点では必ずしも十分とは言えない。[Problems to be Solved by the Invention] However, since the polymer used hardly decomposes in vivo, it is necessary to gradually remove it as bone tissue is repaired. Therefore, an implant that does not need to be taken out after surgery and that can supplement bone tissue repair by containing artificial bone components such as hydroxyapatite and β-tricalcium phosphate is desired in the field of bone and joint infections. ing. Such an implant is described in J. Controlled Release V, Journal of Controlled Releases, Vol. 2, pp. 179-186, 1985.
ol. 2 179-186 (1985)), dibekacin and hydroxyapatite are dispersed and solidified in polylactic acid. However, the release of dibekacin from the implant exhibited a relatively high initial release behavior. To prepare implants that do not need to be taken out after surgery, it is suitable to use biodegradable polymers such as polylactic acid as described above, but this is not always sufficient in terms of controlling the drug release rate. I can't say that.

This is a drug-containing preparation for implantation into bone, which is characterized by using a molded product. Furthermore, the present invention is characterized in that the drug and the polymeric substance are mixed and compressed or melted and solidified to form a molded product, which is then crushed into granules, and then an artificial bone component is mixed and further compression molded. This is a method for producing a preparation for implantation into bone containing a drug.

A formulated preparation for implantation into bone can be obtained. Therefore, an object of the present invention is to provide a preparation for implantation into bone containing a novel drug with a controlled drug release rate. Any drug can be used in the present invention as long as it needs to be implanted inside the bone. Antibiotics are usually used, but drugs such as anticancer agents can also be used if necessary.
