What this trial studies

This clinical trial aims to compare the effectiveness of tegoprazan versus lansoprazole in healing bleeding peptic ulcers in patients from the Indonesian population. Participants will be randomly assigned to receive either tegoprazan 50 mg or lansoprazole 30 mg daily for two weeks, with endoscopic examinations conducted before and after treatment to assess healing rates. The study will also monitor the safety and occurrence of adverse effects associated with both medications.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with upper gastrointestinal bleeding due to peptic ulcers confirmed by gastroscopy.

Not a fit: Patients with allergies to tegoprazan or lansoprazole, those with gastric or duodenal cancer, or individuals with significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from bleeding peptic ulcers.

How similar studies have performed: While proton pump inhibitors have been widely studied, the use of potassium-competitive acid blockers like tegoprazan is relatively novel, and this study aims to evaluate its effectiveness compared to established treatments.
