    摘要: A composition comprises a solid dispersion comprising a low-solubility drug and at least one polymer. In another aspect of the invention, a composition comprises a solid dispersion comprising a low-solubility drug and a stabilizing polymer. At least a major portion of the drug in the dispersion is amorphous. The composition also includes a concentration-enhancing polymer that increases the concentration of the drug in a use environment. The stabilizing polymer has a glass transition temperature that is greater than the glass transition temperature of the concentration-enhancing polymer at a relative humidity of 50%.
