Drug Nomenclature

Drugs generally have three names: a chemical name, a nonproprietary (generic) name, and a proprietary (trade) name. The chemical name describes the chemical structure. For example, 7-chloro-2-methylamino-5-phenyl-3-H-1,4-benzodiazapine-4-oxide is the chemical name for a benzodiazepine called chlordiazepoxide. Chlordiazepoxide is the nonproprietary or generic name, which is given to a drug when it has been demonstrated to have a therapeutic use. A proprietary or trade name is given by a drug company when the drug is patented. Two trade names for chlordiazepoxide are Librium and Mitran.
