Abstract:
The invention relates to the use of copolymers which comprise a) 60 to 99 % by weight of N-vinylcaprolactam; b) 1 to 40 % by weight of at least one monomer b) selected from the group including: b1) C8-C30 alkyl esters of monoethylenically unsaturated C3-C8 carboxylic acids; b2) N-alkyl- or N,N-dialkyl-substituted amides of the acrylic acid or the methacrylic acid with C8 to C30 alkyl groups; b3) the vinyl esters of aliphatically unbranched C8-C30 carboxylic acids; b4) the C8-C30 alkyl-vinyl ethers, as solubilizers for substances that are difficult to dissolve in water.
Abstract:
The invention relates to the use of copolymers obtained by radically polymerising a mixture of i) 30-80 % by weight N-vinyllactam, ii) 10-50 % by weight vinylacetate, and iii) 10-50 % by weight polyether, wherein the sum of the components i), ii) and iii) is equal to 100 % by weight as solubilisers for poorly water-soluble substances.
Abstract:
The invention relates to the use of polyvinyl lactame-polyalkylene oxide block copolymers as solubilisers for poorly water-soluble substances.

Abstract:
A directly tabletable ibuprofen formulation comprising a) 50-99% by weight of crystalline ibuprofen, b) 1-15% by weight of a finely divided excipient with a surface area of at least 100 m2/g, and c) 0-40% by weight of further excipients, with the proviso that the total amount of components a) to c) corresponds to 100% by weight, where at least 50% of the surface of the ibuprofen crystals are covered with the finely divided excipient.
