VRX has an agreement with Walgreen's, but does Valeant have a relationship with any of the three big pharmacy benefits managers in the U.S., namely Express Scripts, CVS Caremark (CVS drug stores are a direct competitor of Walgreen's), and OptumRx....?....not sure how much these organizations influence drug company profitability and distribution, or how vital they are in volume sales.......
