In this episode of Communicable, Amy Legg (Brisbane, Australia), Rekha Pai Mangalore (Melbourne, Australia) & Angela Huttner (Geneva, Switzerland) return for the third part of the ‘We will make you love PK/PD’ series. The hosts are joined by two experts, Amanda Gwee (Melbourne, Australia) & Sebastian Wicha (Hamburg, Germany), to dive into an important application of PK/PD: model-informed precision dosing (MIPD), and how it allows for more informed, individualised dosing decisions. The episode also covers the open-access educational tools, KidsCalc and TDMx, developed by Gwee and Wicha respectively, and the steps clinicians can take to put MIPD into practice, keeping the individual patient at the centre of dosing decisions.
