6 th Annual Primary Care Spring Conference Thursday, April 12, 2012 FDA FDA Data on Generics • FDA recently evaluated 2,070 human studies conducted between 1996 and 2007. These studies compared the absorption of brand name and generic drugs into a person’s body. These studies were submitted to FDA to support approval of generics. The average difference in absorption into the body between the generic and the brand name was 3.5 percent. Some generics were absorbed slightly more, some slightly less. This amount of difference would be expected and acceptable, whether for one batch of brand name drug tested against another batch of the same brand, or for a generic tested against a brand name drug. In fact, there have been studies in which brand name drugs were compared with themselves as well as with a generic. As a rule, the difference for the generic-to-brand comparison was about the same as the brand-to-brand comparison. – Davit et al.

Center for Drug Evaluation and Research FDA FDA Data on Generics • FDA requires generic drugs to have the same quality and performance as brand name drugs. • Research shows that generics work just as well as brand FDA name Facts drugs. about Generic Drugs – A study evaluated the results of 38 published clinical trials that compared cardiovascular generic drugs to their brand name counterparts. There was no evidence that brand name heart drugs worked any better than generic heart drugs • Kesselheim et al.
