Effect of Rabeprazole and Lansoprazole on Reflux Esophagitis in Relation to CYP2C19 Genotype Status: A Prospective, Randomized, Multicenter Study
Abstract
The purpose of this study is to compare the treatment effects of rabeprazole and lansoprazole depending on the genotyping (process of determining the genetic constitution) of CYP2C19 in treating reflux esophagitis (caused by gastroesophageal reflux; deterioration of the protective lining on the inner wall of the lower esophagus); and to evaluate the cure rate of reflux esophagitis on endoscopy (a thin flexible tube with a microscopic camera at the end which is passed down your throat into the esophagus, stomach, and duodenum) after treatment with rabeprazole and lansoprazole.
Conditions: Reflux Esophagitis.
Primary outcome: Percentage of Participants Completely Cured of Reflux Esophagitis Evaluated by Endoscopy Based on CYP2C19.
Enrollment: 217 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 217 participants or records.
