Aim:Current enoxaparin dosing guidelines in children are based on total bodyweight. This is potentially inappropriate in obese children as it may overestimate thedrug clearance. Current evidence suggests that obese children may require lower ini-tial doses of enoxaparin, therefore the aim of this work was to characterise the phar-macokinetics of enoxaparin in obese children and to propose a more appropriatedosing regimen.Methods:Data from 196 unique encounters of 160 children who received enoxa-parin treatment doses were analysed. Enoxaparin concentration was quantified usingthe chromogenic anti factor Xa (anti-Xa) assay. Patients provided a total of 552 anti-Xa samples. Existing published pharmacokinetic (PK) models were fitted …

Aims The aim of this study was to evaluate the population pharmacokinetics (PopPK) of olanzapine in children and devise a model-informed paediatric dosing scheme. Methods The PopPK of olanzapine was characterized using opportunistically collected plasma samples from children receiving olanzapine per standard of care for any indication. A nonlinear mixed effect modelling approach was employed for model development using the software NONMEM (v7.4). Simulations from the developed PopPK model were used to devise a paediatric dosing scheme that targeted comparable plasma exposures to adolescents and adults. Results Forty-five participants contributed 83 plasma samples towards the analysis. The median (range) postnatal …

We have identified distinct histamine pharmacodynamic response phenotypes in children with allergic disease utilizing histamine iontophoresis with laser Doppler (HILD). These response phenotypes may be relevant in guiding therapeutic decision making for agents targeting the allergic response pathways. However, the reliability of these response phenotypes has not been assessed. Therefore, we performed HILD in children with allergic rhinitis and/or asthma on two to three separate occasions. HILD response-time data were analyzed in NONMEM using a linked effect PKPD model. Examination of observed vs. classified response phenotypes predicted response plots and the sum of residuals. The intraclass correlation coefficient (ICC) was …
