Background: Allergic rhinitis is an IgE mediated hypersensitivity reaction of the nasal mucosa characterised by nasal discharg, obstruction, and pruritus. Patients and methods: In this study, 43 patients with perenneal allergic rhinitis were enrolled in order to compare the efficacy of Fluticasone Propionate (FP), a corticosteroid nasal spray, with Cetirizine, a systemic oral antihistaminic preparation, wich is suposed to have nonsteroidal antiinflammatory activity. Cetirizine (10 mg daily as a single dose) was administered to 22 patient for 45 days. On the other hand, FP (400 μg/day) was administered into each nostril twice a day in the remaining 21 patients for 45 days. Skin test was obtained from each patient before therapy. Total eosinophil count, eosinophil count in nasal smear, electrorhinomanometric investigation, PGE2 and ratio of LTC4 to LTD4 both in the serum and in the nasal secretions were determined before and after therapy. In addition, percentage of eosinophils, and mast cells count in the biopsy specimens taken from anterior edge of middle choncha were evaluated before and after therapy, and than the results were graded for each patients. Results: When we compared the eosinophil count in nasal smear, eosinophil percentage and total eosinophil parameters between two groups, it was shown that FP was more effective than Cetirizine. On the other hand, when we compared the ratio of LTC4 to LTD4 in serum and nasal smear, level of PGE2 and mast cell and nasal airway resistance measured by ERM, there were non statistical difference between two groups. Conclusion: These results suggest that FP and Cetirizine may be used alternatively in case of an adverse reaction to any of them.
