Abstract

OBJECTIVE:

This prospective, randomized, controlled, head-to-head study was conducted to compare the efficacies of esomeprazole- and pantoprazole-based triple therapies for Helicobacter pylori eradication.

METHODS:

From January 2002 to October 2003, 200 H. pylori-infected patients were randomly assigned to undergo twice daily treatment with esomeprazole 40 mg (n = 100) or pantoprazole 40 mg (n = 100) combined with clarithromycin 500 mg and amoxicillin 1 g for 1 wk (ECA and PCA groups, respectively). Follow-up endoscopy was performed at 8 wks after the end of treatment to assess the treatment response.

RESULTS:

Intention-to-treat analysis demonstrated a significantly higher eradication rate for the ECA group than for the PCA group (94%vs 82%, respectively, p= 0.009). Per-protocol analysis also showed similar results (97%vs 84%, p= 0.003). Both groups had similar frequencies of adverse events (15%vs 24%) and drug compliance (97%vs 96%). Multivariate analysis disclosed that the use of esomeprazole (OR: 1.56, 95% CI, 1.11-2.19) and good compliance 7.39 (95% CI, 1.27-42.95) were independent predictors of treatment success. Alcohol drinking was an independent predictor of eradication failure (OR: 0.18; 95% CI, 0.06-0.54).

CONCLUSION:

Esomeprazole-based triple therapy demonstrated a higher eradication rate than pantoprazole-based regimen. The differences in eradiation efficacies between the two study groups may be related to the more powerful acid inhibition effect and stronger anti-H. pylori activity of esomeprazole compared to pantoprazole.
