Design, Optimization and in vitro Characterization of Dasatinib loaded PLGA Nano carrier for Targeted cancer therapy: A Preliminary Evaluation

Abstract

Objective: Drug nanoparticles offer a versatile platform for enhancing the dissolution rate and bioavailability of poorly water soluble drugs The present study was aimed to design and develop dasatinib (DAS) loaded Poly lactide co glycolic acid (PLGA) to enhance the dissolution rate and to study the effect of formulation variables for the BCS class II drug dasatinib for the treatment of chronic myeloid leukemia. Methods: The DAS loaded Nps were prepared by using modified double emulsion solvent evaporation method (DESE) using different stabilizers, the formulated Nps were characterized for particle size, zeta potential, Poly Dispersity Index, Surface morphology, Drug entrapment and Invitro drug release. Results: The DAS loaded NP s showed the lowest particles size of 123 nm and zeta potential of – results of Pluronic F68 loaded NP showed the lowest particle size of – and highest zeta potential of --. Surface morphology of NPs with DMAB showed distinct smooth spherical particles with the size range of 50nm. Morphology of Pluronic F68 formulated NPs showed the high degree of aggregation. In vitro drug release showed up to 24hrs in a sustained manner. Conclusion: The result of our study indicates the use of PLGA as a sustained release polymer and using DMAB as a stabilizer for better stable formulation.
