Abstract:
Described is a storage-stable dust-free homogeneous particulate formulation. The formulation consists of (a) at least one water-soluble Vitamin E-derivative, (b) at least one hydrophilic polymer, (c) optionally additional surface-active substances, and (d) optionally additional pharmaceutical additives. The sum of (a), (b), (c) and (d) equals 100% by weight of the formulation. The fines fraction with particle diameters of less than 100 μm is less than 10% by weight. Describe also is a process for manufacturing the formulation, and use of the formulation as a solubilizing composition in pharmaceutical formulations.
Abstract:
Dosage forms comprising preparations of slightly water-soluble active substances in a polymer matrix of polyether copolymers, the polyether copolymers being obtained by free radical polymerization of a mixture of from 30 to 80% by weight of N-vinyllactam, from 10 to 50% by weight of vinyl acetate and from 10 to 50% by weight of a polyether, and of at least one slightly water-soluble polymer in which the slightly water-soluble active substance is present in amorphous form in the polymer matrix.

Abstract:
The use of water-soluble or water-dispersible copolymers which are obtained by free radical-initiated polymerization of a mixture of i) 30 to 80% by weight N-vinyllactam, ii) 10 to 50% by weight vinylacetate and iii) 10 to 50% by weight of a polyether, with the proviso that the total of i), ii) and iii) is equal to 100% by weight, as binders for producing solid active ingredient-containing dosage forms.
Abstract:
Method for producing pigment-containing granules for pharmaceutical applications based on film-forming enteric polymers, wherein the production of the granules takes place by a spraying process in which the enteric polymeric film formers are introduced as initial charge in a fluidized bed, and an aqueous pigment suspension, which comprises a plasticizer that is solid at 20° C., is sprayed onto the fluidized bed.
Abstract:
The present invention relates to a powder mixture for the preparation of a granulate comprising as constituent at least a filler or at least an active ingredient or both and as granulation aid Magnesium diacetate×4H2O and/or Magnesium dichloride×6H2O and/or Magnesium sulfate×7H2O and/or Disodium sulfate xH2O and/or Sodium thiosulfate×5H2O and/or Na3PO4×12H2O and/or Na2HPO4×12H2O/7H2O and/or Sodium acetate×3H2O. Optionally constituents of the powder mixture to be granulated are binders, disintegrants and further customary auxiliaries. It was an object of the present invention to provide a powder mixture which can be granulated without adding a liquid but where the water for the granulation is released in-situ from Magnesium diacetate×4H2O and/or Magnesium dichloride×6H2O and/or Magnesium sulfate×7H2O and/or Disodium sulfate xH2O and/or Sodium thiosulfate×5H2O and/or Na3PO4×12H2O and/or Na2HPO4×12H2O/7H2O and/or Sodium acetate×3H2O. An additional drying step is not required.
Abstract:
The present invention relates to a direct tableting auxiliary composition based on lactose powder mixed intimately with a water-soluble polyethylene glycol-polyvinyl alcohol graft copolymeras binder, crosslinked insoluble polyvinylpyrrolidone as tablet disintegrating agent and a lubricant.
Abstract:
An odorant and flavoring formulation for topical application comprising, as matrix former, a mixture of at least one water-insoluble polymer from the group of homo- or co-polymers of C1-C4-carboxylic acid vinyl esters and at least one water-soluble polymer from the group of homo- or copolymers of N-vinyllactams.
Abstract:
A storage-stable dust-free homogeneous particulate formulation comprising at least one water-soluble Vitamin E-derivative and at least one hydrophilic polymer. In one embodiment the storage-stable dust-free homogeneous particle formulation, consists of (j) at least one water-soluble Vitamin E-derivative, (k) at least one hydrophilic polymer, (l) optionally additional surface-active substances, and (m) optionally additional pharmaceutical additives, with the proviso, that the sum of (a), (b), (c) and (d) equals 100% by weight of the formulation, and wherein the fines fraction with particle diameters of less than 100 μm is less than 10% by weight. Methods of making the particulate formulation by a spray granulation process are also provided.
