Description
Fulvestrant – Estrogen Receptor Antagonist for Breast Cancer Treatment
Fulvestrant is a prescription hormonal therapy drug classified as a selective estrogen receptor degrader (SERD). It is widely used for the treatment of hormone receptor-positive (HR+), HER2-negative advanced or metastatic breast cancer in postmenopausal women. Fulvestrant works by binding to estrogen receptors, blocking their activity, and accelerating receptor degradation, thereby slowing the growth of estrogen-dependent breast cancer cells.
