  • Patent number: 7041241
    Abstract: The invention relates to the use of biodegradable microspheres that release a radiosensitizing anticancer agent for producing a medicament to be used simultaneously with, separately from or spread over time with a radiotherapy, for treating glioblastoma. The use of said biodegradable microspheres according to the invention results in a patient survival time of at least 90 weeks, a therapeutically effective concentration being maintained in the parenchymatous area throughout this time. The microspheres used preferably contain 5-fluorouracile of the tumor, by intratissular injection. The radiotherapy targeting the tumorous mass is dosed at 60 Gy over approximately 6 weeks. The invention also relates to a method for producing the biodegradable microspheres by emulsion-extraction, and to a suspension containing the biodegradable microspheres obtained using this method.

  • Patent number: 6951657
    Abstract: The invention concerns coated particles based on granulated microcrystals of ibuprofen, its pharmaceutically acceptable isomers and salts, characterized in that they comprise a coating obtained in a fluidized bed apparatus with a hydroalcoholic dispersion consisting of a mixture comprising (A) 5 to 50% by weight of ethylcellulose relative to ibuprofen; (B) 10 to 60% by weight of hydroxypeopylmethylcellulose relative to the ethylcellulose; and (C) 1 to 40% by weight of silica with antistatic and permeabilizing properties relative to the ethylcellulose, the resulting coating, whereof at least one of the constituents can be used for granulating the ibuprofen microcrystals resulting in said particles, thereby masking the unpleasant taste of ibuprofen and significantly reducing its irritating effect on the throat after deglutition and substantially immediate release of ibuprofen when the particles are placed in an aqueous medium.
