Fluticasone Propionate/Salmeterol DISKUS inhalation powder 100/50 mcg, Fluticasone Propionate/Salmeterol DISKUS inhalation powder 250/50 mcg, and Fluticasone Propionate/Salmeterol DISKUS inhalation powder 500/50 mcg are combinations of fluticasone propionate and salmeterol xinafoate. One active component of Fluticasone Propionate/Salmeterol DISKUS is fluticasone propionate, a corticosteroid having the chemical name S- (fluoromethyl) 6α,9-difluoro-11β,17-dihydroxy-16α-methyl-3-oxoandrosta-1,4-diene-17β-carbothioate, 17-propionate and the following chemical structure: Fluticasone propionate is a white powder with a molecular weight of 500.6, and the empirical formula is C 25 H 31 F 3 O 5 S. It is practically insoluble in water, freely soluble in dimethyl sulfoxide and dimethylformamide, and slightly soluble in methanol and 95% ethanol. The other active component of Fluticasone Propionate/Salmeterol DISKUS is salmeterol xinafoate, a beta 2 -adrenergic bronchodilator. Salmeterol xinafoate is the racemic form of the 1-hydroxy-2-naphthoic acid salt of salmeterol. It has the chemical name 4-hydroxy-α 1 -[[[6-(4-phenylbutoxy)hexyl]amino]methyl]-1,3-benzenedimethanol, 1-hydroxy-2-naphthalenecarboxylate and the following chemical structure: Salmeterol xinafoate is a white powder with a molecular weight of 603.8, and the empirical formula is C 25 H 37 NO 4 •C 11 H 8 O 3 . It is freely soluble in methanol; slightly soluble in ethanol, chloroform, and isopropanol; and sparingly soluble in water. Fluticasone Propionate/Salmeterol DISKUS is a purple plastic inhaler containing a foil blister strip. Each blister on the strip contains a white powder mix of micronized fluticasone propionate (100, 250, or 500 mcg) and micronized salmeterol xinafoate salt (72.5 mcg, equivalent to 50 mcg of salmeterol base) in 12.5 mg of formulation containing lactose monohydrate (which contains milk proteins). After the inhaler is activated, the powder is dispersed into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, Fluticasone Propionate/Salmeterol DISKUS delivers 93, 233, and 465 mcg of fluticasone propionate and 45 mcg of salmeterol base per blister from Fluticasone Propionate/Salmeterol DISKUS inhalation powder 100/50 mcg, Fluticasone Propionate/Salmeterol DISKUS inhalation powder 250/50 mcg, and Fluticasone Propionate/Salmeterol DISKUS inhalation powder 500/50 mcg, respectively, when tested at a flow rate of 60 L/min for 2 seconds. In adult subjects with obstructive lung disease and severely compromised lung function (mean FEV 1 20% to 30% of predicted), mean peak inspiratory flow (PIF) through the DISKUS inhaler was 82.4 L/min (range: 46.1 to 115.3 L/min). Inhalation profiles for adolescent (N = 13, aged 12 to 17 years) and adult (N = 17, aged 18 to 50 years) subjects with asthma inhaling maximally through the DISKUS inhaler show mean PIF of 122.2 L/min (range: 81.6 to 152.1 L/min). Inhalation profiles for pediatric subjects with asthma inhaling maximally through the DISKUS inhaler show a mean PIF of 75.5 L/min (range: 49.0 to 104.8 L/min) for the 4-year-old subject set (N = 20) and 107.3 L/min (range: 82.8 to 125.6 L/min) for the 8-year-old subject set (N = 20). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. Fluticasone propionate chemical structure Salmeterol xinafoate chemical structure

It is freely soluble in methanol; slightly soluble in ethanol, chloroform, and isopropanol; and sparingly soluble in water. Fluticasone Propionate/Salmeterol DISKUS is a purple plastic inhaler containing a foil blister strip. Each blister on the strip contains a white powder mix of micronized fluticasone propionate (100, 250, or 500 mcg) and micronized salmeterol xinafoate salt (72.5 mcg, equivalent to 50 mcg of salmeterol base) in 12.5 mg of formulation containing lactose monohydrate (which contains milk proteins). After the inhaler is activated, the powder is dispersed into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, Fluticasone Propionate/Salmeterol DISKUS delivers 93, 233, and 465 mcg of fluticasone propionate and 45 mcg of salmeterol base per blister from Fluticasone Propionate/Salmeterol DISKUS inhalation powder 100/50 mcg, Fluticasone Propionate/Salmeterol DISKUS inhalation powder 250/50 mcg, and Fluticasone Propionate/Salmeterol DISKUS inhalation powder 500/50 mcg, respectively, when tested at a flow rate of 60 L/min for 2 seconds. In adult subjects with obstructive lung disease and severely compromised lung function (mean FEV 1 20% to 30% of predicted), mean peak inspiratory flow (PIF) through the DISKUS inhaler was 82.4 L/min (range: 46.1 to 115.3 L/min). Inhalation profiles for adolescent (N = 13, aged 12 to 17 years) and adult (N = 17, aged 18 to 50 years) subjects with asthma inhaling maximally through the DISKUS inhaler show mean PIF of 122.2 L/min (range: 81.6 to 152.1 L/min). Inhalation profiles for pediatric subjects with asthma inhaling maximally through the DISKUS inhaler show a mean PIF of 75.5 L/min (range: 49.0 to 104.8 L/min) for the 4-year-old subject set (N = 20) and 107.3 L/min (range: 82.8 to 125.6 L/min) for the 8-year-old subject set (N = 20). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. Fluticasone propionate chemical structure Salmeterol xinafoate chemical structure
