It’s ADDeral, and has roughly twice the potency of Ritilin. Actually adderal is basically Dexedrine (which I take for my ADD), and just a mirror image of the molecule. Ritilin never did much of anything for me, but Dexedrine works quite well.
Ritilin is not an amphetamine, it’s a stimulent. The amphetamines are: Benzedrine, Dexedrine, and Methedrine (speed), in the order of least to most potent. The effects of Ritilin (methylphenidate) are very similar to those of the amphetamines, though the mechanism of action of the drugs are different.
