Introduction: Brain is supposed to be the most complicated part of the body which is very far from the reach of drug moieties. The drug entry in to the brain region depends upon various factors, and among those, the blood-brain-barrier remains the most prominent one. This barrier restricts the entry of almost all the drug and most of the essential biological components like proteins, peptides, etc. and hinders treatment of the CNS disorders. Alzheimer Disease (AD) is one such brain disorder, more specifically a neurodegenerative disorder which primarily affects the older adults.

Areas covered: From solubility enhancement to targeted delivery, the nanoparticulate system became the answer for almost all the criticality related to drug delivery. Hence, nanoparticulate drug carrier system has been widely utilizing to remove the hurdles of brain drug delivery. Keeping this in mind, we have underlined the proficiencies of the …
