Comparative efficacy of steroid nasal spray versus antihistamine nasal spray in allergic rhinitis.

This prospective randomized case controlled study was conducted to determine the efficacy of antihistamine (azelastine) nasal spray and compare it to steroid (beclomethasone) nasal spray on the symptoms of allergic rhinitis. Seventy five symptomatic patients of allergic rhinitis were included in this study. Diagnosis was made on the basis of history and physical examination. The patients were divided into three groups randomly. Group A was treated with Azelastine nasal spray, Group B was treated with Beclomethasone nasal spray and Group C was control group and only treated with steam inhalation. Efficacy of the treatment was assessed in the terms of Total Rhinitis Symptom Complex (TSC) scores and individual symptom score which was calculated on the basis of Okuda's grading system. Base line total symptom complex (TSC) scores were reduced in group A and group B by 84.0% after 4 week treatment whereas in group C it was reduced by only 38.0%. Decrease in mean score for sneezing was 95.0% in group A and group B whereas it was only 28.3% in group C. Similarly decrease in mean score for rhinorrhoea in azelastine group was 94.4% and in beclomethasone group was 95.3% in comparison to steam inhalation group where it was 25.0%. Only the beclomethasone reduced nasal stuffiness score significantly by 95.0%. No significant adverse effects of the drugs were observed. The present study establishes the relative efficacy and tolerability ofazelastine nasal spray as compared to beclomethasone nasal spray in symptomatic patients of allergic rhinitis.
