Brief Summary:
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.
