Fulvestrant is a muscle injection drug and is suitable for treating postmenopausal women with estrogen receptor-positive metastasized breast cancer whose condition continued to worsen despite antiestrogen treatment. Fulvestrant is the only antiestrogen drug that can be widely clinically used following unsuccessful tamoxifen treatment. This drug is a type of endocrine therapy, so it will not cause any adverse effects commonly seen in chemotherapy, giving it relatively good patient compliance. Multiple clinical trials have found that 250mg Fulvestrant is effective and consistently safe as a second line of treatment for advanced breast cancer.
