Pharmacokinetics refers to the absorption, distribution, metabolism, and exertion of a drug. These four processes determine the intensity and duration of a drug's action. Each drug has unique pharmacokinetics characteristics. Pharmacology is the science of drug effects. It deals with all drugs used in society, legal and illegal, prescription and nonprescription.
