摘要：

The present invention relates to compositions and methods of the preparation of an oral particle essentially consisting of an amorphous structure and a submicron domain, wherein both amorphous structure and submicron domain comprise a drug, and wherein the particle shows crystalline property. The desired ratio of the amorphous structure to the submicron domain is between 0.1:5 and 1:1. And, the desired average particle diameter is between mesh 12 (1680 microns) and mesh 100 (149 microns).
