Abstract
A fulvestrant pharmaceutical composition, a preparation method therefor, and an application thereof are provided. The fulvestrant pharmaceutical composition contains fulvestrant solid particles. The particle size of the fulvestrant solid particles satisfies that Dv(10) is selected from 0.400 micrometers to 6.000 micrometers, Dv(50) is selected from 0.700 micrometers to 6.000 micrometers, and Dv(90) is selected from 1.000 micrometers to 6.000 micrometers, provided that Dv(10) is not 0.400 micrometers, Dv(50) is not 0.700 micrometers, and Dv(90) is not 1.000 micrometers. The fulvestrant pharmaceutical composition has a long-acting sustained release.
