U.S. brand and generic prescription drug revenue 2005-2018

This statistic compares brand drug prescription revenues of branded and unbranded generics in the United States from 2005 to 2018. In 2005, some 81 percent of total U.S. prescription revenues were made through brand name medications. However, this share decreased to some 71 percent in 2013, but increased again to nearly 79 percent until 2018. Generics are copies or equivalents of once patent protected drugs, containing the same active ingredient, in the same amount, in the same form, dissolving at the same rate in equal amounts like the original.
