Aromatase inhibitor are a division of drug that stop the production of oestrogen in woman who are post - menopausal and are used mainly for treating hormone sensory receptor - positive bosom Crab .

What Are Aromatase Inhibitors?

Aromatase inhibitors ( AIs ) , used inhormone therapyor endocrine therapy , are used in treatingbreast cancerinpostmenopausal womenand gynecomastia in men.(1 , 2)Aromatase inhibitors lour the spirit level of estrogen by restricting an enzyme in fat tissue ( aromatase ) from changing other hormones into estrogen .

These drug are broadly occupy for five year once a day to lose weight the risk of breast malignant neoplastic disease .

Aromatase Inhibitor’s Mechanism of Action

Aromatase inhibitor work by inhibiting the natural process of aromatase enzyme , which converts androgen hormones into oestrogen by aromatization . white meat cancer electric cell are fueled by oestrogen . Thus decreasing the yield of estrogen suppresses the return of the breast tumor tissues .

The ovaries in premenopausal women are the main source of estrogen , while in the case of post - menopausal women , most of the estrogen in their bodies is develop in peripheral tissues ( outside the CNS ) , and also a few CNS site in multiple regions within the head .

Breast cancers in premenopausal adult female are normally not treated with aromatase inhibitors , because beforemenopause , the reducing in estrogen hormone activates the hypothalamus and pituitary bloc to increase secernment of gonadotrophin , which can ultimately make the ovary to increase the production of androgen .

In heavy studies , both exemestane and anastrozole drugs have been exhibit to lower the risk of breast cancer in postmenopausal woman who are at increase risk . Although some expert groups include these drugs as options for reduce breast Crab peril in post - menopausal cleaning lady , they are not being approved by the FDA to lower the risk of tit Crab .
