Facile Preparation of Paclitaxel Nano-Suspensions to Treat Lung Cancer

Abstract

Lung cancer is a worldwide issue which account for the death of thousands every year. Paclitaxel (PTX) as the first line chemotherapy drug to treat lung cancer, its clinical applications is largely limited by its poor solubility. The facile preparation of pharmaceutical formulations to increase the solubility as well as targetability of PTX is of vital importance in lung cancer treatment. Herein, we introduced a facile method to prepare PTX nano-suspensions (NSs), which have high drug loading as well as well-dispersed particle size. The in vitro cell experiments revealed its capability to enhance the drug accumulation in A549 cells than free PTX. Moreover, in vivo animal assay suggested its better tumor accumulation and antitumor efficacy than PTX injection (Taxol).
