Yah, I'd love to have Bayer as they made it awhile ago, but Purdue had been making it as they're shady enough to understand that they are simply pushing it as a PDF, while they have a position to price gouge. I figure that it's hand in hand with the Oxycontin ethic.
Anyways, Bronkaid seems to be weaker because it's a preparation coated with calcium so that it doesn't upset the little tummies out there. At least that's part of it, like taking ephedrine with a glass of milk.
