The Comprehensive Review: Exploring Future Potential of Nasopulmonary Drug Delivery Systems for Nasal Route Drug Administration

Abstract

This comprehensive review aims to explore the future potential of nasopulmonary drug delivery systems for the administration of drugs through the nasal route. Nasal drug delivery has gained significant attention due to its numerous advantages, including rapid absorption, avoidance of first-pass metabolism, and non-invasive administration. This review provides an overview of the nasal anatomy and physiology, highlighting the factors influencing drug absorption and bioavailability. Additionally, it discusses the various types of nasopulmonary drug delivery systems, such as nasal sprays, powders, and gels, along with their advantages and limitations. Furthermore, the review delves into the challenges associated with nasal drug delivery, including mucociliary clearance, nasal irritation, and formulation issues. The potential applications of nasopulmonary drug delivery systems in the treatment of various diseases, such as allergies, respiratory disorders, and systemic conditions, are also discussed. Finally, the review concludes with an outlook on the future prospects of nasopulmonary drug delivery systems, emphasising the need for further research and development to optimise their efficacy and safety.
