Conditions

Peptic Ulcer With Haemorrhage

Brief summary

Upper gastrointestinal hemorrhage (UGIH) is common urgency condition.The estimate mortality rate about 7 percent from peptic ulcers disease(PUD). A proton pump inhibitors (PPIs) intravenous infusion are standard treatment for high risk ulcer bleeding. Vonoprazan,subclass of potassium-competitive acid blockers (P-CABs), have beneficial effects including rapid, long-lasting and strong acid suppression.The investigators design a randomized-controlled trial comparison between 72 hours of intravenous PPIs infusion and oral vonoprazan in high risk ulcer UGIH after achieve endoscopic hemostasis. Outcome measurement are re-bleeding rate in 30 days as primary and re-bleeding rate in 3 days, 30 days mortality, rate of angioembolisation, unit of blood transfusion, hospital cost and length of stay as secondary outcome.

Interventions

DRUGVonoprazan

Vonoprazan 20 mg oral every 12 hours (total 72 hours)

DRUGPPIs IV infusion

Pantoprazole 80 mg IV loading then 8 mg/hr
