Condition(s) targeted: Stomach Ulcer

Intervention: Rebamipide (Drug); Omeprazole (Drug)

Phase: Phase 4

Status: Completed

Summary

The purpose of this study is to evaluate the ulcer healing efficacy of rebamipide in comparison with omeprazole in Helicobacter pylori-positive gastric ulcer after eradication therapy.

Clinical Details

Official title: A Comparative Study on the Healing Effects of Rebamipide and Omeprazole in Helicobacter Pylori-positive Gastric Ulcer After Eradication Therapy

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Primary outcome: Gastric ulcer healing rate

Secondary outcome:

Gastric ulcer healing rate in cases with successful H.pylori eradication and H.pylori eradication failure (12 weeks after administration of the study medication.)

Serum gastrin level

Economical efficiency

Detailed description: 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.
