A COMPARISON OF AQUEOUS SUSPENSIONS OF BUDESONIDE NASAL SPRAY (128 MU-G AND 256 MU-G ONCE-DAILY) AND FLUTICASONE PROPIONATE NASAL SPRAY (200 MU-G ONCE-DAILY) IN THE TREATMENT OF ADULT PATIENTS WITH SEASONAL ALLERGIC RHINITIS

The efficacy of aqueous suspensions of budesonide nasal spray and flut icasone propionate nasal spray, in the treatment of seasonal allergic rhinitis, was compared in a large, placebo-controlled, two-center stud y. A 1-week baseline period was followed by a 4- to 6-week treatment p eriod during which 635 adult patients, aged 18-72 years, were randomiz ed to receive either placebo, budesonide 128 mu g, or 256 mu g once da ily, or fluticasone propionate, 200 mu g once daily. Nasal and eye sym ptoms, overall treatment efficacy and safety assessments were made dur ing the study period. Combined, as well as individual, nasal symptoms were significantly improved in all three active treatment groups compa red with placebo therapy. Treatment with 256 mu g/day of budesonide wa s found to be significantly more effective in reducing the sneezing sc ore compared with 200 mu g/day of fluticasone propionate. Analysis of symptom scores on days when the pollen count was greater than 10 grain s/m(3) revealed 256 mu g/day of budesonide therapy to be significantly more effective in reducing combined symptom scores as well as the ind ividual scores for sneezing and runny nose, compared with 200 mu g/day fluticasone propionate. The higher dose of budesonide (256 mu g/day) was also more effective than the lower dose (128 mu g/day) in reducing sneezing scores and statistical significance was almost reached for t he reduction in combined symptom and runny nose scores. Substantial or total control of symptoms was achieved by 31.4%, 85.3%, 88.4%, and 81 .9% of patients receiving placebo, 128 mu g/day of budesonide, 256 mu g/day of budesonide, and 200 mu g/day of fluticasone propionate, respe ctively. The incidence of adverse events was low in all treatment grou ps. In conclsion, both budesonide and fluticasone propionate treatment s were effective and well-tolerated in the treatment of seasonal aller gic rhinitis. However, 256 mu g/day of budesonide tended to be more ef fective than 200 mu g/day of fluticasone propionate and 128 mu g/day o f budesonide, especially when patients were exposed to a higher pollen load.
