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.
