Q

Current recommendation, after 5 years of tamoxifen, give add 5 years of aromatase inhibitors for post-menopausal woman
AE:
1- Increased arthralgia compared to SERMS
2- produce cataracts
4- more diarrhea than tamoxifen

**no good giving this Rx pre-menopausally because most of the estrogen comes from the ovary & giving this can stimulate GnRH release and drive estrogen up further
What are the non-steroidal AIs?
the steroidal?

A

Non-steroidal: Anastrozole, letrozole

steroidal (irreversible): exemestane
