I'd like to point you all in the general direction of RxWiki.
RxWiki is a wiki that only licensed pharmacists are permitted to edit; it's being compiled as a resource for anyone, but it's generally being directed at patients. I've been browsing it a bit myself, and I'm very impressed so far. Apparently they have a panel of pharmacists who review everything and approve articles, and they're endorsed by the APhA.
I do take serious issue with their little blurb that's currently on the front page about placebos. The information presented in the articles seems solid, though.
Check it out. I think it might just become my new source for links whenever I cite a drug name.
