Fulvestrant Description:

Fulvestrant (Faslodex, AstraZeneca) is a drug treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following anti-estrogen therapy. It is an estrogen receptor antagonist with no agonist effects, which works by down-regulating the estrogen receptor.
 
Fulvestrant is a selective estrogen receptor down-regulator (SERD). Fulvestrant is indicated for the treatment of hormone receptor positive metastatic breast cancer in postmenopausal women with disease progression following anti-estrogen therapy. The dosing schedule for fulvestrant remains under investigation in an attempt to optimize its effectiveness.
 
Fulvestrant provided effective second-line therapy in this setting for postmenopausal women who had relapsed or progressed after previous endocrine therapy.

Fulvestrant Applications :

Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive. Drugs that block the effects of these hormones can slow or stop the growth of the breast cancer cells. Fulvestrant stops oestrogen getting to the cancer cells by blocking oestrogen receptors and reducing the number of receptors the cancer cell has.
