What is Armodafinil?

Well, in the simplest of terms, Armodafinil is a ‘pure form’ of the popular Eugeroic drug- Modafinil. Chemically, both Armodafinil and Modafinil are the same compounds. However, they differ markedly in their spatial structure.


Modafinil has two structurally different molecules. One is a structural mirror image of the other. It is a very common chemical phenomenon called Isomerism. The two isomers of a compound, Modafinil, in this case, are mirror images of each other.
