Allergic rhinitis is a disorder resulting from an immunological abnormality in which atopic individuals produce IgE to allergens (e.g. Pollen, house dust mites, animal dander and moulds). IgE activates mast cells, which respond by releasing inflammatory mediators. Histamine stimulates the early symptoms, predominantly mucus production, nasal itching and sneezing. Leukotrienes and cytokines attract and activate eosinophils to cause allergic inflammation, which is primarily responsible for nasal blockage [1].
