Fulvestrant is a medication used in the treatment of hormone receptor-positive (HR-positive) breast cancer, specifically in postmenopausal women. Fulvestrant is belongs to a class of drugs known as selective estrogen receptor degraders (SERDs). Fulvestrant works by binding to the estrogen receptors on breast cancer cells and then blocking their activity, leading to a degradation of the receptors themselves. This action reduces the growth and proliferation of HR-positive breast cancer cells. Buy high quality Fulvestrant from Molsyns Research.
