Abstract

A sustained release drug carrier comprises a ceramic composite which is formed by bonding a plurality of ceramic bodies together, and drugs impregnated into the ceramic composite. A method of manufacturing the sustained release drug carrier comprises the steps of: (i) preparing ceramic bodies to be bonded together, each of the ceramic bodies having a bonding surface; (ii) preparing a slurry in which primary particles of a bonding ceramics are dispersed; (iii) applying the slurry to the bonding surface of at least one of the ceramic bodies to be bonded; (iv) sintering the ceramic bodies between which the slurry has been interposed to bond them together, to obtain a ceramic composite; and (v) impregnating a drug into the obtained ceramic composite. According to the structure and method described above, it is possible to provide a sustained release drug carrier whose drug release properties can be controlled and which is capable of exhibiting better drug release action suitable for the application sites, type of drugs to be carried, and the like.
