Nanotherapeutics in Neuropathologies: Obstacles, Challenges and Recent Advancements in CNS Targeted Drug Delivery Systems

Neurology and associated nanotherapeutics are a complex field in terms of therapeutics and neurological disorder complexity. The brain is an intricate appendage and requires more precise embattled treatment for the particular diseases and hence it is a broad scale for developing more targeted drug deliveries. The brain is one of the most inaccessible tissues of the body due to the existence of the blood-brain barrier (BBB), thus delivery of drugs inside the brain is a striking dare and it is also tricky to treat central nervous system (CNS) complications pharmacologically. The therapeutic aspiration is to accomplish the lowest drug meditation in the brain tissues so as to gain favoured therapeutic results. To devastate this obstacle, nanotechnology is engaged in the field of targeted brain drug delivery and neuropathology targeting. These carriers hold myriad abilities as they may augment the drug delivery into the brain by shielding them from degradation and prolonging their transmission in the blood, as well as promoting their transport through the BBB. Nanopharmaceuticals are quickly sprouting as a new avenue that is engaged with the drug-loaded nanocarriers to demonstrate unique physicochemical properties and tiny size range for penetrating the central nervous system. The enchantment behind their therapeutic achievement is the condensed drug dose and inferior toxicity, whereby restricting the therapeutic compound to the specific site. Therefore, in this article, we have tried to recapitulate the advances of the novel scopes for the brain targeted drug delivery for complex neurological disorders.
