhibitor (PPI) used in the management of peptic ulcer disease, gastro-oesophageal reflux, oesophagitis, and in acute upper GI bleeding.
⚙️ Mode of Action
- 🔒 Irreversibly inhibits the gastric H⁺/K⁺ ATPase (proton pump) in parietal cells.
- ⬇️ Suppresses both basal and stimulated gastric acid secretion.
- Provides prolonged acid suppression compared to H₂ receptor antagonists.
💊 Indications / Dose
- Upper GI bleed 🩸: 80 mg IV over 1 hour, then 8 mg/hour IV infusion for 72 hours in glucose 5% or 0.9% NaCl → reduces rebleeding rate.
- Peptic ulcer disease / GORD / oesophagitis 🫀:
- Oral: 20–40 mg once daily (max 80 mg/day).
- IV: 40 mg slow IV once daily (if oral route not possible).
- NSAID-associated ulcer prophylaxis 💊: 20–40 mg once daily.
🔗 Interactions
- ⚠️ PPIs may reduce the effectiveness of clopidogrel (due to CYP2C19 inhibition).
- May increase serum levels of drugs dependent on gastric pH for absorption (e.g., ketoconazole, atazanavir).
⚠️ Cautions
- 🩺 Use with care in liver disease (dose adjustment may be required).
- 🦴 Long-term use: risk of osteoporosis-related fractures, hypomagnesaemia, and vitamin B12 deficiency.
- 🦠 May increase risk of GI infections (e.g., C. difficile).
⛔ Contraindications
- 🚫 Hypersensitivity to pantoprazole or other PPIs.
- 📖 See BNF for full details.
😬 Side Effects
- 🤢 GI: Abdominal pain, constipation, diarrhoea, nausea, vomiting.
- 🤕 CNS: Headache, dizziness.
- 🦠 Infections: Risk of pneumonia and C. difficile diarrhoea with prolonged use.
- 🦴 Long-term: Bone fractures, hypomagnesaemia, vitamin B12 deficiency.
