This is the site that came to mind when I saw your question. It is not quite what you are asking for, but maybe it will work if nothing better comes along.
I have never asked any questions about its (the site's) utility before because of the inevitable trash talk that would generate from my "fan club" about trying to tell professional insurance agents how to do their business.
When I put georgia in the state and duloxetine in the search by drug name box and click search:
the drug box area comes up with Select A Drug==>:
At the far right of the drug entry box is a down arrow which you can click, then choose one of the formulations of the drug.
One should note that the Q1 data is drawn from Medicare, so it is not an independent cross check on information, but only a tool which may be easier to use in some respects.
