NANOCRYSTALLINE SOLID DISPERSION COMPOSITIONS AND PROCESS OF PREPARATION THEREOF

摘要

The present invention relates to nanocrystalline solid dispersion compositions having discrete particles, wherein each discrete particle comprises crystals of at least one pharmaceutical active; veterinary active; nutraceutical active dispersed in the matrix of at least one crystallization inducer and/or coexisting with crystals of crystallization inducer, optionally along with pharmaceutically acceptable excipients. The present invention also encompasses a novel one-step process for generation of nanocrystalline solid dispersions. The present invention is particularly of use for improving the dissolution of pharmaceutical actives, veterinary actives; nutraceutical actives exhibiting dissolution-limited bioavailability. Dissolution enhancement is because of the decreased crystallite size of the pharmaceutical active.
