This finding at least suggests that we need more data on the pharmacokinetics and pharmacodynamics of this drug in neonates during treatment with extracorporeal membrane oxygenation in order to ensure quality of care and safety and to promote evidence-based prescription. The implementation of population pharmacokinetic models can further increase both the feasibility of such studies and the relevance of the results generated. Although the general principles of clinical pharmacology apply to neonates and young infants the characteristics of this population warrant a specific approach. The relative body water content fat distribution and muscle mass are markedly different in foetal than in neonatal and paediatric groups. Almost all phase 1 and phase 2 hepatic clearance processes have a distinct isoenzyme-specific ontogeny whereas renal clearance in early neonatal life is limited and depends almost entirely on glomerular filtration rate the result of these factors is that the body s clearance of pharmacological agents evolves in a drug-specific age-dependent manner. Extracorporeal membrane oxygenation ECMO further affects the pharmacokinetics and pharmacodynamics PK PD of drugs. It is therefore mandatory that populationspecific data in neonates on drug-specific PK PD .
