Comparison of the efficacy of budesonide and fluticasone propionate aqueous nasal spray for once daily treatment of perennial allergic rhinitis.

BACKGROUND

Intranasal corticosteroids, such as budesonide and fluticasone propionate, are widely prescribed in the treatment of perennial allergic rhinitis. Once daily budesonide dry powder and fluticasone propionate aqueous suspension have been found to provide similar efficacy in controlling symptoms of perennial allergic rhinitis.

OBJECTIVE

The purpose of this study was to assess the efficacy and safety of treatment with once daily budesonide aqueous nasal spray.

METHODS

This study involved a multicenter, blinded, randomized, parallel-group, placebo-controlled trial of adults with perrenial allergic rhinitis. Patients (n = 273) recorded daily nasal symptoms for 8 to 14 days (baseline) and 6 weeks (treatment).

RESULTS

Budesonide decreased combined symptoms to a significantly greater extent than did fluticasone (P =.03); both treatments significantly decreased mean combined nasal symptoms scores compared with placebo. Of the 3 nasal symptoms assessed (ie, nasal blockage, runny nose, and sneezing), nasal blockage was significantly (P =. 009) more decreased with budesonide compared with fluticasone. Both treatments also significantly improved runny nose and sneezing compared with placebo. Improvement in combined nasal symptom scores of the budesonide-treated group reached statistical significance within 36 hours compared with placebo (P =.01); in those patients treated with fluticasone, significant improvement compared with placebo was first observed within 60 hours. Adverse events were mild and transient.

CONCLUSIONS

Once daily budesonide aqueous nasal spray, 256 microgram, was significantly better in controlling the symptoms of perrenial allergic rhinitis than once daily fluticasone propionate, 200 microgram, especially nasal blockage. Both treatments were superior to placebo. Budesonide may have a faster onset of action than fluticasone.
