Role of Pain Modulation in GERD Patients Who Failed Standard Dose Proton Pump Inhibitors (PPI)

August 18, 2010 updated by: University of Arizona

Role of Pain Modulation in GERD Patients Who Failed Standard Dose PPI.

The main objective of this study is to evaluate the role of pain modulation in GERD patients who fail to obtain clinical relief with standard dose (once daily) PPI. The study will compare the efficacy of 1) standard dose PPI plus low-dose tricyclic antidepressant (TCA) to, 2) double dose PPI to, 3) standard dose PPI and placebo to determine the relative symptom resolution and health related quality of life in GERD patients who fail standard dose PPI and are randomly assigned to one of these three groups.

Study Overview

Detailed Description

To evaluate the role of pain modulation in gastroesophageal reflux disease(GERD)patients who fail to obtain clinical relief with standard dose (once daily) proton pump inhibitor(PPI). The study will compare the efficacy; of 1)standard dose PPI plus low-dose tricyclic antidepressant (TCA) to, 2) double dose PPI to, 3) standard dose PPI and placebo to determine the relative symptom resolution and health related quality of life in GERD patients who fail standard dose PPI and are randomly assigned to one of these three groups.
