ABSTRACT:
This invention relates to pharmacologically-active polymeric compounds; to substrates, such as implantable medical devices formed thereof or coated therewith; and to methods of using said compounds or said substrates for providing pharmacological agents released in response to in vivo activation at a desired location in a mammal. The polymeric material has a backbone comprising a pharmacologically-active fragment covalently linked through at least two functional groups within the backbone, wherein the backbone comprises, preferably, polyamide, polyurethane and/or polyurea linkages with, optionally, polyester, polycarbonate, polyether and/or polyvinyl linkages. The preferred pharmacological compounds are fluoroquinolines, particularly, ciprofloxacin. The pharmacologically-active compounds provide in vivo enhanced long term anti-inflammatory, anti-bacterial, anti-microbial and/or anti-fungal activity.
