Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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
