More specifically, it is the study of the interactions that occur between a living organism and exogenous chemicals that alter normal biochemical function. If substances have [[medication|medicinal]] properties, they are considered [[Pharmaceutical drug|pharmaceuticals]]. The field encompasses [[drug]] composition and properties, [[interaction]]s, [[toxicology]], therapy, and medical applications and antipathogenic capabilities. Pharmacology is not synonymous with [[pharmacy]], which is the name used for a profession, though in common usage the two terms are confused at times. Pharmacology deals with how drugs interact within biological systems to affect function. It is the study of drugs, of the body's reaction to drugs, the sources of drugs, their nature, and their properties. In contrast, pharmacy is a medical science concerned with the safe and effective use of medicines.
