Unravelling Micro and Nano vesicular System in Intranasal Drug Delivery for Epilepsy.

Epilepsy is one of the major neurological disorders, affecting about 50 million people globally. Oral, intravenous, and rectal delivery systems are available for the management of epileptic seizures. However, intranasal delivery serves beneficial for delivering anti-epileptic drugs owing to the advantages it offers. Various approaches have been developed over the years aiming to attain either a safer or faster brain delivery; a nasal delivery system proposes significant outcomes. The non-invasiveness and high vascularity contribute to the high permeability of the nasal mucosa, allowing rapid drug absorption. This review highlights some of the promising novel approaches delivering antiepileptic drugs efficiently employing the nasal route. The method includes a collection of data from different search engines like PubMed, ScienceDirect, SciFinder for obtaining appropriate and relevant literature regarding epilepsy, intranasal delivery of antiepileptic agents, and novel therapeutics. The present review underlines the majority of work related to intranasal delivery in the treatment of epilepsy, aiming to draw the attention of the researchers towards the easiest and efficient ways of formulation for the delivery of antiepileptics during seizures. This review intends to provide understanding about the delivery aspects of anti-epileptic drugs, the benefits of intranasal delivery, and the novel approaches employed for the treatment of epilepsy.
