Basic Pharmacokinetics. What is pharmacokinet- ics? Pharmacokinetics is the mathematics of the time course of Absorption, Distribu- tion, Metabolism, and . Basic Pharmacokinetics. To examine the concept of volume of distribution (vol- ume of distribution may be represented by “V” or “Vd”) further, let's return to our. Basic Pharmacokinetics. Introduction. Drugs, through dosage forms, are most frequently administered extravascularly and the majority of them are intended.

It must be mentioned that drug kinetics after distribution is characterized by the first-order rate constant. A compartment in pharmacokinetics is an entity that can be described by a definite volume and a concentration of a drug contained in that volume, which may be: Central Compartment The central compartment includes blood and the highly perfused organs and tissues such as heart, brain, lungs, liver, and kidney. In these organs, the administered drug usually equilibrates rapidly. Peripheral Compartment s This compartment s include s those organs that are less well-perfused such as adipose and skeletal muscle, and therefore the administered drug will equilibrate more slowly in these organs. The duration of the drug effect at the target tissue will often be affected by the redistribution from one compartment to another. For example, the general anesthetic drug, thiopental, which is a highly lipid-soluble agent, induces anesthesia within seconds owing to drug rapid equilibration between blood and brain. The duration of anesthesia is short due to drug redistribution into adipose tissue, which can act as a storage site, or drug reservoir, although thiopental is slowly metabolized.

Bourne DWA. Pharmacodynamics extends these observations by relating time-dependent kinetic processes to actual clinical drug effects including include both therapeutic and toxic drug actions. Therefore, pharmacodynamics is important because it is ultimately the discipline that relates drug pharmacokinetics to clinically relevant endpoints.
