  • Patent number: 11116728
    Abstract: A pharmaceutical composition comprises multiparticulates comprising a melt-congeal core and a solid amorphous dispersion layer of a poorly water soluble drug and polymer. The multiparticulates are suitable for improving bioavailability of poorly water soluble drugs. The melt-congeal cores facilitate application of the solid amorphous dispersion layer, and allow incorporation of additional optional components to the core so as to adjust the release of drug from the multiparticulate.

  • Patent number: 9713594
    Abstract: An exemplary method comprises providing a spray-dried dispersion comprising particles, the particles comprising an active agent and a polymer, the dispersion particles having an average particle diameter of less than 50 ?m. An ordered mixture is formed by high-shear mixing the dispersion with a powdered glidant, wherein the average particle diameter of the glidant is less than or equal to one fifth the average particle diameter of the dispersion after high-shear mixing. The dosage forms are formed by at least one of directly compressing the ordered mixture to form a tablet and encapsulating the ordered mixture to form a capsule.
