Abstract
Membrane permeability and P-glycoprotein (P-gp) efflux system are regulating factors in the drug brain penetration. Recently, some drug delivery systems have been developed to overcome these limitations. In this study, Metoclopramid has been encapsulated in PLGA nanoparticles using the emulsification/solvent evaporation technique for in-viro evaluation of the effect of PLGA nanoparticles on BBB permeability. Subsequently, prepared nanoparticles were characterized using PCS, TEM, FT-IR, DSC and XRD techniques and in-viro cell permeability of optimum formulation was evaluated using MDCK cell line as BBB model.
