Overview Of Femistra 1mg Tablet

Femistra 1mg tablets is a hormone therapy medication that is used to treat breast cancer in postmenopausal women. Anastrozole is the generic name of this medication and it is a competitive non-steroidal aromatase inhibitor. This medication is strictly prescription-based.


In many breast cancers, estrogen stimulates the uncontrollable growth of cancerous cells. Aromatase enzyme present mainly in the adrenal glands can convert the androgens to estrogen and this estrogen furthermore influences the cancerous cells. Thus, Femistra is a non-steroidal inhibitor that competitively binds to the aromatase enzyme and stops the production of estrogen. As a result, it inhibits the growth and spreading of the tumor cells.
