Polymeric nanoparticles loaded with Paclitaxel for improved cancer therapy
Fabrication and characterization

Paclitaxel, Soluplus®, Anticancer, Surfactant, NanoparticleAbstract
Paclitaxel (PTX) is well known for its effectiveness in management of cancer. It is associated with solubility problem which is overcome by adding ethanol and Cremophor EL and is available commercially as Taxol. However, Cremophor EL has serious side effects, therefore it is imperative to utilize some other strategies or delivery system for improving its antitumor activity and reduce side effects. The prime objective of this present study was to prepare (Paclitaxel) loaded surface folate decorated and pegylated PLGA (PPF) nanoparticles and characterized for its particle size, polydispersity index, zeta potential, drug loading, drug entrapment efficiency and in vitro drug release. Based upon the in vitro drug release characteristics results the best formulation F4 was selected for observing its surface morphology by SEM and TEM. In vitro release kinetics study unveils that the delivery system follows Korsmeyer-Peppas model suggesting “Fiskian diffusion”.
