I'm doing drug research for my pharmacy tech class and I'm not sure what websites provide dates and such for drugs with their patents and history surrounding the drug. I'm not looking for drug information such as what it does and what it looks like I can find that info at drugs.com but I need a website with the information BEHIND the drug...when it was created...when does their patent expire...stuff like that. Please only real answers/links! I can't use wikipedia! Thanks it's much appreciated!
