Population Pharmacokinetics of Intravenous Paracetamol and Its Metabolites in Extreme Preterm Neonates in the Context of Patent Ductus Arteriosus Treatment.

ABSTRACT:

Aims

Our aim was to describe the pharmacokinetics of paracetamol and its metabolites in extreme preterm neonates in the context of patent ductus arteriosus treatment. Factors associated with inter-individual variability and metabolic pathways were studied. The association between drug exposure and clinical outcomes were investigated.

Methods

Preterm neonates of 23-26 weeks' gestational age received paracetamol within 12 h after birth. Plasma concentrations of paracetamol and its metabolites were measured throughout 5 days of treatment. Clinical success was defined as ductus closure on two consecutive days or at day 7. Aspartate aminotransferase and alanine aminotransferase levels were used as surrogates for liver damage.

Results

Data from 30 preterm neonates were avai
