Does anyone have any information on Vyvase? According to what I am reading it just gained approval in the states in April of this year and as Addy's patent expires the company, Shire is looking to capture a significant part of their market share. I read something that said that insouflating would not work. Does anyone have any first person anecdotal evidence about this? It's being marketed to the adult portion of the ADHD market. Seems they did something clever and made the release slower by adding an aminoacid that has to be hydrolized before the drug is available to yoour body. I think the generic is lis-dextroamphetamine
