Uses
FLOVENT® DISKUS® is indicated for the maintenance treatment of asthma as prophylactic therapy in patients aged 4 years and older. It is also indicated for patients requiring oral corticosteroid therapy for asthma. Many of these patients may be able to reduce or eliminate their requirement for oral corticosteroids over time.
Important Limitation of Use: FLOVENT DISKUS is NOT indicated for the relief of acute bronchospasm.

Other Information
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-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 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).
The actual amount of drug delivered to the lung will depend on patient factors, such as inspiratory flow profile.

Flovent DISKUS should be administered by the orally inhaled route only in patients aged 4 years and older. After inhalation, the patient should rinse his/her mouth with water without swallowing to help reduce the risk of oropharyngeal candidiasis.
Individual patients will experience a variable time to onset and degree of symptom relief. Maximum benefit may not be achieved for 1 to 2 weeks or longer after starting treatment.
After asthma stability has been achieved, it is always desirable to titrate to the lowest effective dosage to reduce the possibility of side effects. For patients who do not respond adequately to the starting dosage after 2 weeks of therapy, higher dosages may provide additional asthma control. The safety and efficacy of FLOVENT DISKUS when administered in excess of recommended dosages have not been established.
The recommended starting dosage and the highest recommended dosage of FLOVENT DISKUS, based on prior asthma therapy, are listed in Table 1.
Table 1. Recommended Dosages of FLOVENT DISKUS
NOTE: In all patients, it is desirable to titrate to the lowest effective dosage once asthma stability is achieved.
Previous Therapy
Recommended Starting Dosage
Highest Recommended Dosage
Adult and adolescent patients (aged 12 years and older)
Bronchodilators alone
100 mcg twice daily
500 mcg twice daily
Inhaled corticosteroids
100-250 mcg twice dailya
500 mcg twice daily
Oral corticosteroidsb
500-1,000 mcg twice dailyc
1,000 mcg twice daily
Pediatric patients (aged 4-11 years)d
50 mcg twice dailya
100 mcg twice daily
aStarting dosages above 100 mcg twice daily for adult and adolescent patients and 50 mcg twice daily for pediatric patients aged 4 to 11 years may be considered for patients with poorer asthma control or those who have previously required doses of inhaled corticosteroids that are in the higher range for the specific agent.
bFor patients currently receiving chronic oral corticosteroid therapy, prednisone should be reduced no faster than 2.5 to 5 mg/day on a weekly basis beginning after at least 1 week of therapy with FLOVENT DISKUS. Patients should be carefully monitored for signs of asthma instability, including serial objective measures of airflow, and for signs of adrenal insufficiency [see Warnings and Precautions (5.4)]. Once prednisone reduction is complete, the dosage of FLOVENT DISKUS should be reduced to the lowest effective dosage.
cThe choice of starting dosage should be made on the basis of individual patient assessment. A controlled clinical trial of 111 oral corticosteroid-dependent subjects with asthma showed few significant differences between the 2 doses of FLOVENT DISKUS on safety and efficacy endpoints. However, inability to decrease the dose of oral corticosteroids further during corticosteroid reduction may be indicative of the need to increase the dose of fluticasone propionate up to the maximum of 1,000 mcg twice daily.
dBecause individual responses may vary, pediatric patients previously maintained on other inhaled corticosteroids may require dosage adjustments upon transfer to FLOVENT DISKUS.
