  • Publication number: 20080112918
    Abstract: A method for treating gout and/or reducing serum uric acid levels in a patient is disclosed that includes administering to the patient a therapeutically effective amount of an amine polymer, for example, an aliphatic amine polymer. In one embodiment, the polymer binds to uric acid or a precursor thereof. Examples of polymers useful in an embodiment of the invention include sevelamer hydrochloride and colesevelam. The invention includes the use of amine polymers such as a cross-linked polymer characterized by a repeat unit having the formula: and salts and copolymers thereof, where n is a positive integer and x is zero or an integer between 1 and about 4. Also described is a use, for the manufacture of a medicament, of a polymer that binds serum uric acid in a patient.

  • Patent number: 7261880
    Abstract: The invention relates to a method for treating Syndrome X, or inhibiting the onset of symptoms of Syndrome X in a patient, and includes administering a therapeutically effective amount of a salt of at least one alkylated and cross-linked polymer, or a copolymer thereof, the polymer salt formed as a product of the reaction of one or more polymers, or salts and copolymers thereof, having a repeat unit that is essentially: where n is a positive integer and each R, independently, is H or a C1–C8 alkyl group; at least one aliphatic alkylating agent; and a cross-linking agent. Long term administration of the cross-linked polyamine salts of the invention increases HDL levels and decreases LDL levels in patients. The invention also provides for administration of the polymer salt colesevelam, in combination with an HMG-CoA reductase inhibitor; the combined administration is effective in further lowering serum total-cholesterol and LDL-cholesterol levels beyond that achieved by either agent alone.
