Comment Re:Drug Patent (Score 1) 160
I was wondering how long a drug patent lasts right now and if it is tied at all to how long it took to research whatever the drug patent is for?
Drug patent's don't expire anymore, and if a generic is available they are able to restrict it's purchase in the US.
Modafinal is the generic name and can't be purchase in the US, Provigil is the brand name and was due
to lose it's patent in 2012. Nuvigil was released at that time and I can't find a reason but the patent has
been extended to Provigil to some time in the far future
Modafinal http://en.wikipedia.org/wiki/Modafinil > Provigil >
Nuvigil http://en.wikipedia.org/wiki/Armodafinil generic is Armodafinil
Both are the same chemical structure. Not sure if you can purchase Provigil anymore, Nuvigil is cost prohibitive - say $20 a pill in the US.
