PHARMACEUTICAL PREPARATION FOR DELIVERING RIFAMYCIN DERIVATIVE TO DAMAGED TISSUE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a pharmaceutical preparation delivering a rifamycin derivative specifically to a damaged site. <P>SOLUTION: The pharmaceutical preparation is obtained by sealing a rifamycin derivative-containing composition in a microparticle or nanoparticle, and the rifamycin derivative-containing composition is selectively delivered to damaged tissue compared to normal tissue. As a result, the enhancement of the effect of the rifamycin derivative at the damaged tissue and the reduction or inhibition of side effects in normal tissue are expected. <P>COPYRIGHT: (C)2009,JPO&INPIT |
