High-dose oral omeprazole for treating peptic ulcer bleeding

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

Not applicable Interventional King Chulalongkorn Memorial Hospital · NCT04394663

This study tests if taking high-dose oral omeprazole can help prevent re-bleeding in patients with peptic ulcers just like the more expensive intravenous treatments.

What this trial studies

This study evaluates the effectiveness of high-dose oral omeprazole compared to standard intravenous proton pump inhibitors (PPIs) in preventing re-bleeding in patients with peptic ulcer bleeding after successful endoscopic treatment. It aims to determine if the oral formulation can provide similar outcomes to the more expensive intravenous option. The study focuses on patients with specific types of peptic ulcers classified as high risk for re-bleeding. By using a locally made PPI, the study also seeks to assess cost-effectiveness in treatment.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with high-risk peptic ulcer bleeding as identified by specific endoscopic findings.

Not a fit: Patients with low-risk peptic ulcer bleeding or other types of gastrointestinal bleeding unrelated to peptic ulcers may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accessible and cost-effective treatment option for patients with peptic ulcer bleeding.

How similar studies have performed: Previous studies have shown the efficacy of high-dose oral PPIs, but this study aims to confirm non-inferiority with a locally made option, making it a novel approach.
