ARNUITY ELLIPTA is an inhalation powder drug product for delivery of fluticasone furoate (an ICS) to patients by oral inhalation. Fluticasone furoate, a synthetic trifluorinated corticosteroid, has the chemical name (6α,11β,16α,17α)-6,9-difluoro-17-{[(fluoro-methyl)thio]carbonyl}-11-hydroxy-16-methyl-3-oxoandrosta-1,4-dien-17-yl 2-furancarboxylate and the following chemical structure: Fluticasone furoate is a white powder with a molecular weight of 538.6, and the empirical formula is C 27 H 29 F 3 O 6 S. It is practically insoluble in water. ARNUITY ELLIPTA is a light grey and orange plastic inhaler containing a foil blister strip. Each blister on the strip contains a white powder blend of micronized fluticasone furoate (50, 100, or 200 mcg) and lactose monohydrate (12.45, 12.40, or 12.30 mg, respectively) for a total powder blend of 12.5 mg per blister. The lactose monohydrate contains milk proteins. After the inhaler is activated, the powder within the blister is exposed and ready for dispersion into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, ARNUITY ELLIPTA 50 mcg, ARNUITY ELLIPTA 100 mcg, and ARNUITY ELLIPTA 200 mcg delivers 46, 90, and 182 mcg, respectively, of fluticasone furoate per dose when tested at a flow rate of 60 L/min for 4 seconds. In adult subjects with asthma and a mean FEV 1 of 2.55 L/sec (range: 1.63 to 3.97 L/sec), mean peak inspiratory flow through the ELLIPTA inhaler was 103.2 L/min (range: 71.2 to 133.1 L/min). In pediatric subjects with asthma aged 5 to 11 years and a mean peak expiratory flow rate of 242 L/min (range: 130 to 420 L/min), mean peak inspiratory flow through the ELLIPTA inhaler was 51.8 L/min (range: 26.8 to 89.9 L/min). Therefore, the ELLIPTA inhaler is able to deliver the dose of fluticasone furoate in patients with asthma. The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. fluticasone furoate chemical structure
