I didn't see the article from the link, but the pharmaceutical lobby wouldn't allow something like that to pass, hydro is one of the top three prescribed drugs in the country.
That site is full of wrong info, for example it said OC generic is only available in an 80mg dose,
wrong, Endo, Teva, Watson and Dava/Impax have been making
Oxycodone ER in 10, 20, 40 and 80mgs for years.
