Faslodex (Fulvestrant) is an anti-estrogen medication. It works by blocking the actions of estrogen in the body. Certain types of breast cancer use estrogen to grow and multiply in the body.
Faslodex (Fulvestrant) is used to treat a certain type of hormone-related breast cancer in postmenopausal women, when the cancer has spread to other parts of the body after treatment with anti-estrogen medication.
Faslodex (Fulvestrant) is also used together with a medicine called palbociclib, to treat certain hormone-related breast cancer that has progressed or spread after treatment with hormonal therapy.
Mechanism of action:
Faslodex (Fulvestrant) competitively and reversibly binds to estrogen receptors present in cancer cells and achieves its anti-estrogen effects through two separate mechanisms. First, Faslodex (Fulvestrant) binds to the receptors and downregulates them so that estrogen is no longer able to bind to these receptors. Second, Faslodex (Fulvestrant) degrades the estrogen receptors to which it is bound. Both of these mechanisms inhibit the growth of tamoxifen-resistant as well as estrogen-sensitive human breast cancer cell lines.
