摘要:
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.
摘要:
The use of copolymers obtained by free-radical polymerization of a mixture of i) 30 to 80% by weight of N-vinyllactam, ii) 10 to 50% by weight of vinyl acetate, and iii) 10 to 50% by weight of a polyether, with the proviso that the total of components i), ii) and iii) equals 100% by weight, as solubilizers for slightly water-soluble substances.
摘要:
Copolymers for use in solubilizing substances which are insoluble in water, substances which are only sparingly soluble in water, and combinations thereof; such copolymers comprising: (a) 60 to 99% by weight of N-vinylcaprolactam; and (b) 1 to 40% by weight of at least one other monomer selected from the group consisting of: C8-C30-alkyl esters of monoethylenically unsaturated C3-C8-carboxylic acids; N—C8-30 alkyl-substituted amides and N,N—C8-30 dialkyl-substituted amides of acrylic acid, methacrylic acid, or combinations thereof; vinyl esters of aliphatic unbranched C8-C30-carboxylic acids; C8-C30-alkyl vinyl ethers; and mixtures thereof.
