Product Description
Fulvestrant Anti-Cancer Drug Substance
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.
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.
