Title : Preparation of Surface Modified Polymeric Nanoparticles of Doxorubicin

Abstract:

Doxorubicin loaded PLGA nanoparticles were prepared and surface functionalization using trastuzumab, for targeted delivery. Nanoformulations were prepared by double emulsion solvent evaporation method using various stabilizers and size, PDI, zeta potential, entrapment efficiency was evaluated amount of drug loaded into the nanoparticles. The selected nanoformulations were surface functionalized by anti-HER2 antibody trastuzumab and SDS-PAGE analysis was applied to evaluate the activity and stability of antibody after surface modification. In-vitro release profile of selected nanoformulations exhibited biphasic release mechanism with moderate initial burst release followed by sustained release up to ten days. In-vivo pharmacokinetics of doxorubicin nanoparticles in comparison with reference drug ROBOL® in albino mice model exhibited significant increase in C max, AUC, AUMC, MRT and half life and decrease in volume of distribution and clearance was observed in comparison to reference drug. The in-vitro cellular uptake of these nanoformulations was studied usingy breast cancer cell line AU-565 and MCF-7. The results showed the cytotoxicity and IC50 factors were significantly improved in comparison with the control and without surface functionalized doxorubicin loaded PLGA nanoparticles. The prepared surface modified drug delivery system is designed to be administered through intravenous route for the better and improved results.
