  • Solid Dispersion Comprising Tacrolimus and Entericcoated Macromolecule
    Publication number: 20080132533
    Abstract: This invention relates to a solid dispersion formulation comprising tacrolimus and enteric polymer. The solid dispersion formulation may contribute to better stability of tacrolimus preparation under high temperature and humidity condition through reduced recrystallization rate of tacrolimus. In addition, the solid dispersion formulation releases tacrolimus immediately in aqueous media and elevated solubility level maintains for certain period of time and that way the formulation may also enhance the bioavailability and oral absorption rate of tacrolimus.
