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. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models. Pharmacokinetics is an area of pharmacology concerned with the time course of absorption, distribution, metabolism and excretion (collectively ADME) of drugs from biological systems in order to. Pharmacokinetics (PK) is the study of the absorption, distribution, metabolism, and excretion (ADME) processes of a drug. Understanding PK properties is essential for drug development and precision medication. Pharmacokinetics is the study of how your body processes a drug, from the moment it enters your system to the moment it leaves. It’s often summed up as “what the body does to the drug,” which distinguishes it from pharmacodynamics, or “what the drug does to the body.” The definition of pharmacokinetics: “Pharmacokinetics is the study of kinetics of absorption, distribution, metabolism and excretion (ADME) of drugs and their corresponding pharmacologic, therapeutic, or toxic responses in man and animals.”¹ Pharmacokinetics is the branch of pharmacology devoted to understanding what the body does to a drug once it has been administered. This entails a detailed look at four main processes collectively known by the acronym ADME: Absorption, Distribution, Metabolism, and Excretion. Pharmacokinetics is defined as the quantitative analysis of the processes of drug absorption, distribution, and elimination that determine the time course of drug action. Pharmacokinetics, sometimes described as what the body does to a drug, refers to the movement of drug into, through, and out of the body—the time course of its absorption, bioavailability, distribution, metabolism, and excretion.
