Timing of once-daily fluticasone furoate (FF) was studied for efficacy in asthma.
Morning (AM) or evening (PM) FF100 μg, and placebo were compared.
Forced expiratory volume in 1 s (FEV1) was measured on Day 14.
AM and PM dosing were comparable for 24-h and pre-treatment FEV1.
There was also no difference in adverse event incidence between AM and PM dosing.
