BACKGROUND: Inhaled fluticasone propionate (FP) is a relatively new inhaled corticosteroid for the treatment of asthma. OBJECTIVES: 1. To assess efficacy and safety outcomes in studies that compared FP to placebo for treatment of chronic asthma.2. To explore the presence of a dose-response effect. SEARCH STRATEGY: We searched the Cochrane Airways Group Trial Register (January 2004), reference lists of articles, contacted trialists and searched abstracts of major respiratory society meetings (1997-2004). SELECTION CRITERIA: Randomised trials in children and adults comparing FP to placebo in the treatment of chronic asthma. Two reviewers independently assessed articles for inclusion and methodological quality. DATA COLLECTION AND ANALYSIS: Two reviewers extracted data. Quantitative analyses where undertaken using RevMan Analyses 4.2.7. MAIN RESULTS: Sixty eight studies met the inclusion criteria (11, 104 participants). Methodological quality was high. In non-oral steroid treated asthmatics with mild and moderate disease FP resulted in improvements from baseline compared with placebo across all dose ranges (100 to 1000 mcg/d) in FEV1 (between 0.13 to 0.45 litres); morning PEF (between 27 and 47 L/min); symptom scores (based on a standardised scale, between 0.5 and 0.85); reduction in rescue beta-2 agonist use (between 1.2 and 2.2 puffs/d). High dose FP reduced the number of patients dependent on prednisolone: FP 1000-1500 mcg/d Peto Odds Ratio 0.07 (95% CI 0.05 to 0.10). FP at all doses led to a greater likelihood of sore throat, hoarseness and oral Candidiasis, but 21 patients would need to be treated for one extra to develop Candidiasis (FP 500 mcg/day), whilst only three or four patients need to be treated to avoid one extra patient being withdrawn due to lack of efficacy at all doses of FP. AUTHORS' CONCLUSIONS: Doses of FP in the range 100-1000 mcg/d are effective. In most patients with mild-moderate asthma improvements with low dose FP are only a little less than those associated with high doses when compared with placebo. High dose FP appears to have worthwhile oral-corticosteroid reducing properties. FP use is accompanied by an increased likelihood of oropharyngeal side effects.
