Abstract
Background: 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 as beneficial for delivering antiepileptic
drugs owing to the advantages it offers.
Objective: 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 noninvasiveness
and high vascularity contribute to the high permeability of the nasal mucosa, allowing
rapid drug absorption. This review highlights some promising novel approaches to efficiently deliver
anti-epileptic drugs by employing the nasal route.
Methods: The method includes a collection of data from different search engines like PubMed,
ScienceDirect and SciFinder for obtaining appropriate and relevant literature regarding epilepsy,
intranasal delivery of anti-epileptic agents, and novel therapeutics.
Results: 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 most
efficient ways of formulation for the delivery of anti-epileptics during seizures.
Conclusion: This review intends to provide an understanding of the delivery aspects of antiepileptic
drugs, the benefits of intranasal delivery and the novel approaches employed for the
treatment of epilepsy.
Keywords:
