    Abstract:
    The currently available beclomethasone dipropionate (BDP) metered-dose nasal aerosol spray is considered uncomfortable by some patients because of the force of delivery. It was compared for efficacy and acceptability in a double-blind study with a new aqueous suspension BDP spray for the treatment of seasonal allergic rhinitis in 44 symptomatic patients aged 12 to 43 years. After 7 days of baseline evaluation, every patient was given both an aerosol canister and an aqueous spray bottle each containing either BDP, 42 mcg per spray, or placebo (P). For 15 days the patient sprayed each nostril twice a day with one spray of suspension (BDP or P) followed 5 minutes later by one spray of aerosol (P or BDP). Patients were evaluated before the study medications were started (day 1) and on days 4, 8, and 15 for nasal and eye symptoms. Nasal cytologic specimens were examined on days 1 and 15, and rhinomanometry was performed on days 1, 8, and 15 of the study. Topical BDP by both methods of delivery was rapidly effective in decreasing mean nasal obstruction, rhinorrhea, sneezing, and itching symptoms as well as mean eye symptoms with no statistically significant differences between them. Nasal airflow increased with both treatments; rhinomanometry significantly correlated with subjective nasal obstruction scores. Of 34 patients with nasal eosinophils, 74% had fewer eosinophils after treatment. Most patients (84%) preferred the aqueous spray over the pressurized aerosol.
