You want to know why conservatives are so opposed to single-payer healthcare and importing drugs from Canada? Their connections with these companies and their ensuing drive to protect these kinds of business practices is one of the reasons why. And this is hardly the only company that does this or drug that this is done with.
I cringe when I hear people claim that they voluntarily request brand-name drugs over generics because they're "higher quality" or "manufactured to better standards." These name-brand drug companies are mucking around with what's in your pill for the sole purpose of jacking up their profits!
Right. These things happen all the time -- other recent examples are Prilosec/Nexium, Provigil/Nuvigil. They change the additives for a different dosage, or switch from a racemic mixture (both mirror image molecules, one active and the other inert) to only one isomer (only the clinically active version of the molecule).
