Estimating the term…
This invention relates to biotechnology, more particularly, to water-soluble polymeric delivery systems for the imaging, evaluation and/or treatment of rheumatoid arthritis and other inflammatory diseases. Using modern MR imaging techniques, the specific accumulation of macromolecules in arthritic joints in adjuvant-induced arthritis in rats is demonstrated. The strong correlation between the uptake and retention of the MR contrast agent labeled polymer with histopathological features of inflammation and local tissue damage demonstrates the practical applications of the macromolecular delivery system of the invention.
A pharmaceutical composition for the treatment of an inflammatory disease, comprising a N-(2-hydroxypropyl) methacrylamide copolymer and a physiologically acceptable carrier, wherein said N-(2-hydroxypropyl)methacrylamide copolymer consists of N-(2-hydroxypropyl)methacrylamide and N-methacryloyl glycylglycyl hydrazone glucocorticoid or a pharmaceutically acceptable salt thereof, and wherein said glucocorticoid is dexamethasone.
