  • Pharmaceutical compositions of dispersions of amorphous drugs mixed with polymers
    Patent number: 8703196
    Abstract: A pharmaceutical composition comprises a dispersion comprising a low-solubility drug and a matrix combined with a concentration-enhancing polymer. At least a major portion of the drug is amorphous in the dispersion. The compositions improve the stability of the drug in the dispersion, and/or the concentration of drug in a use environment.
    Type: Grant
