This study quantitatively compared the efficacy of fluticasone furoate (FF) and fluticasone propionate (FP) in adolescents and adults with asthma. The study found that the efficacy of both drugs reached a plateau within 2 weeks, but FP reached a plateau at the maximum evaluated dose while FF did not show a plateau effect. The secondary outcomes showed similar relative effects for both drugs compared to placebo, without obvious dose-effect relationships. This quantitative evaluation provides necessary information for asthma-related guidelines.
This study aimed to quantitatively compare the efficacy of fluticasone furoate (FF) and fluticasone propionate (FP) in adolescents and adults with asthma. We searched the PubMed and EMBASE databases for placebo-controlled trials that met the inclusion criteria. Pharmacodynamic models were established to describe the time-course of the primary outcome (trough forced expiratory volume in the first second [FEV1]). Secondary outcomes (asthma symptoms, quality of life and exacerbations) were also compared via a meta-analysis. A total of 14 articles were included in the analysis, involving 6640 subjects. The efficacy plateau of the two drugs could be reached in 2 weeks. The changes from the baseline in trough FEV1 (95% CI) at week 2 of FF at 200 and 100 mu g/day were 0.168 L (0.064-0.199) and 0.127 L (0.048-0.163), respectively. The changes from the baseline in trough FEV1 (95% CI) at week 2 of FP at 1000, 500, 250 and 100 mu g/day were 0.133 L (0.049-0.171), 0.127 L (0.043-0.163), 0.117 L (0.039-0.150) and 0.093 L (0.032-0.129), respectively. The efficacy of FP had reached a plateau at the maximum evaluated dose (1000 mu g/day), while a plateau effect was not seen at the maximum evaluated dose of FF (200 mu g/day). In terms of secondary outcomes, the relative effects of the two drugs relative to the placebo were similar and did not show obvious dose-effect relationships. In this study, the time-course and dose-effect characteristics of FP, FF and placebo were quantitatively evaluated, providing necessary quantitative information for asthma-related guidelines.
