Overview
Brief Summary
A single-center, randomized, open-label, crossover study to evaluate the pharmacokinetic drug-drug interaction and safety of the quadruple therapy with Anaprazole 20mg/Amoxicilin 1000mg/Clarithromycin 500mg/Bismuth Potassium Citrate 0.6g in healthy Chinese male subjects.
Detailed Description
The study composed of 2 cohorts, using a 4\*4 or 2\*2 crossover design in cohort 1 and 2, respectively. 4 rotating treatment sequences in cohort 1, each treatment sequence comprised 4 treatment periods, separated by a washout period of 9 days; 2 rotating treatment sequences in cohort 2, each treatment sequence comprised 2 treatment periods, separated by a washout period of 9 days
