Pharmacokinetics-pharmacodynamics (PK/PD)

Definition:

Integration of pharmacokinetic and pharmacodynamic data to understand how a drug is likely to be distributed through the body over time and the access it will have to its molecular target. This understanding provides the basis for dosing strategies.

Typically, PK/PD modelling is used to simulate how a drug is distributed across different tissues (or ‘compartments’) over time. These models can be used to estimate drug concentrations at different body sites for different dosing regimens and drug effect.
