The pharmaceutical sciences are a group of interdisciplinary areas of study concerned with the design, action, delivery, disposition, inorganic, physical, biochemical and analytical biology, epidemiology, statistics, chemometrics, mathematics, physics, and chemical engineering, and applies their principles to the study of drugs. The pharmaceutical sciences are further subdivided into several specific specialties, with four main branches: Pharmacology: the study of the biochemical and physiological effects of drugs on human beings. Pharmacodynamics: the study of the cellular and molecular interactions of drugs with their receptors. Simply "What the drug does to the body" Pharmacokinetics: the study of the factors that control the concentration of drug at various sites in the body. Simply "What the body does to the drug" Pharmaceutical toxicology: the study of the harmful or toxic effects of drugs. Pharmacogenomics: the study of the inheritance of characteristic patterns of interaction between drugs and organisms. Pharmaceutical chemistry: the study of drug design to optimize pharmacokinetics and pharmacodynamics, and synthesis of new drug molecules.
