Menopausal symptoms
OP
MSK Pain

71

Anastrazole stops peripheral conversion of androgens to oestrogens however in younger women, production is largely by the ovaries

Q

What is the MOA of Tamoxifen?

A

SERM thus blocks oestrogen receptors in breast tissue and stimulates oestrogen receptors in uterus and bone - prevents OP but increases risk of endometrial cancer

Q

What is the MOA of Anastrazole?

A

Anastrozole is an Aromatase inhibitor which reduces the peripheral conversion of testosterone to oestrogens.

Used in postmenopausal women
