  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
