Abstract:
Particles having a plurality of crystalline domains are described. Each crystalline domain is oriented differently than any of the adjacent domains and comprises a drug substance. A plurality of interfacial regions surround the crystalline domains, each interfacial region comprising at least one stabilizer. A process used to prepare the particles of the present invention is also described. The particles of the present invention exhibit relatively fast dissolution times as compared to particles prepared by processes described in the prior art.
