摘要:
The present invention provided nanocrystals of fluticasone propionate having an X-ray powder diffraction pattern including peaks at about 7.8, 15.7, 20.8, 23.7, 24.5, and 32.5 degrees 2θ further including peaks at about 9.9, 13.0, 14.6, 16.0, 16.9, 18.1, and 34.3 degrees 2θ, characterized in that :the nanocrystals are nanoplates having the [001] crystallographic axis substantially normal to the surfaces that define the thickness of the nanoplates,wherein said nanoplates have an average size between 100 and 1000 nm.
