Summary
For allergic rhinitis, intranasal corticosteroids offer superior relief compared to antihistamines. Combining treatments does not improve outcomes, making intranasal corticosteroids the preferred first-line option.
Area of Science:
- Allergy and Immunology
- Pharmacology
Background:
- The optimal first-line pharmacological treatment for allergic rhinitis, antihistamines versus intranasal corticosteroids, remains debated.
- First-generation antihistamines are seldom used due to adverse effects like sedation and anticholinergic properties.
Purpose of the Study:
- To compare the efficacy and safety of antihistamines and intranasal corticosteroids in treating allergic rhinitis.
- To evaluate the added benefit of combination therapy.
Main Methods:
- Systematic review of clinical evidence comparing antihistamines and intranasal corticosteroids.
- Analysis of safety and efficacy data from comparative studies.
Main Results:
- Intranasal corticosteroids demonstrate superior efficacy over antihistamines for allergic rhinitis symptom relief.
- No significant differences in efficacy or safety were found between different second-generation antihistamines or administration routes.
- Combination therapy with antihistamines and intranasal corticosteroids did not provide additional benefits over intranasal corticosteroids alone.
Conclusions:
- Intranasal corticosteroids are recommended as the preferred first-line treatment for allergic rhinitis due to superior efficacy.
- Current evidence does not support the superiority of antihistamines for allergic conjunctivitis treatment.
