| Compound Description | Fulvestrant is a 3-hydroxy steroid that is 17beta-estradiol in which the 7alpha hydrogen has been replaced by a nonyl group in which one of the hydrogens of the terminal methyl has been replaced by a sulfinyl group. An estrogen receptor antagonist, it is used in the treatment of breast cancer. It has a role as an antineoplastic agent, an estrogen receptor antagonist and an estrogen antagonist. It is a 3-hydroxy steroid, a 17beta-hydroxy steroid, an organofluorine compound and a sulfoxide. It derives from a hydride of an estrane.Fulvestrant is a drug treatment of hormone receptor -positive metastatic breast cancer in post-menopausal 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. While it is used as monotherapy for the treatment of breast cancers, it is also used in combination with [alpelisib] for the treatment of HR-positive, human epidermal growth factor receptor 2 -negative, PIK3CA-mutated, advanced or metastatic breast cancerFulvestrant is an Estrogen Receptor Antagonist. The mechanism of action of fulvestrant is as an Estrogen Receptor Antagonist, and Selective Estrogen Receptor Modulator.Fulvestrant is a steroidal antiestrogen that is used in the treatment of hormone-receptor positive metastatic breast cancer. Fulvestrant therapy can be associated with serum enzyme elevations, but has yet to be linked to instances of clinically apparent acute liver injury in the published literature.Fulvestrant is a synthetic estrogen receptor antagonist. Unlike tamoxifen and the aromatase inhibitors , fulvestrant binds competitively to estrogen receptors in breast cancer cells, resulting in estrogen receptor deformation and decreased estrogen binding. In vitro studies indicate that fulvestrant reversibly inhibits the growth of tamoxifen-resistant, estrogen-sensitive, human breast cancer cell lines. FULVESTRANT is a small molecule drug with a maximum clinical trial phase of IV that was first approved in 2002 and has 6 approved and 30 investigational indications.An estradiol derivative and estrogen receptor antagonist that is used for the treatment of estrogen receptor-positive, locally advanced or metastatic breast cancer. |
