    摘要: Methods, devices and systems are disclosed for chemically bonding antibiotics to selected substrate materials which are not dissolved in normal physiological processes so that high local concentrations can be achieved during the inflammatory response. The antibiotics will remain permanently bonded to the substrate material until an infection occurs which releases the antibiotic in high concentrations to help control the infection. The high local concentrations may be much higher than systemic toxic levels, and can never reach toxic levels because the local dose is much less than needed to reach systemic toxicity if completely dissolved.

    摘要: A controlled release preparation comprises an ionic polymer matrix loaded with an active compound, particularly a pharmaceutically active compound such as doxorubicin or other cytotoxic or cytostatic drug, the active compound being complexed with a complexing agent such as a metal ion to modify the release of the active compound from the polymer matrix. The ionic polymer matrix may be provided in the form of microspheres, such as microspheres of crosslinked albumin/dextran sulphate.
