Description
Fulvestrant is an anti-endocrine compound that exhibits anticancer chemotherapeutic benefit in the treatment of estrogen receptor (ER)-positive breast cancer. Fulvestrant causes degradation of ERs and downregulates ER expression, inhibiting cell growth. Fulvestrant also upregulates expression of UDP glucoronosyltransferase 1A4 (UGT1A4) in cancer cells. Additionally, fulvestrant exhibits some anti-hyperlipidemic benefit in clinical settings, as patients receiving it as a chemotherapeutic also exhibited lower serum levels of total cholesterol and LDL.
