Intranasal drug delivery: A non-invasive method for improving neurotherapeutic delivery

New nanotechnology tactics to enhance drug delivery to the central nervous system have drawn increasing attention from academics and drug designers in recent years (CNS). The treatment of neurological conditions, including Alzheimer's disease, Parkinson's disease, brain tumours, and stroke, has a significant deal of potential to be impacted by nanotechnology. Numerous investigations on the topic of neurodegeneration revealed that CNS illnesses have been successfully treated with nanomaterials. Nanocarriers have made it possible to transport chemotherapeutics to specific locations, which has effectively slowed the growth of malignant brain tumours. The treatment of CNS diseases, which improves the overall effect of medication and emphasises the significance of nano-therapeutics, is thus the most effective application of nanomaterials. In order to transport therapeutic agents to the CNS, this study was done to analyse the data on the use of nanotechnology in the design of drug delivery systems that can pass through the blood-brain barrier (BBB).
