This study is not yet open for participant recruitment.

Verified by Osaka University, November 2005

First Received: March 6, 2006 Last Updated: March 9, 2006 History of Changes

Sponsor:	Osaka University
Information provided by:	Osaka University
ClinicalTrials.gov Identifier:	NCT00299845

Purpose

Proton pump inhibitors are administered to children as off-label use in Japan. The purpose of this study is to evaluate the effects of CYP2C19 genotypes on pharmacokinetic /pharmacodynamic profiles of PPI in children. The results will provide the beneficial information for the individualized medicine of PPI in children.
