With the help of the local Merck rep, I actually had a conversation with the "medical director" at Medco, a physician, years ago before it was spun off from Merck. He was "astounded" by my comments and negative impression of the way Medco functioned, especially their pressure to change to formulary meds. The guy promised changes. We all can see how that worked.
Shortly thereafter, news of class action lawsuits broke. More recently, Merck was found to have conspired to cover up info about Vioxx toxicity.
Big Pharma -- rotten to the core.
