Adderal was on the market as Orbitol till the 70's, was pulled because of abuse. Was re-introduced as Adderal as of late.
Adderal is a 50/50 mix of D and L amphetamine.
D and L refer to isomers, isomers mean a chemical with the same # of atoms, but in a different arrangement. D is "left handed" arrangement, L is the right. Biology mostly runs on D isomers, the universe is rather left handed, though there are exceptions, like the aminos. Look on the net about isomers, you really need graphics to understand this ! Many times the L is not active in humans, or is not useful, or has negative side effects.Dex is all d-amphetamine, proven to be active in humans. L-amphetamine has some action, but tends to have more negative effects. Reported are: makes you more shakey, dysphoria, sweaty, ect.
The D vers is more smooth feeling."Least patentable difference" is the least chemical difference you can change a compound from the patent to get another patent. In this case it is the addition of L-amphetamine, and a few other things.
