INTRODUCTION Acetaminophen (paracetamol) is mainly metabolized via glucuronidation and sulphation, while the minor pathway through cytochrome P450 (CYP) 2E1 is held responsible for hepatotoxicity. In obese patients, CYP2E1 activity is reported to be induced, thereby potentially worsening the safety profile of acetaminophen. The aim of this study was to(More)
Predicting target site drug concentration in the brain is of key importance for the successful development of drugs acting on the central nervous system. We propose a generic mathematical model to describe the pharmacokinetics in brain compartments, and apply this model to predict human brain disposition. A mathematical model consisting of several(More)
Pain cannot be directly measured in neonates. Therefore, scores based on indirect behavioural signals such as crying, or physiological signs such as blood pressure, are used to quantify neonatal pain both in clinical practice and in clinical studies. The aim of this study was to determine which of the physiological and behavioural items of 2 validated pain(More)
Obtaining pharmacologically relevant exposure levels of antibiotics in the epithelial lining fluid (ELF) is of critical importance to ensure optimal treatment of lung infections. Our objectives were to develop a model for the prediction of the ELF-plasma concentration ratio (EPR) of antibiotics based on their chemical structure descriptors (CSDs). EPR data(More)
