BACKGROUND: Intranasal corticosteroids are effective for the treatment of allergic rhinitis. Sensory attributes associated with these sprays may affect patient preference and adherence to treatment regimens. OBJECTIVES: These 2 studies compared patients' perceptions of and preferences for specific sensory attributes of budesonide aqueous nasal spray (BANS) and fluticasone propionate nasal spray (FPNS). METHODS: In 2 multicenter, randomized, single-blind (patient), single-dose, 2-period, 1-day crossover studies, adults with mild to moderate allergic rhinitis received single doses of BANS (one 32-pg spray per nostril in both studies, 64-microg total dose) and FPNS (two 50-microg sprays per nostril in study 1, 200-pg total dose; one 50-microg spray per nostril in study 2, 100-microg total dose). Study 1 compared the once-daily recommended starting doses of BANS and FPNS, and study 2 compared BANS with half the once-daily recommended dose of FPNS to balance the number of actuations for delivery of study drug. Patients completed the 23-item Sensory Perceptions Questionnaire and indicated their product preference (if any). RESULTS: A total of 110 women and 71 men in study 1 and 136 women and 54 men in study 2 were randomized to treatment. None had previously used BANS or FPNS. In both studies, fewer patients perceived scent or taste (both P < 0.001 in both studies), forceful spray (P < 0.001 in both studies), and a wet feel in both the nose and throat (study 1, P < 0.004; study 2, P < 0.002) with BANS than with FPNS. In addition, more patients in both studies liked the spray force (study 1, P < 0.01; study 2, P < 0.001) and moisture content in the throat (study 1, P < 0.001; study 2, P < 0.006) of BANS and indicated a greater overall satisfaction with the sensory features of BANS than those of FPNS (study 1, P < 0.001; study 2, P < 0.015). In analyses that included all responding patients, 54.4% of patients in study 1 preferred BANS and 37.8% preferred FPNS (P < 0.022). In study 2, 47.4% preferred BANS and 41.1% preferred FPNS (not significant). Of the 92.2% of patients in study 1 and 88.4% in study 2 who specified a product preference, 59.0% preferred BANS and 41.0% preferred FPNS in study 1 (P = 0.021), and 53.6% preferred BANS and 46.4% preferred FPNS in study 2 (not significant). CONCLUSIONS: On the basis of perceptions of specific sensory attributes reported after 1 administration in these 2 studies, BANS was rated as more pleasing and preferred over the recommended QD starting dose of FPNS, and was also rated as more pleasing than half the QD recommended starting dose of FPNS.
