titleOfInvention |
Submicron nanoparticle of poorly water soluble camptothecin derivatives and process for preparation thereof |
abstract |
The present invention relates to a nanoparticle composition comprising a camptothecin derivative, solid polyethyleneglycol and an anti-associative agent, and the process for preparing the same. Specifically, the present invention provides a composition comprising a nanoparticle of the camptothecin derivative, which is prepared by solid-dispersing the poorly water soluble camptothecin derivative in polyethyleneglycol and dissolving the solid dispersions in an aqueous solution containing an anti-associative agent. The composition of the present invention stabilizes the camptothecin derivative lactone form in body fluid for effective anticancer activity. |
