The present invention relates to oxaliplatin nanoparticles, oxaliplatin being a water-soluble active substance, to a pharmaceutical composition comprising the nanoparticles, and to a method which involves emulsifying a lipid mixture solution, in which solid lipids and a surfactant are mixed, into an aqueous mixture solution in which oxaliplatin and a specific cosolvent are mixed, and removing the solid lipids and the cosolvent using supercritical fluid gas, to thereby prepare orally administrable nanoscale oxaliplatin particles. The oxaliplatin nanoparticles and method for preparing same according to the present invention are advantageous in that oxaliplatin nanoparticles, oxaliplatin being a water-soluble active substance, can be prepared in an economic manner using a supercritical fluid production facility which is relatively inexpensive, and oxaliplatin nanoparticles can be prepared with a high recovery factor through a simple process and can be easily commercialized. In addition, oxaliplatin, which has been thus-far prepared as injectable formulations, is prepared into nanoparticles to enable the development of oxaliplatin oral formulations which are safe to stomach acids and which have improved bioavailability, thereby preventing inconveniences and problems in using injectable formulations, and significantly contributing to the improvement of patient compliance and a reduction in medical expenses. |
