Chronic Rhinitis: Prevalence, Classification, and Standard Therapies

Chronic rhinitis (CR) presents with symptoms such as rhinorrhea, nasal congestion, itching, and sneezing. Epidemiological surveys indicate that roughly 10–40 % of the population experiences the condition, making it a common disorder. CR is categorized according to the presence of a specific IgE response to causative allergens: allergic rhinitis (AR) when IgE‑mediated, and non‑allergic rhinitis (NAR) when such a response is absent. The principal pharmacologic agents employed for both AR and NAR include antihistamines, intranasal corticosteroids, nasal decongestants, and leukotriene‑receptor antagonists.
