Fulvestrant, also known as ICI 182,780, and "Faslodex" 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 both by down-regulating and by degrading the estrogen receptor. [S. Kansra, S. Yamagata, L. Sneade, L. Foster & N. Ben-Jonathan, 2005. "Differential effects of estrogen receptor antagonists on pituitary lactotroph proliferation and prolactin release." "Mol Cell Endocrinol." 2005 Jul 15;239(1-2):27-36.] It is administered as a once-monthly injection.

Fulvestrant is marketed by AstraZeneca with the brand name Faslodex.
