  • Fulvestrant nanosphere/microsphere and preparative method and use thereof
    Patent number: 8956659
    Abstract: Fulvestrant nanosphere/microsphere and preparation method and use thereof are provided in the present invention. The carrier material of the fulvestrant nanosphere/microsphere is methoxy ended polyethylene glycol-polylactic acid block copolymer. The nanosphere/microsphere is prepared by solvent-nonsolvent method, in-liquid drying method and/or spray drying method, and has the features of high drug loading and high encapsulation efficiency, controllable release of medicine and no irritant to application site or blood vessel. The fulvestrant nanosphere/microsphere can be used to treat metastatic advanced breast cancer in post-menopausal woman.
