Abstract
OBJECTIVES: Intranasal corticosteroids (INCs) are the most effective modality for treating allergic rhinitis and their sensory attributes are important in patient compliance. This study aimed to compare the sensory attributes (scent, immediate taste, aftertaste, run down to throat, nose run off, soothing feel, nasal irritation, and urge to sneeze) and immediate response to the new intranasal steroid, ciclesonide (CIC), with fluticasone propionate (FLP) in allergic rhinitis. MATERIALS AND METHODS: A randomized, double blind, single dose, crossover study was done with 74 patients presenting with acute allergic rhinitis. Eligible subjects were randomized in 1:1 ratio to one of the two treatment sequences - CIC followed by FLP or vice versa. Sensory attributes were assessed using a questionnaire to score each item on a seven-point Likert scale, immediately and 2 min after dosing. Total nasal symptom score (TNSS) was calculated to evaluate immediate efficacy 10 min after first drug administration. Overall preference was recorded 10 min after the second drug administration. Patients were queried about treatment emergent adverse events following study drug administration and also 24 h later over the phone. RESULTS: Patients (58% males; pooled median age 32 years [Interquartile range, IQR, 25-41]; pooled median symptom duration 24 months [IQR 12-72]) preferred FLP over CIC nasal spray overall (55.41% vs. 25.68%, P = 0.007) and also with respect to attributes of scent, soothing feel, and nasal irritation. There was no statistically significant difference in immediate efficacy. Two patients reported mild headache following CIC first, while three felt mild headache, one dizziness, and one nasal congestion following FLP first administration. There were no delayed adverse events. CONCLUSIONS: There was no difference in immediate outcome following use of either of the two INCs. FLP was preferred over CIC with respect to scent, soothing feel and nasal irritation, and also overall. There were no significant adverse events.
