Abstract: The present invention relates to a tablet composition comprising a particle and a pharmaceutically acceptable carrier, wherein the particle comprises an amorphous structure and a submicron domain, and wherein the amorphous structure is a molecular solid dispersion of a drug in a polymeric matrix and the submicron domain is a submicron drug particle. The tablet may further comprise a micronized drug particle. The pharmaceutically acceptable carrier comprises a binder, a filler, a lubricant, and optionally a gelling agent, a glidant and an anti-sticking agent.

Abstract: 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).

Abstract: The present invention relates to an oral particle composition as an ingredient in an extended-release tablet formulation, comprising a core and a coat, wherein the coat is acid-soluble.

Abstract: The present invention relates to an oral tablet composition for pharmaceutical use, comprising (1) a particle comprising an amorphous structure and a submicron domain and (2) a pharmaceutically acceptable carrier, wherein the composition is optionally coated.
