After reading this article you will learn about the concept and types of pharmacokinetic models. Concept of Pharmacokinetic Models: Drugs remain in dynamic state within the body and drug events often happen simultaneously. In order to describe a complex biologic system, assumptions are made concerning the movement of drugs. The mathematical models are used to […]
The plasma level time curve is plotted after measured drug concentration in plasma of an animal at different time intervals. The concentrations of drug in each plasma sample are plotted on an ordinary graph paper against the corresponding time at which the plasma samples were collected. As the drug reaches in systemic circulation, plasma drug […]
This article throws light upon the three main types of pharmacokinetic variables of drugs. The variables are: 1. Plasma Half-Life (t1/2β) 2. Volumes of Distribution 3. Total Body Clearance (CIB). Type # 1. Plasma Half-Life (t1/2β): Half-life is defined as the time of declining the initial plasma drug concentration by half. It is also known […]
