AZ rep here.... we were going to launch dutoprol over 4 years ago when it was approved and when Toprol-xl went generic but the marketing team and bean counters after running the numbers felt it was not going to pay for itself. AZ is desparate and its long term plan is to be distinct form other companies based on sales force effectiveness.... aka "beating you and training you to death" . Giving you so many rules to follow that are not even required by the fda and making any drug impossible to launch.
All of the pipe line drugs that had/have a true novel benefit have not made it to market except Brilinta.
I launched Toprol-xl. You give you AZ rep a call, some of the " old timers " in your market might be able to help you out.
Also AZ is tring to be the first company to completely launch a drug with contract sales force and be successful... they will never realize the combo pill of two generics with today's economy and regulatory environment is the stupidest idea ever. The will blamre you or Publicis...get ready.
