Diabetes Go

What are the top 20 diabetes medications?

What are the most popular medications for diabetes, in terms of recent sales, number of patients, or some similar measure? I am interested in data for both oral medications, insulins, and other types of medication. The purpose of the question is to find out which meds out of those available are the most used and the most popular at the present time. I am not looking for treatment advice, and I am not looking for the names of just one or two medications. Thanks!
