    Abstract:
    Neurocysticercosis is a neglected tropical disease that affects the central nervous system and is the most common cause of human epilepsy acquired in developing countries. Therapeutic failures attributed to medical management of neurocysticercosis with albendazole (ABZ) have been primarily linked to the poor drug absorption rate resulting in low drug level in plasma and brain tissue. The aim of the current work was to characterize and compare the brain pharmacokinetic behavior of ABZ formulated as a suspension or lipid nanocapsules (ABZ-LNCs) in healthy mice. The relative availability in brain tissue of the active metabolite ABZ sulphoxide increased 183% when ABZ was administered as LNCs, in relation to ABZ suspension. The parent drug was also detected for a short period of time. The bioavailability of ABZ in ABZ-LNCs treated mice increased more than 2 fold compared with ABZ suspension group. The enhanced drug brain exposure observed after administration of ABZ-LNCs to healthy mice has potential usefulness for the treatment of human neurocysticercosis.
