Abstract

See full text

The present invention is directed to a particulate pharmaceutical composition. The particulate pharmaceutical composition can comprise a water-soluble or partially water-soluble polymer matrix; and a plurality of nano-sized particles of active agent which are sparingly water-soluble to water-insoluble dispersed in the water-soluble or partially water-soluble polymer matrix. The particulate pharmaceutical composition can be micronized or in the form of a film that can be rolled up. If micronized, the individual micron-sized particles can have a plurality of nano-sized particles present in the micron-sized particles.
