Here's an interesting site you might want to take a look at. Although designed for doctors, the information is fascinating for the layperson as well. The MGH Institute of Health Professions, an academic affiliate of Massachusetts General Hospital, launched a new continuing education documentary and interactive websitedesigned to educate doctor/prescribers about drug industry influence. Ironically, the program is funded by Pfizer as a result of the Neurontin settlement.
In particular, you might want to check out their documentary film modules that explain how drugs get approved and marketed -- and the influence pharmaceutical companies have on those outcomes. It's surprisingly pointed, considering that it came out of mainstream medicine. Then again, the documentaries were produced by former pharmaceutical rep, now filmmaker and consumer health advocate, Kathleen Slattery-Moschkau.
