Product Description
Fulvestrant CAS No.129453-61-8 Anti-Cancer Drug Substance
Fulvestrant is a steroidal antiestrogen that is used in the treatment of hormone-receptor positive metastatic breast cancer.
Xi'an Libang Pharmaceutical Co..Ltd developed Fulvestrant API since 2007 and filed the DMF in US FDA in 2009.
Breast cancer
Fulvestrant is used for the treatment of hormone receptor positive metastatic breast cancer or locally advanced unresectable disease in postmenopausal women; it is given by injection.A 2017 Cochrane review found it is as safe and effective as first line or second line endocrine therapy.
It is also used to treat ER-positive, HER2-negative advanced or metastatic breast cancer in combination with palbociclib in women with disease progression after first-line endocrine therapy.
Due to the medication's having a chemical structure similar to that of estrogen, it can interact with immunoassays for blood estradiol concentrations and show falsely elevated results.This can improperly lead to discontinuing the treatment.
