What is TDMx

Pharmacometrics applied to clinical practice

TDMx is an educational software for model-informed precision dosing. It provides a web-based application through which clinicians, clinical pharmacists, researchers and students can apply population pharmacokinetic modelling without requiring programming or modelling expertise.

Clinical practice

Educate to support real-world dosing decisions at the bedside, from routine patient data and TDM samples.

Vials and ampoules of injectable drugs

Clinical research

Simulate dosing regimens and evaluate target attainment for prospective and retrospective studies.

Education

Illustrate the principles of TDM and Bayesian forecasting; used for teaching at several universities.

How it works

From patient data to a dosing recommendation

1

Enter patient data

Patient covariates, dosing history and drug concentrations are entered directly in the browser; no local installation is required.

2

Choose a model

Users select from published, externally validated population PK models for the drug in question, or combine several through model averaging.

3

Get a recommendation

Dosing recommendations are generated probabilistically before treatment starts, or by Bayesian forecasting once TDM samples are available, both aimed at a defined PK/PD target.

Applications

Eight drugs, one modelling framework

Every TDMx module pairs a patient record with a library of peer-reviewed population PK models for that drug.

5 models

Standard dosing through renal replacement therapy and ECMO support.

Piperacillin

5 models

Intermittent, extended and continuous infusion, including renal replacement therapy.

Gentamicin

3 models

Adult, paediatric and neonatal populations, with extended-interval and traditional dosing.

Tobramycin

1 model

Paediatric and adult patients, with and without cystic fibrosis.

Amikacin

1 model

Critically-ill adult patients, including trauma and sepsis.

Factor VIII

1 model

Prophylactic dosing for severe and moderate haemophilia A.
