Many of the therapeutics used for the treatment of brain disorders are not effective and not delivered to the brain due to the complex structure and its barriers. In recent years, many advanced approaches have emerged for the brain drug delivery. Intranasal drug delivery is one of non-invasive approach has gained interest because of direct transport of drugs circumventing the brain barriers through olfactory and trigeminal nerve pathways. Even though through these pathways the therapeutics have direct access to the brain, the main limitations of this approach are only limited drug absorption, and nasal permeability
