Hi L
I don't think the generics companies always manufacture the drug substance, they often just make the tablets etc. AFAIK, the source of the drug itself is sometimes the same for both the brand and the generic.
Manuafacturing racemic drugs (eg. citalopram) which consist of 50% R-enantiomer and 50% S-enantionmer is probably relatively basic. The manufacture of single-isomer products such as escitalopram is technically more challenging.
