Fluvestran is an intramuscular drug developed by AstraZeneca. It was approved by the US Food and Drug Administration in April 2002 and is applicable to the treatment of estrogen receptor positive metastatic breast cancer in postmenopausal women whose disease is still deteriorating after anti estrogen treatment. Many breast cancer cells have estrogen receptors (ER), which can stimulate the growth of such tumors. Fluvastatin is a "pure" estrogen receptor antagonist that does not have a partial estrogenic like agonist effect. It inhibits the estrogen signaling pathway by binding, chemically blocking, and downregulating ER, and can competitively bind with ER. Its affinity with ER is close to that of estrogen, 100 times that of tamoxifen. It is the only antiestrogen drug that can be widely used in clinical practice after tamoxifen's failure. As an endocrine therapy, this drug does not cause common adverse reactions to chemotherapy, so it has good patient compliance. A number of clinical studies have found that the 250 mg dose of fluoxetine has good therapeutic effect and stable safety in the second-line treatment of advanced breast cancer.
