Pharmacokinetics is the study of the rate of drug absorption, distribution, and elimination. Each of these processes is associated with one or more pharmacokinetic parameters that determine the rate and extent of the process.

Pharmacokinetic modeling is used to derive the mathematical expression that utilizes the pharmacokinetic parameters to describe the drug profile in the body.

Pharmacokinetic simulation is a tool that can be used to visualize how the change in each of the pharmacokinetic parameters affects the drug profile in the body.
