Flovent Diskus
FLOVENT helps prevent symptoms of asthma, however, FLOVENT does not treat sudden symptoms of an asthma attack, such as wheezing, cough, shortness of breath, and chest pain or tightness. Always have a fast-acting bronchodilator medicine (rescue inhaler) with you to treat sudden symptoms. FLOVENT DISKUS inhalation powder is a dry powder inhaler for oral inhalation. The active component of FLOVENT DISKUS 50 mcg, FLOVENT DISKUS 100 mcg, and FLOVENT 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-17βcarbothioate, 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 C25H31F3O5S. It is practically insoluble in water, freely soluble in dimethyl sulfoxide and dimethylformamide, and slightly soluble in methanol and 95% ethanol.
FLOVENT 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, FLOVENT DISKUS delivers 46, 94, and 229 mcg of fluticasone propionate from FLOVENT DISKUS 50 mcg, FLOVENT DISKUS 100 mcg, and FLOVENT 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 FEV1 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 FLOVENT DISKUS was 70 and 104 L/min, respectively (range: 48 to 123 L/min).
Asthma is a chronic lung disorder that can make breathing difficult. It features narrow, inflamed airways (bronchial tubes). “Asthma” is an ancient Greek word meaning “short breath,” and as the name implies, it can leave you gasping for air. One of the telltale signs of an asthma attacks is wheezing with difficulty breathing. Other asthma symptoms include chest tightness, coughing, and shortness of breath.
When the breathing tubes of the lungs become chronically inflamed, they can become sensitive to inhaled environmental allergens and irritants that can trigger asthma. These environmental triggers include pollen, pollution, and tobacco smoke. Exercise can also be an asthma trigger for some.
