  • Patent number: 10653625
    Abstract: A method is described for the production of dosage forms, which comprise a solid dispersion of a microcrystalline active substance, in which a thermoplastic polymer with a glass transition temperature Tg of at least 40° C. is melted and an active substance is dissolved homogeneously in the melt; crystallization of the active substance is initiated in the mass obtained; and the mass is cooled. Crystallization of the active substance can be initiated by adding a nonsolvent, seed crystals of the active substance or a derivatization reagent. In addition, crystallization can be initiated by holding the mass for a sufficient length of time at a temperature that is below the temperature at which the active substance is completely soluble in the mass.

  • Patent number: 9402909
    Abstract: A pharmaceutical dosage form comprises a solid dispersion product of at least one active ingredient dispersed in a polymeric binder composition, the polymeric carrier composition comprising a) a vinylpyrrolidone homopolymer, wherein at least 95% by weight of the vinylpyrrolidone homopolymer has a molecular weight distribution within the range of from 1000 to 13 000; and b) a vinylpyrrolidone copolymer having a weight-average molecular weight of from 5000 to 1 500 000. The dosage form is preferably prepared by a melt extrusion process. The polymeric carrier composition exhibits a high drug dissolution power and allows a reduction of the viscosity of the melt without deteriorating the mechanical properties and storage stability of the dosage form.

  • Patent number: 9149431
    Abstract: A solid dispersion product comprising itraconazole and hydroxypropyl methylcellulose, which satisfies the Formula 0.35>?Htr (1) (wherein ?Htr represents the endotherm (J/g) accompanying a transition at about 240° C.). The solid dispersion product shows an improved bioavailability.
