What is Fulvestrant?

Fulvestrant (Fulvestrant) is an endocrine therapy drug mainly used to treat hormone receptor-positive breast cancer. It belongs to the estrogen receptor antagonist class of drugs, which reduces the impact of estrogen in patients by inhibiting the action of estrogen receptors, thereby slowing or preventing the growth and spread of breast cancer.

In hormone receptor-positive breast cancer, the growth and division of cancer cells are stimulated by estrogen. The mechanism of action of fulvestrant involves two main aspects: first, it reduces the response of cancer cells to estrogen by reducing the number of estrogen receptors; second, it inhibits estrogen receptor signaling, thereby inhibiting the growth and division of cancer cells.

Fulvestrant is usually given as an intramuscular injection, and each course of treatment usually requires two injections. It is used to treat patients with newly diagnosed breast cancer, as well as patients with advanced breast cancer who have already received anti-estrogen therapy. When using fulvestrant, patients need to strictly follow the doctor's instructions and undergo regular clinical monitoring to ensure the efficacy and effectiveness of the drug.
