Paclitaxel dosage form on nanoparticles of 200-300 nm based on lactic and glycolic acid copolymer was obtained by the co-precipitation method. The possibility of controlled release of paclitaxel at pH 7.4 for 24 h was studied in vitro. Studies on Jurkat/WT human T-lymphoblastic leukemia cells showed that incorporation of paclitaxel in the nanoparticles led to a 4-fold increase of its cytotoxicity (6.8∈×∈10 -6 M) in comparison with paclitaxel solution. The efficiency of compositions containing polysorbate-80 was comparable to that of non-modified nanoparticles containing paclitaxel. © 2011 Springer Science+Business Media, Inc. Source
