Concerned about the side effects of anastrozole

Looked online, and it appears that exemestane IS an off patent drug. The brand name product is called Aromasin. I do not understand why it is still so expensive, unless is more effective or has fewer side effects than the other two Aromatase Inhibitors. I don’t understand all this, but I think it does have a different chemical reaction in the body than Arimidex or Femara.

I'll ask my Oncologist when I speak to her next time. Thank you for your follow-up!

@cfacarol
Although Exemestane (Aromasin) is an AI and functions like anastrozole and letrozole, it is chemically different in that it is a steroid. It may be that difference which allows manufacturers to charge more? and insurance companies to try to steer patients away from it?
