Patent Ductus Arteriosus
Conditions
Brief summary
The investigator's purpose is to study the population pharmacokinetics of paracatamol and ibuprofen in neonates with patent ductus arteriosus (PDA) and assess the feasibility of dosage individualization.
Detailed description
The investigator's purpose is to study the population pharmacokinetics of paracatamol and ibuprofen in neonates with patent ductus arteriosus (PDA) and assess the feasibility of dosage individualization. In this study, the investigator will detect drug concentration in plasma and other clinical test to construct population pharmacokinetic models.
Interventions
