High Dose Oral Omeprazole Versus Standard Continuous Intravenous Pantoprazole in Patient With Peptic Ulcer Bleeding and Undergo Successful Therapeutic Endoscopy; Non-inferiority Randomized Controlled Trial

Overview

Peptic ulcer bleeding is the most common etiology in upper gastrointestinal bleeding all over the world. After endoscopic treatment, proton pump inhibitor (PPI) is recommended to prevent re-bleeding. Intravenous PPI is recommended as a standard treatment. In the past, there were many trials showing the efficacy of high-dose oral PPI after endoscopic hemostasis but most were industrial sponsor which assessing an expensive PPI. Moreover, the number of patients in those studies were insufficient to confirm a non-inferiority outcome in term of rebleeding by using oral PPI. This study will evaluate a high-dose, local-made PPI (omeprazole) in peptic ulcer treatment after successful endoscopic hemostasis compared to standard IV PPI continuous drip in term of rebleeding, as well as 24-hour gastric pH monitoring.

Interventions

  • Drug High-dose oral omeprazole
    Local made oral omeprazole 40 mg twice daily will be prescribed for 72 hours after randomization.
  • Drug Standard IV PPI
    Pantoprazole 8mg/hour IV continuous drip will be prescribed for 72 hours after randomization

Primary outcome measures

  • Rate of 3-day peptic ulcer rebleeding [Time frame: 3 days]
Secondary outcome measures (2)
  • Percentage of 24-hour gastric pH above 6 [Time frame: 3 days]
  • Rate of 30-day peptic ulcer rebleeding [Time frame: 30 days]

Eligibility criteria

Inclusion criteria

Exclusion criteria
