PHARMACEUTICAL COMPOSITIONS OF AMORPHOUS ATORVASTATIN AND PROCESS FOR PREPARING SAME

Solid pharmaceutical compositions containing atorvastatin are disclosed. The compositions include a solid dispersion of amorphous atorvastatin and one or more optional pharmaceutically acceptable excipients. The solid dispersion is prepared by mixing crystalline atorvastatin with a melt-processible polymer and an optional stabilizer and an optional plasticizer at a temperature sufficiently high to soften or melt the polymer and to melt or dissolve the crystalline atorvastatin in the polymer, thereby forming a dispersion of amorphous atorvastatin.
