Title:
骨補填剤,放出制御担体,及びそれらの製造方法
Document Type and Number:
Japanese Patent JP5405119
Kind Code:
B2
Abstract:
A bone filling material having controlled release of a pharmaceutical agent such as a growth factor, and a drug release controlling carrier having controlled release of a pharmaceutical agent is provided by inactivating a functional group which can strongly bind to the pharmaceutical agent of the bone filling material with a blocking agent. The bone filling material and the drug release controlling carrier of the present invention comprises: a calcium-based material such as hydroxyapatite, carbonate apatite, fluorapatite, chlorapatite, ²-TCP, and ±-TCP; a blocking agent of the calcium-based material such as serine and dextran; and a pharmaceutical agent.
