Recent advances in the treatment of rhinitis and rhinosinusitis.

Current rhinitis treatment is unsatisfactory for many patients, possibly because monotherapy is employed, without regard to the major presenting symptom. Recognition of the impact of rhinitis on quality of life and on associated disorders such as asthma has led to the development of guidelines, use of which has been shown to improve symptom control and quality of life compared to unguided therapy. The role of antihistamines, topical corticosteroids and anti-leukotrienes is discussed.
