ClinConnect Summary

This study is designed to evaluate the ulcer healing efficacy of rebamipide administered following the eradication therapy in comparison with the well known PPI, omeprazole. This is a double-blind, comparative study which is expected to prove the role of rebamipide in gastric ulcer healing after the eradication therapy. This study may contribute to further clinical research on a new type of ulcer treatment by looking at the treatment modality based on the enhancement of defensive factors.
