Preparing Pantoprazole (Pantop) Infusion at 8mg/hr
For standard upper GI bleeding management, prepare pantoprazole as an 80mg IV bolus followed by continuous infusion at 8mg/hr for 72 hours after endoscopic hemostasis. 1
Standard Preparation Protocol
Initial Bolus Dose
- Administer 80mg pantoprazole IV bolus over 15 minutes before starting the continuous infusion 1
- This loading dose is critical to rapidly achieve therapeutic gastric pH levels above 6, which is necessary for platelet aggregation and clot stability 1
Continuous Infusion Setup
- Concentration: Mix 240mg pantoprazole in 240mL of normal saline or 5% dextrose (creates 1mg/mL solution) 2
- Infusion rate: Set pump to deliver 8mL/hr to achieve 8mg/hr 1
- Duration: Continue for exactly 72 hours after successful endoscopic therapy 1
Alternative Preparation Method
- Some institutions use 160mg in 200mL (0.8mg/mL concentration) and run at 10mL/hr to achieve 8mg/hr 2
- Both methods are acceptable; choose based on your institution's protocol
Administration Guidelines
Infusion Considerations
- Administer slowly over at least 15 minutes to minimize risk of thrombophlebitis at the infusion site 1
- Use dedicated IV line when possible to avoid incompatibilities 1
- Peripheral access is acceptable, but central line preferred for prolonged infusions to reduce phlebitis risk 1
Monitoring During Infusion
- Check infusion site regularly for signs of thrombophlebitis (pain, redness, swelling) 1
- If thrombophlebitis develops, apply warm compresses and consider switching to central access 1
- Monitor for adequate acid suppression by clinical response (no rebleeding) 1
Post-Infusion Transition
After 72-Hour Infusion Period
- Transition to oral pantoprazole 40mg twice daily on days 4-14 1
- Then reduce to 40mg once daily from day 15 onward for 6-8 weeks total to allow complete mucosal healing 1
- Do not discontinue PPI therapy prematurely, as this increases rebleeding risk 1
Critical Caveats
Patient Selection
- This high-dose regimen is specifically for nonvariceal upper GI bleeding with high-risk stigmata (active bleeding, visible vessel, or adherent clot) after successful endoscopic hemostasis 1
- Benefits are most pronounced in this high-risk population 1
Common Pitfalls to Avoid
- Never delay endoscopy while relying solely on PPI therapy—PPIs are adjunctive to endoscopic hemostasis, not a replacement 1
- Infusing too rapidly increases thrombophlebitis risk; maintain 15-minute minimum administration time for bolus 1
- Stopping infusion before 72 hours or discontinuing oral therapy before 6-8 weeks may not allow adequate mucosal healing 1
Special Populations
- No dosage adjustment needed for elderly patients or those with renal impairment 3, 4
- For patients with severe hepatic cirrhosis (Child-Pugh B or C), standard dosing is still appropriate for short-term use, though metabolism may be slower 5, 4
Drug Interactions
- Pantoprazole has minimal cytochrome P450 interactions, simplifying use in critically ill patients on multiple medications 5, 4
- Concomitant antacids do not affect pantoprazole efficacy 5
Equivalent Alternative
Omeprazole can be substituted using identical dosing: 80mg IV bolus followed by 8mg/hr continuous infusion for 72 hours, as both achieve comparable outcomes when dosed appropriately 1
