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.

Abstract: Copolymers comprising: (a) 60 to 99% by weight of at least one monomer selected from the group consisting of N-vinyllactams, N-vinylamides, and mixtures thereof; (1) 1 to 40% by weight of at least one monomer selected from the group consisting of vinyl esters of aliphatic branched C8-C30-carboxylic acids; (c) 0 to 30% by weight of vinyl acetate; and (d) 0 to 39% by weight of at least one additional free-radically copolymnerizable monomer; wherein the % by weight content of components (a), (b), (c) and (d) totals 100%, and with the proviso that the total amount of component (b) and component (c) combined is 1 to 40% by weight based on the copolymer, are described along with methods of using such copolymers to solubilize substances which are insoluble in water, substances which are only sparingly soluble in water, and combinations thereof.
