The present study was designed to explore the ability of polymeric nanoparticles to restore drug sensitivity to P-glycoprotein over-expressing cancer cells. A multidrug-resistant cell line 2780 AD and its sensitive parent cell line A2780 were studied in cell culture and as a xenografted tumour model. Paclitaxel was incorporated in poly(lactide-co-glycolide) nanoparticles of average diameter 125 nm...
Purpose This study was carried out to formulate poly(lactide-co-glycolide) (PLGA) nanoparticles using a quaternary ammonium salt didodecyl dimethylammonium bromide (DMAB) and checking their utility to deliver paclitaxel by oral route. Methods Particles were prepared by emulsion solvent diffusion evaporation method. DMAB and particles stabilized with it were evaluated by MTT and LDH cytotoxicity...
