Combination therapy in allergic rhinitis: What works and what does not work

Area of Science:

• Otolaryngology
• Allergy and Immunology
• Pharmacology

Background:

• Allergic rhinitis (AR) and other rhinitis subtypes represent a significant and growing public health burden in the U.S.
• These conditions incur substantial direct and indirect healthcare costs, exacerbated by diagnostic delays, suboptimal treatments, and poor adherence.
• Many patients with AR seek relief from over-the-counter (OTC) medications, often experiencing unsatisfactory outcomes.

Purpose of the Study:

• To emphasize the critical need for accurate diagnosis and effective treatment strategies in managing rhinitis.
• To highlight the advantages of current combination therapies for complex rhinitis cases.
• To advocate for further research into the underlying mechanisms and biomarkers of specific rhinitis subtypes.

Main Methods:

• Review of current clinical challenges in rhinitis diagnosis and management.
• Analysis of the role of OTC medications and patient dissatisfaction.
• Evaluation of existing combination therapies (e.g., azelastine/fluticasone, intranasal corticosteroids/decongestants).

Main Results:

• Accurate diagnosis and timely initiation of appropriate treatments are essential for optimal patient outcomes and quality of life.
• Combination therapies offer significant benefits for managing complex rhinitis phenotypes.
• Current research gaps exist in understanding mixed rhinitis and nonallergic vasomotor rhinitis.

Conclusions:

• Personalized treatment approaches are necessary for effective rhinitis management.
• Combination therapies are valuable tools for addressing complex rhinitis.
• Further investigation into pathomechanisms and biomarkers is required for developing novel, targeted therapies for understudied rhinitis subtypes.
