Abstract:
This letter responds to a recent review on nasal drug delivery systems for brain-targeted therapy. Drawing on first hand experiences as a psychiatrist and migraine patient in Taiwan, the response discusses the practical benefits and challenges of using nasal formulations, such as sumatriptan nasal spray, during ongoing drug shortages. While these formulations offer rapid onset of action, issues related to taste and odor can limit adherence. The letter highlights the potential of advanced technologies like nanocarriers to improve nasal drug delivery and emphasizes the need for patient-centered designs. The correspondence concludes with recommendations for diversifying drug delivery approaches to enhance efficacy and accessibility.

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...
Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
