  • Patent number: 7662803
    Abstract: A method of treating a warm-blood vertebrate. The vertebrate may be a human being or a lower animal. The treatment method involves administering to the vertebrate in need of such treatment a pharmaceutically effective amount of a complex of halide-free glucosamine and a therapeutic drug having a pKa of less than 7. Preferably, the complex is stabilized by coating it with at least one pharmaceutically acceptable polymer comprising a water-soluble, water-immiscible and/or water-swellable homopolymer and/or copolymer. Suitable polymers include carboxypolymethylene homopolymers and copolymers; polyethylene glycol homopolymers and copolymers, povidone homopolymers and copolymers, polyacrylic acid homopolymers and copolymers; polyacrylamide homopolymers and copolymers; polysaccharides; and mixtures of two or more of the foregoing polymers. The resultant polymer-coated complex will be stable upon exposure to ambient temperature and/or the atmosphere.

  • Publication number: 20070248677
    Abstract: A method of treating a warm-blood vertebrate. The verebrate may be a human being or a lower animal. The treatment method involves administering to the vertebrate in need of such treatment a pharmaceutically effective amount of a salt of a halide-free glucosamine base and a therapeutic drug containing at least one acid functionality, e.g., a carbonyl moiety, a carboxyl moiety, a sulfoxide moiety, etc. Preferably, the salt is stabilized by coating it with at least one pharmaceutically acceptable polymer comprising a water-soluble, water-immiscible and/or water-swellable homopolymer and/or copolymer. Suitable polymers include carboxypolymethylene homopolymers and copolymers; polyethylene glycol homopolymers and copolymers, povidone homopolymers and copolymers; polyacrylic acid homopolymers and copolymers; polyacrylamide homopolymers and copolymers; polysaccharides; and mixtures of two or more of the foregoing polymers.

  • Patent number: 6900189
    Abstract: This invention relates to a composition comprising a glucosamine material and an analgesic compound such as a nonsteroidal anti-inflammatory drug (NSAID) and/or an opioid analgesic and its use for treatment of pain in pharmaceutical or veterinary applications. When the components of the compositions are administered within certain ratios, the analgesic efficacy of the composition is super-additive (synergistic) relative to the analgesic efficacy of the analgesic compound alone.
