    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%.

    摘要: Ion-complexing gels are disclosed for the selective removal of metal ions from plating solutions, the gels comprising hydrophobic nonporous polymers plasticized and swollen with either hydroxyoxime or phosphoric acid ester complexing agents. Also disclosed are novel ion-complexing media comprising polymeric microporous anisotropic beads impregnated with the same complexing agents. Copper, zinc and iron contaminants are effectively removed from nickel-plating solutions.

    摘要: A composition comprises a solid dispersion comprising a low-solubility drug and at least one polymer. At least a major portion of the drug in the dispersion is amorphous. The polymer has a glass transition temperature of at least 100° C. measured at a relative humidity of fifty percent. Another aspect of the invention comprises the same composition except that the dispersion has a glass transition temperature of at least 50° C. at a relative humidity of fifty percent. 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%.
