Generic (official) name. Brand (proprietary or trademark or trade) name. For example, phenytoin is the generic name and Dilantin is a brand name for the same drug. The generic name is assigned, in the United States, by an official bodyâthe United States Adopted Names (USAN) Council.
A generic drug is a copy of a brand name drug whose patent has expired. The original manufacturer of a drug receives a patent on the drug and is the only manufacturer who can produce and sell the drug during this patent period. Once the patent expires, other manufacturers may produce and sell the drug. These manufacturers usually sell the drug under its common or generic name. Most drugs have three names: 1  a chemical name. 2  a generic name. 3  a brand name.
