Wirkstoffhaltige Calciumphosphat-Materialien

摘要

The invention relates to calcium phosphate materials containing active ingredients, said active materials being contained in the form of particles (nano- and microencapsulations) which are fixed by ionic interaction in the materials. Said materials are mainly used as layers in implants in human and veterinary medicine or in the form of dispersions, powders, granulates or moulded bodies as bone replacement materials. They enable controlled release of active ingredients from the implant surfaces whereon corresponding layers are placed or from bone replacement material. There is no limitation as to the active ingredients used and the requirements of the surface properties of the substrate material.
