umeclidinium - Generic Medications

INCRUSE ELLIPTA is an inhalation powder drug product for delivery of umeclidinium (an anticholinergic) 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. INCRUSE ELLIPTA is a light grey and light green plastic inhaler containing a foil blister strip. Each blister on the 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). 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, INCRUSE ELLIPTA delivers 55 mcg of umeclidinium 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 forced expiratory volume in 1 second/forced vital capacity [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 67.5 L/min (range: 41.6 to 83.3 L/min). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. incruse-ellipta-spl-graphic-01.jpg
