  • Water-soluble polymeric carriers for drug delivery
    Patent number: 5648506
    Abstract: In accordance with the present invention, there are provided polymeric drug delivery systems in which the drug is bound to a water-soluble polymer to provide a form of soluble drug delivery especially for those cases in which the drug by itself is water-insoluble. In particular, the drug taxol is covalently bound to water-soluble polyethylene glycols such as linear polyethylene glycols, branched polyethylene glycols, star polyethylene glycols, and branched copolymers of polyethylene glycols with other functional monomers to comprise a form of polymeric drug delivery. Also, crosslinked insoluble gels of these materials are prepared to serve as a form of implantable drug delivery.
