A comparison of budesonide and beclomethasone dipropionate sprays in the treatment of seasonal allergic rhinitis.

Intranasal budesonide and beclomethasone dipropionate (BDP), each administered as aqueous, aerosol formulations at dosages of 200 micrograms twice a day, morning and evening, were compared over a 3-week period in a randomized, parallel group study of 88 adults with seasonal allergic rhinitis. Budesonide treatment produced significantly lower mean symptom scores for the whole study compared with BDP for runny nose, itchy nose and sneezing (P < 0.05). The difference in nasal symptom scores produced by budesonide in comparison with BDP was particularly great towards the end of the treatment period. The budesonide-treated group also had lower scores for nasal blockage and two eye symptoms (runny and sore eyes), but the differences noted were not significant. Adverse events recorded by both groups were mild and transient. In conclusion, aqueously administered budesonide is likely to be of more clinical value than BDP for the control of seasonal allergic rhinitis.
