I'm doing a presentation on generic versus brand name drugs and I was wondering if anyone can recommend any good and reliable websites on the topic. I found the usual web md and such, but as professionals or soon-to-be professionals of this field, are the two really the same? I've heard everything from the two are exactly the same except for the manufacturers and some people told me that the only difference are the fillers they use for the pills. What are fillers? And where can I find more information on this issue? Thanks.
