Condition(s) targeted: Apea of Prematurity

Phase: N/A

Status: Enrolling by invitation

1. Population pharmacokinetics : The purpose of this study is

- to investigate the population pharmacokinetics of theophylline in premature Korean

infants and to assess the influence of demographic and clinical covariates. 2. Metabolomics : The purpose of this study are

- to predict serum theophylline levels and to assess CYP1A2 activities in premature

infants by analyzing urinary metabolites of theophylline

- to examine which factors affect clearance of theophylline and CYP1A2 activity in

premature infants
