Intranasal drug delivery offers a promising route for central nervous system diseases, bypassing the blood-brain barrier for enhanced therapeutic outcomes. This method leverages nasal anatomy for improved drug absorption and patient compliance.
Area of Science:
- Nanotechnology
- Pharmacology
- Neuroscience
Background:
- Nanotechnology has advanced drug delivery for central nervous system (CNS) and neurodegenerative diseases.
- Intranasal drug delivery is a promising approach utilizing nasal cavity's unique characteristics.
Purpose of the Study:
- To explore intranasal drug delivery principles and their impact on CNS diseases.
- To review advancements in formulation strategies and address challenges in nasal drug delivery.
Main Methods:
- Review of scientific literature on intranasal drug delivery principles.
- Analysis of nasal anatomy's influence on drug bioavailability.
- Examination of formulation strategies and challenges like mucociliary clearance.
Main Results:
- Intranasal delivery bypasses the blood-brain barrier, enabling direct CNS targeting.
- The nasal mucosa's vascularization promotes rapid systemic drug absorption.
- Formulation advancements aim to overcome challenges like enzymatic degradation.
Conclusions:
- Intranasal drug delivery offers efficient systemic and CNS targeting for various diseases.
- Understanding nasal anatomy and delivery mechanisms is key to optimizing intranasal therapeutics.
- Overcoming challenges can enhance the efficacy of intranasal medications.

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
