Abstract

Compositions are provided that include having at least 95% by weight of a taxane, or a pharmaceutically acceptable salt thereof, where the particles have a mean bulk density between about 0.050 g/cm3 and about 0.15 g/cm3, and/or a specific surface area (SSA) of at least 18 m2/g, 20 m2/g, 25 m2/g, 30 m2/g, 32 m2/g, 34 m2/g, or 35 m2/g. Methods for making and using such compositions are also provided.
