From Animals to Algorithms: Leveraging PK/PD Models to Drive the 3R’s in Pharmacology

In the pursuit of ethical and efficient drug development, the scientific community continues to embrace the 3R’s principle — Replacement, Reduction, and Refinement — to minimize the use of animals …

Exploration of intra-individual variability in a multiple dose study during NCA

A non-compartmental analysis (NCA) is commonly performed to analyse the data of a pharmacokinetic study. It is an easy way of getting your pharmacokinetic parameters (such as the Cmax, tmax, …

Parallel fast-slow absorption – Modelling the Tortoise AND the Hare

Introduction Unsurprisingly, the absorption of drugs is a complex process. Should you try a first-order input? Zero-order? Both?! Especially when a bias in the model fit of your absorption phase …

Applying MAP Bayes estimation for therapeutic drug monitoring (TDM) in R with mrgsolve

The development of population PK (and PD) models enable the use of individual Bayesian dose optimization. One could use the included covariates to derive the dose of an individual but …

Simulating the equi-dosing regimen region in R using mrgsolve – a bottom-up approach

Acknowledgments The idea for this post was based upon the research by Dr. Lloyd Bridge, presented at the British Pharmacological Society meeting December 2018. and published in October 2020 in …

How (not) to report pharmacokinetic data

The correct reporting of pharmacokinetic data can provide a tremendous amount of information on the clinical pharmacological characteristics of a drug. Small studies with a limited number of plasma samples …

Inter-individual and/or inter-occasion variability: what can we quantify in our models and what is the impact on simulations

Introduction We are not all the same. We know that there is variability originating from physiological differences in the pharmacokinetic and pharmacodynamic (PK/PD) processes between individuals in a population, also …

Calculating the power of covariates in population non-linear mixed effects models: the Monte Carlo Mapped Power approach

This post is based on the work of, among others, Camille Vong and the hands-on course about the MCMP given by Rob ter Heine and Elin Svensson. Read and cite …

Flawed study design of parent-metabolite pharmacokinetic studies – the prove is in the pee

How do we develop a ‘standard’ population PK model? We obtain blood/plasma concentrations over time of the drug of interest, in multiple individuals, and we apply our population NLME modelling …
