Breakthroughs in Nasal Drug Repositioning: What’s Next?


Nasal drug repositioning, a term gaining momentum in the pharmaceutical realm, signifies the repurposing of existing nasal drugs for novel therapeutic indications. This approach holds significant promise in revolutionizing drug development strategies and enhancing patient outcomes.

Evolution of Nasal Drug Delivery

Historically, CNS drug delivery has witnessed a remarkable evolution, transitioning from traditional remedies to sophisticated formulations. Presently, it stands as a preferred route for drug administration due to its numerous advantages such as rapid onset of action, avoidance of first-pass metabolism, and non-invasiveness. However, challenges persist, including issues related to formulation stability and mucociliary clearance.

Nasal Drug Repositioning: A Game-Changer

Nasal drug repositioning emerges as a game-changer in pharmaceutical innovation. By leveraging existing nasal drugs, researchers can expedite the drug development process and mitigate risks associated with novel compound discovery. Case studies demonstrate the efficacy of this approach, showcasing successful repurposing endeavors that have led to improved treatment options for various medical conditions.

Mechanisms of Systemic Nasal Drug Delivery

The nasal mucosa serves as a gateway for systemic drug delivery, offering direct access to the bloodstream. Moreover, its proximity to the central nervous system (CNS) presents opportunities for bypassing the blood-brain barrier, facilitating targeted delivery of therapeutics for neurological disorders.

The Role of OINDP in Nasal Drug Repositioning

Orally Inhaled and Nasal Drug Products (OINDP) play a pivotal role in Nasal drug repositioning endeavors. Through optimized formulations and delivery techniques, researchers can enhance the bioavailability and efficacy of repurposed drugs, thereby maximizing their therapeutic potential.

Challenges and Future Directions

Despite its promise, nasal drug repositioning faces regulatory and safety challenges that necessitate careful consideration. Addressing these concerns, alongside embracing emerging technologies and innovative research methodologies, will pave the way for future breakthroughs in this field.


In conclusion, nasal drug repositioning represents a paradigm shift in pharmaceutical innovation, offering a cost-effective and expedited approach to drug development. With continued advancements and strategic collaborations, the future holds immense promise for the repositioning of nasal drugs to address unmet medical needs.
