Provigil (modafinil) and Nuvigil (armodafinil) are chemically very similar.  Cephalon, the manufacturer of both drugs, claims that Nuvigil's effects are longer lasting.  They've never been tested in head-to-head clinical trials but Cephalon says this was determined by comparisons of their concentrations in plasma. 

 

Skeptics think the main reason Cephalon has introduced this new drug is because Provigil's patent protection will run out in 2012, allowing generic competition.  Nuvigil will have patent protection until 2023.
