title: Comparison of the efficacy of inhaled fluticasone propionate, 880 microg/day, with flunisolide, 1500 microg/day, in moderate-to-severe persistent asthma.
abstract: BACKGROUND
  Inhaled corticosteroids have become the mainstay of asthma therapy. Few studies however, have compared inhaled steroids in children. We compared the efficacy of inhaled fluticasone propionate (FP), 880 microg/day (2 puffs of 220 microg/puff, BID) with inhaled flunisolide (FLU), 1500 microg/day (3 puffs of 250 microg/puff, BID).
  
  
  METHODS
  Thirty children with moderate to severe asthma, mean age 12.7 years (range 10 to 17 years), mean duration of asthma 8.4 years, initially received flunisolide 1500 microg/day for 1 year, and then were switched to fluticasone propionate 880 microg/day and followed for an additional year. Pulmonary function tests (PFTs) were monitored and analyzed before and after the switch for the duration of study. Mean percent predicted for age values for FVC, FEV1, FEF25-75%, and FEFR were compared at 1 month, 2 to 6-month intervals, and 7 to 12-month intervals and during the same season of the year. Pulmonary function tests within 3 weeks of an exacerbation were not included in the study. The number of asthma exacerbations, emergency room visits, hospital admissions, and number of school days lost were also compared.
  
  
  RESULTS
  There was significant improvement in mean asthma exacerbations/patient/year (1.7 +/- 1.66 SD) versus (4 +/- 2.6) (P < .0002); mean emergency room visits/patient/year (0.23 +/- 0.62) versus (1.2 +/- 1.74) (P = .004); mean hospital admissions for asthma/patient/year (0.2 +/- 0.61) versus (1.13 +/- 1.45) (P < .0002); and number of school days lost/patient/year (1.4 +/- 2.38) versus (7.93 +/- 6.7) (P < .0002) while patients were receiving fluticasone propionate as compared with flunisolide. Also, the mean percent values predicted for age in all time-periods (at 1 month, 2 to 6 months, and 7 to 12 months) revealed significant improvement in FEV1 and FEF25-75% (P < .05 for both parameters). As PFT can be affected by seasonal changes, PFT parameters were compared during the same season of the year and significant improvement in FVC and FEV1 was observed in all seasons while patients were receiving fluticasone propionate (FP) compared with flunisolide (FLU) (P < .05 for all parameters). Significant improvement in PEFR and FEF25-75% was observed only in spring and summer season.
  
  
  CONCLUSIONS
  Fluticasone propionate 880 microg/day improved lung function and quality of life in adolescents with moderate-to-severe asthma when compared with flunisolide 1500 microg/day.
