This patent describes an extended release oral amphetamine tablet composition containing a combination of amphetamine-cation exchange resin complexes and uncomplexed amphetamine.

USPTO Abstract

An oral amphetamine extended release solid dose is described. The compositions contain a combination of an uncoated amphetamine-cation exchange resin complex, a barrier coated amphetamine—cation exchange resin complex—matrix, and an uncomplexed amphetamine, wherein one or more of these components contains blends of different forms of amphetamines. Either the modified release coated and/or the uncoated amphetamine—cation exchange resin complex may have two forms of amphetamine in a complex with a single cation exchange resin. Following administration of a single dose of the composition, a therapeutically effective amount of amphetamine is reached by about one hour and the composition provides at least a thirteen hour effect post-dose.
