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.
The brand name is developed by the company requesting approval for the drug and identifies it as the exclusive property of that company. When a drug is under patent protection, the company markets it under its brand name.ot all off-patent drugs have generic versions. Sometimes a drug is too hard to duplicate, or adequate tests are not available to prove that the generic drug acts the same as the brand-name drug. Sometimes the market for the drug is so small that producing another version does not make good business sense.
