ABSTRACT:
A drug targeting system for administering a pharmacologically active substance to the central nervous system of a mammal across the animal's blood brain barrier. The drug targeting system comprises nanoparticles made of poly(DL-lactide) and/or poly(DL-lactide-co-glycolide), a pharmacologically active substance which is absorbed to, adsorbed to, and/or incorporated into the nanoparticles, and either contains TPGS or comprises a pluronic 188 surfactant coating deposited on the drug-loaded nanoparticles.
