The Nose as a Route for Therapy: Part 1. Pharmacotherapy

Area of Science:

• Pharmacology
• Otorhinolaryngology
• Drug Delivery Systems

Background:

• The nasal cavity presents unique anatomical and physiological features relevant to drug administration.
• Intranasal drug delivery is increasingly explored for both local and systemic therapeutic applications.
• Understanding nasal structure and function is crucial for optimizing intranasal pharmacotherapy.

Purpose of the Study:

• To review the structure and function of the nose in the context of intranasal pharmacotherapy.
• To elucidate the advantages of the nasal route for drug delivery.
• To explore the potential of intranasal administration for treating nose and sinus diseases.

Main Methods:

• Literature review of scientific articles on nasal anatomy, physiology, and intranasal drug delivery.
• Analysis of the protective mechanisms within the nasal cavity.
• Evaluation of the pharmacokinetic and pharmacodynamic aspects of intranasal drug administration.

Main Results:

• The nose offers an accessible and rapid route for local treatment of nasal and sinus diseases.
• Intranasal delivery allows for lower doses and fewer adverse effects compared to systemic administration.
• Nasal structures provide protection against drug degradation and facilitate efficient absorption.

Conclusions:

• Intranasal pharmacotherapy is a viable and advantageous route for targeted drug delivery.
• The nasal environment possesses ideal characteristics for effective medication administration.
• Further research into intranasal drug delivery can optimize treatment for various conditions.
