Introduction Pharmacokinetics provides a mathematical basis to assess the time course of drugs and their effects in the body. It enables the following processes to be quantified: Absorption Distribution Metabolism Equations/Useful_pharmacokinetic_equ_5127 2 Constant rate infusion Plasma concentration (during infusion) C k CL 0 1 e kte Plasma concentration (steady state) C k CL 0 Calculated clearance (Chiou equation) CL k CC Vd C C CC t t 2 2 0 12 12 12 21 Short-term infusion Peak (single dose) C Introduction to Pharmacokinetics and Pharmacodynamics Pharmacokinetics is currently defined as the study of the time course of drug absorption, distribution, metabo-lism, and excretion. Clinical pharmacokinetics is the application of pharmacokinetic principles to the safe and effective therapeutic management of drugs in an individual patient.

Nonlinear pharmacokinetics is the characteristic of drugs that briefs that the absorption and bioavailability can cause increases in drug concentrations that are disproportionately high or low relative to the change in dose.

For a drug with linear PK, we would expect that a 2-fold increase in dose would result in a 2-fold increase in drug exposure. When the dose of EPO is doubled from 1 μg/kg to 2 μg/kg, the exposure increases more than 2-fold. ◼Nonlinear pharmacokinetic drugs pose a challenge in therapy management due to their complex nature.
