PK/PD MODELING (PHARMACOKINETIC/PHARMACODYNAMIC MODELING) (alternatively abbreviated as PKPD or PK-PD modeling) is a technique that combines the two classical pharmacologic disciplines of pharmacokinetics and pharmacodynamics . It integrates a pharmacokinetic and a pharmacodynamic model component into one set of mathematical expressions that allows the description of the time course of effect intensity in response to administration of a drug dose.

There are a variety of PK/PD modeling approaches, but there are only five major classes:

* Direct link PK/PD models * Indirect link PK/PD models * Indirect response PK/PD models * Cell Lifespan models * Complex response models
