Slightly off-topic, but could you talk about what pharmacy benefits managers are supposed to do and actually do, for insulin especially, and their effect on the market?

I Googled this term but can't make of sense of your comment based on what I've read. (The definitions of pharmacy benefits managers that I found have nothing to do with what you wrote.)

There is a paragraph in the wikipedia article on PBM[0] full of sources on this.
