Rebamipide in Combination With Esomeprazole in the Management of Asian Patients With Functional Dyspepsia

January 4, 2016 updated by: University of Malaya

Rebamipide in Combination With Esomeprazole in the Management of Asian Patients With Functional Dyspepsia: a Multi-national, Randomised, Double-blind, Placebo-controlled Study

This is a multi-Asian-centre randomised controlled trial of Rebamipide alone vs Rebamipide with Esomeprazole in the treatment of adult patients with Functional Dyspepsia. The hypothesis is that a combination therapy is superior to mono-therapy in the control of patients' symptoms and quality of life improvement.
