What this trial studies

This observational study evaluates the effectiveness of a dual therapy regimen combining tegoprazan, a potassium-competitive acid blocker, and amoxicillin for eradicating Helicobacter pylori infections. The approach aims to improve treatment outcomes by enhancing the stability and activity of amoxicillin in a higher gastric pH environment. The study will assess the success rate of H. pylori eradication and patient compliance with the treatment protocol over a specified duration. Participants will undergo gastroscopy and H. pylori testing as part of the evaluation process.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 20 to 80 who can undergo gastroscopy and H. pylori testing.

Not a fit: Patients with severe systemic diseases, advanced chronic liver disease, or a history of gastric surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a highly effective alternative for patients suffering from H. pylori infections, especially in cases where traditional therapies have failed.

How similar studies have performed: Previous studies have shown promising results with similar dual therapy approaches, indicating potential for success in this novel treatment regimen.
