Introduction
The information provided by pharmacokinetics is important in the discovery of new drugs and in screening drug candidates. It helps in drug research and can determine the concentration of a drug present in the body. The discovery of new medicines not only depends on pharmacological activity but on pharmacokinetic parameters as well. Pharmacokinetics includes absorption, distribution, metabolism and execration (ADME). Absorption is the absorbing of a drug in the blood stream. There are two types of absorption, passive and active. The physico-chemical properties are responsible for passive transportation while the active transportation determines the binding of a molecule to the target site. ...
