Exemestane or known by the brand name Aromasin treats breast cancer in postmenopausal women. It is an irreversible steroidal aromatase inhibitor. This tablet works by binding to the active site of the aromatase enzyme which is needed for estrogen production. As a result, it inhibits the synthesis of aromatase and also decreases estrogen formation. These low estrogen levels interfere with the growth and spread of the cancerous cells. Exemestane 25 mg is taken orally. Exemestane tablet price is a little high. However, it can be easily purchased from Magicine Pharma at an affordable price.
