Umeclidiniumdrug info

ANORO ELLIPTA is an inhalation powder drug product for delivery of a combination of umeclidinium (an anticholinergic) and vilanterol (a LABA) to patients by oral inhalation. Umeclidinium bromide has the chemical name 1-[2-(benzyloxy)ethyl]-4-(hydroxydiphenylmethyl)-1-azoniabicyclo[2.2.2]octane bromide and the following chemical structure: Umeclidinium bromide is a white powder with a molecular weight of 508.5, and the empirical formula is C 29 H 34 NO 2

Br (as a quaternary ammonium bromide compound). It is slightly soluble 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. ANORO ELLIPTA is a light grey and red plastic inhaler containing 2 foil blister strips. Each blister on one strip contains a white powder blend of micronized umeclidinium bromide (74.2 mcg equivalent to 62.5 mcg of umeclidinium), magnesium stearate (75 mcg), and lactose monohydrate (to 12.5 mg), 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 (to 12.5 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, ANORO ELLIPTA delivers 55 mcg of umeclidinium and 22 mcg of vilanterol per dose when tested at a flow rate of 60 L/min for 4 seconds. In adult subjects 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). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. Umeclidinium bromide chemical structure Vilanterol trifenatate chemical structure
