  • Patent number: 8940800
    Abstract: Disclosed are polymers of hydroxypropyl methyl cellulose acetate succinate (HPMCAS) and hydroxypropyl methyl cellulose acetate (HPMCA) with unique degrees of substitution of hydroxypropoxy, methoxy, acetyl, and succinoyl groups. When used in making compositions comprising a low-solubility drug and such polymers, the polymers provide enhanced aqueous concentrations and/or improved physical stability.

  • Patent number: 8883209
    Abstract: 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%.
