  • Publication number: 20090318558
    Abstract: The present invention relates to a solvent system with improved disintegration degree and dissolution ratio of a hardly soluble drug by highly concentrating the drug through partial ionization, and by establishing optimal conditions for enhancing bioavailability of the drug, such as the co-relation between the acid drug and the accompanied components, ionization degree of a solvent system, use of an appropriate cation acceptor, water content, selection of optimal mixing ratio of the respective components and use of specific surfactants, and to a pharmaceutical preparation comprising the same. The solvent system of the invention has advantages in that it can enhance bioavailability by improving the disintegration degree and dissolution ratio of a hardly soluble drug and also provide a capsule with a sufficiently small volume to permit easy swallowing.
