  • Patent number: 8338341
    Abstract: The invention provides a process for the production of a granule of a coated oxidizing compound which granule has good delayed release properties, said process comprising a) providing cores of an oxidizing compound produced by fluidized bed spray granulation, b) spraying on the oxidizing compound cores an aqueous solution of metal sili-cate in a fluidized bed, said aqueous solution comprising at least 15% by weight metal silicate, and c) drying to form a metal silicate coating layer on the oxidizing compound core, provided that the amount of metal silicate coating layer is at least 8%, preferably at least 10% by weight based on the total weight of the granule. The invention also provides such granule and well treatment fluids including such granule, and processes for use.

  • Patent number: 6673819
    Abstract: The present invention relates to novel compounds of Formula I, and pharmaceutically acceptable salts thereof, as antibacterial agents. The compounds of the present invention are nitric oxide releasing derivatives of proton pump inhibitors (NO-releasing PPIs). In further aspects, the invention relates to compounds of the invention for use in therapy; to processes for preparation of such new compounds; to pharmaceutical compositions containing at least one compound of the invention, or a pharmaceutically acceptable salt thereof, as active ingredient; and to the use of the active compounds in the manufacture of medicaments for the medical use indicated above. The invention also relates to new intermediates for use in the preparation of the novel compounds. Additionally the present invention relates to co-administration of NO-releasing PPIs with other known medicaments.

  • Patent number: 5556855
    Abstract: A compound of the formula Het--NR--SO.sub.2 --Ph.sup.2 --A--Ph.sup.1 (COOH)(OH) and tautomic form, salts, solvates, C.sub.1-6 alkyl esters and pharmaceutical compositions of the compound. Ph.sup.1 and Ph.sup.2 are benzene rings with the proviso that carboxy and hydroxy are ortho to one another. Het includes an optionally substituted heterocyclic ring which includes conjugated double bonds and binds to nitrogen in NR. The compound is characterized in that A is a bridge which is stable against reduction because it is not azo, and in that R is hydrogen or lower alkyl.The invention also includes the preparation of the compound and its use as a drug, particularly for treating autoimmune diseases.
