Generic Adderall XR

The question is: can generic Adderall XR be found on the market legally? It can. At least since 2006, when Shire Pharmaceuticals agreed to sell her rights for this brand name to another company called Duramed Pharmaceuticals. Since then, the medication has become available under generic name of "mixed amphetamine salts". Shire intended to retain exclusive patent rights until the patent for the "Adderall" brand expired in 2018. However, Shire first sold Adderall (instant release) to Barr Pharmaceuticals and then let Barr manufacture the generic for Adderall extended-release, too. Also, a settlement has been reached between IMPAX Laboratories and Shire Laboratories Inc., a subsidiary of Britain's Shire Pharmaceuticals in the United States, so IMPAX will be able to sell generic Adderall XR in the United States at least until January 1, 2010. Also, in case of another generic version of Adderall XR being launched, IMPAX may be permitted to enter the market as Shire's authorized generic.
