Pharmacology as a science encompasses the following: the action of natural chemicals in the body; the origins and sources of drugs; their chemical structure and physical characteristics; their mechanisms of action; their metabolism and excretion; studies of their action on whole animals, isolated organs, tissues and cells, enzymes, DNA and other components of cells; ultimately studies of their actions in humans and their therapeutic uses. Pharmacology is also the study of the toxic effects of drugs and chemicals in the environment.
