Fluticasone Propionate DISKUS inhalation powder is a dry powder inhaler for oral inhalation. The active component of Fluticasone Propionate DISKUS 50 mcg, Fluticasone Propionate DISKUS 100 mcg, and Fluticasone Propionate DISKUS 250 mcg 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. Fluticasone Propionate DISKUS is an orange plastic inhaler containing a foil blister strip. Each blister on the strip contains a white powder mix of micronized fluticasone propionate (50, 100, or 250 mcg) 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 DISKUS delivers 46, 94, and 229 mcg of fluticasone propionate from Fluticasone Propionate DISKUS 50 mcg, Fluticasone Propionate DISKUS 100 mcg, and Fluticasone Propionate DISKUS 250 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). In children with asthma aged 4 and 8 years, mean PIF through Fluticasone Propionate DISKUS was 70 and 104 L/min, respectively (range: 48 to 123 L/min). The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile. Fluticasone propionate chemical structure
