Nasal Drug Delivery: Challenges and Future Opportunities

Dear Colleagues,

In recent years, research and development has gained a new focus of attention: auspicious intranasal (IN) drug delivery. It is an efficient way to deliver drugs into the systemic circulation via the nose-to-blood delivery route and to the brain via the nose-to-brain route. The latter also holds the added value of bypassing the blood–brain barrier, allowing quick access and direct entry to the central nervous system There are multiple challenges regarding IN drug delivery, which concern the physicochemical properties of active substances and how can we conquer transmucosal drug delivery. Various approaches, such as in the field of nanotechnology, have been previously proposed to overcome the challenges of the IN drug delivery route; however, there are still certain areas uncharted.

The scope of this Special Issue covers the present original ideas and technologies regarding solutions for the successful delivery of drugs through the IN drug delivery route and how novel technologies can advance the field of nose-to-blood or nose-to-brain transport routes. Manuscripts related to quality assurance and the regulatory environment concerning this topic are welcomed.

We are looking forward to your related publications, hoping that this Special Issue will improve our understanding of how the IN drug delivery systems can advance with future technologies.
