Abstract: A formulation comprising a melt-processed solid dispersion product comprising an active agent, a pharmaceutically acceptable thermoplastic polymer of N-vinyl lactams, and a pharmaceutically acceptable polyvinyl alcohol-polyalkylene glycol graft copolymer. A method for producing said formulation.

Abstract: A liquid mixture, comprising a) at least one compound selected from polyols, polyol ethers wherein at least one hydroxyl group is unetherified, or polyalkylene ethers wherein at least one terminal hydroxyl group is unetherified, b) 1,3-bis(caprolactam-1-yl) butane, and c) diacetoxybutane mimics the solubility properties of a graft copolymer comprising a poly(alkylene glycol) backbone and a vinyl acetate/N-vinylcaprolactam copolymer grafted onto the backbone. In a method for evaluating the compatibility of a biologically active substance with the graft copolymer i) the biologically active sub-stance is brought into contact with the liquid mixture, and ii) the phase behavior of the test system and/or the solubility of the biologically active substance in the mixture is determined.

Abstract: The present invention relates to formulations comprising a solid dispersion product of an active agent having at least one of a hydrogen bond donor moiety (e.g. ibuprofen, fenofibric acid or naproxen) and a proton donor moiety and a pharmaceutically acceptable polyvinyllactam polyvinylacetate poly(alkylene glycol) graft copolymer, and to methods for preparing such formulations.

Abstract: An auto-aspirating, rotational dispersion device for gases and liquids with a rotating hollow shaft employed for gas suction and gas channels communicating with said hollow shaft to openings in the gas channels that are positioned at intervals over the circumference of the device, at which openings the gas and liquid are mixed. The device is distinguished by the fact that the gas being dispersed flows in a manner separate from the liquid, from the hollow shaft through the gas channels and is mixed with the liquid outside of the device.
