Faslodex (Fulvestrant) Injection

General Information

It gives medication to cancer that has spread to other areas of the body.  This may also be used by patients who have not responded well to other medications.

Breast cancer cells need the hormone estrogen in order to grow.

How does Faslodex (Fulvestrant) Injection work?

Faslodex (Fulvestrant) reversibly and competitively binds to estrogen receptors. It is present in cancer cells. It achieves its anti-estrogen effects through two separate mechanisms.

First, this drug binds to the receptors and regulates them so that estrogen is no longer able to bind to these receptors.

Second, this drug degrades the estrogen receptors to which it is bound. Both of these mechanisms inhibit the growth of tamoxifen-resistant. It also inhibits estrogen-sensitive human breast cancer cell lines.
