摘要

Dear Sir,We read with interest the article of Van Den Berge et al. (1) which showed significant bronchoprotection against AMP (adenosine monophosphate) challenge at 14 and 24 h after a single 1000 mug dose of fluticasone furoate (FF), but only at 14 h after fluticasone propionate (FP). The authors suggest that FF may have a longer duration of action than FP, although they state that the study was not designed to compare the two drugs but only to analyse the difference against placebo. Interestingly for the intranasal formulation both drugs are indicated as a once daily formulation, but with FF being given at half the dose compared to FP. Since inhaled FP is recommended to be given twice daily with a 12 h dosing interval, while inhaled FF is given once daily with a 24 h interval, the more valid comparison at 26 h at trough would have been after a second dose of FP vs after a first dose of FF.
