Seems I may have seen this somewhere on this forum, but I cannot locate it. Can anyone tell me what the difference between Letrozole and anastrozole? They are both AI (aromatase inhibitors) and they both seem to do the same job.
I was thinking that maybe Letrozole was the generic, but then that is what I also thought about anastrozole. I do know that Arimidex is a brand name.
So, can someone set the record straight? Also, is there any difference in effectiveness between them?
