Drugs can be delivered to brain with the aid of poly(butylcyanoacrylate) (PBCA) nanoparticles coated with polysorbate 80. These carriers can penetrate BBB and deliver drugs of various structures, including peptides, hydrophilic compounds, and lipophilic compounds eliminated from brain with P-glycoprotein. When a suspension of polysorbate-coated PBCA nanoparticles is introduced into blood, apolipoproteins of the blood plasma adsorb on the particle surface and then interact with receptors of low-density lipoproteins situated in endothelial cells of cerebral vessels, thus stimulating endocytosis. |
