fluticasone furoate and vilanterol trifenatate - Generic Medications

BREO ELLIPTA is an inhalation powder drug product for delivery of a combination of fluticasone furoate (an ICS) and vilanterol (a LABA) 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. Vilanterol trifenatate has the chemical name triphenylacetic acid-4-{(1 R )-2-[(6-{2-[2,6-dicholorobenzyl)oxy]ethoxy}hexyl)amino]-1-hydroxyethyl}-2-(hydroxymethyl)phenol (1:1) and the following chemical structure: Vilanterol trifenatate is a white powder with a molecular weight of 774.8, and the empirical formula is C 24 H 33 Cl 2 NO 5 •C 20 H 16 O 2 . It is practically insoluble in water. BREO ELLIPTA is a light grey and pale blue plastic inhaler containing 2 foil blister strips. Each blister on one strip contains a white powder blend of micronized fluticasone furoate (50, 100, or 200 mcg) and lactose monohydrate (12.5, 12.4 or 12.3 mg, respectively), and each blister on the other strip contains a white powder blend of micronized vilanterol trifenatate (40 mcg equivalent to 25 mcg of vilanterol), magnesium stearate (125 mcg), and lactose monohydrate (12.34 mg). The lactose monohydrate contains milk proteins. After the inhaler is activated, the powder within both blisters is exposed and ready for dispersion into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, BREO ELLIPTA delivers 46, 92 or 184 mcg of fluticasone furoate and 22 mcg of vilanterol per dose when tested at a flow rate of 60 L/min for 4 seconds. In adult patients with obstructive lung disease and severely compromised lung function (COPD with FEV 1 /FVC <70% and FEV 1 <30% predicted or FEV 1 <50% predicted plus chronic respiratory failure), mean peak inspiratory flow through the ELLIPTA inhaler was 66.5 L/min (range: 43.5 to 81.0 L/min). In adult patients with severe asthma, mean peak inspiratory flow through the ELLIPTA inhaler was 96.6 L/min (range: 72.4 to 124.6 L/min). In pediatric patients with asthma aged 5 to 11 years, mean peak inspiratory flow through the ELLIPTA inhaler was 60.6 L/min (range: 36.3 to 82.5 L/min). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. fluticasone furoate chemical structure vilanterol trifenatate chemical structure
