METHOD FOR TREATING WARM-BLOODED VERTEBRATES WITH HALIDE-FREE GLUCOSAMINE-ACIDIC DRUG COMPLEXES

摘要

The invention provides a method of treating a warm-blooded vertebrate. The vertabrate 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.
