  • 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.

  • Publication number: 20130303628
    Abstract: A curcuminoid formulation, comprising a melt-processed solid dispersion product comprising one or more curcuminoids, a nutritionally acceptable thermoplastic polymer, and a phosphatide; providing an improved oral bioavailability compared to non-formulated crystalline curcuminoid. A method for producing said formulation. A nutritional product fortified with said formulation. Said formulation for use in the treatment or prophylaxis of cancer, conditions involving an inflammatory reaction, neurological disorders, cardiovascular disease, pulmonary disease, the formation of cholesterol gallstones, and parasitic infestation.
