fluticasone propionate

1 INDICATIONS AND USAGE Fluticasone propionate inhalation aerosol is indicated for the maintenance treatment of asthma as prophylactic therapy in adult and pediatric patients aged 4 years and older. Limitations of Use Fluticasone propionate inhalation aerosol is not indicated for the relief of acute bronchospasm. Fluticasone propionate inhalation aerosol is an inhaled corticosteroid indicated for: • Maintenance treatment of asthma as prophylactic therapy in adult and pediatric patients aged 4 years and older. ( 1 ) Limitations of use: Not indicated for relief of acute bronchospasm. ( 1 )

2 DOSAGE AND ADMINISTRATION • For oral inhalation only. ( 2.1 ) • Starting dosage is based on prior asthma therapy and disease severity. ( 2.2 ) • Adult and adolescent patients aged 12 years and older: 88 mcg twice daily up to a maximum dosage of 880 mcg twice daily. ( 2.2 ) • Pediatric patients aged 4 to 11 years: 88 mcg twice daily. ( 2.2 ) 2.1 Administration Information Fluticasone propionate inhalation aerosol should be administered by the orally inhaled route only. After inhalation, rinse mouth with water without swallowing to help reduce the risk of oropharyngeal candidiasis. A valved holding chamber and mask may be used to deliver Fluticasone propionate inhalation aerosol to young patients. Priming Prime fluticasone propionate inhalation aerosol before using for the first time by releasing 4 sprays into the air away from the face, shaking well for 5 seconds before each spray. In cases where the inhaler has not been used for more than 7 days or when it has been dropped, prime the inhaler again by shaking well for 5 seconds and releasing 1 spray into the air away from the face. Avoid spraying in eyes. 2.2 Recommended Dosage Adult and Adolescent Patients Aged 12 Years and Older The recommended starting dosage for patients aged 12 years and older who are not on an inhaled corticosteroid (ICS): 88 mcg (2 inhalations of 44 mcg fluticasone propionate) twice daily by oral inhalation, approximately 12 hours apart. • The maximum recommended dosage for patients aged 12 years and older is 880 mcg twice daily. Pediatric Patients Aged 4 to 11 Years The recommended dosage for patients aged 4 to 11 years: 88 mcg (2 inhalations of 44 mcg fluticasone propionate) twice daily by oral inhalation, approximately 12 hours apart. General Dosing Recommendations The starting dosage is based on previous asthma therapy and asthma severity, including consideration of patients’ current control of asthma symptoms and risk of future exacerbation. If symptoms arise between doses, an inhaled short-acting beta 2 -agonist should be used for immediate relief. 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. For other patients, and for patients who do not respond adequately to the starting dosage after 2 weeks of therapy, higher dosages may provide additional asthma control. If a dosage regimen fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options, e.g., replacing the current strength with a higher strength, initiating an ICS and long-acting beta 2 -agonist (LABA) combination product, or initiating oral corticosteroids, should be considered. After asthma stability has been achieved, titrate to the lowest effective dosage to reduce the possibility of side effects.

7 DRUG INTERACTIONS Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid effects. ( 7.1 ) 7.1 Inhibitors of Cytochrome P450 3A4 Fluticasone propionate is a substrate of CYP3A4. The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with fluticasone propionate inhalation aerosol is not recommended because increased systemic corticosteroid adverse effects may occur. Ritonavir A drug interaction trial with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a strong CYP3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] . During postmarketing use, there have been reports of clinically significant drug interactions in patients receiving fluticasone propionate and ritonavir, resulting in systemic corticosteroid effects including Cushing’s syndrome and adrenal suppression. Ketoconazole Coadministration of orally inhaled fluticasone propionate (1,000 mcg) and ketoconazole (200 mg once daily) resulted in a 1.9-fold increase in plasma fluticasone propionate exposure and a 45% decrease in plasma cortisol area under the curve (AUC), but had no effect on urinary excretion of cortisol.

8 USE IN SPECIFIC POPULATIONS Hepatic impairment: Monitor patients for signs of increased drug exposure. ( 8.6 ) 8.1 Pregnancy Risk Summary There are insufficient data on the use of fluticasone propionate HFA in pregnant women. There are clinical considerations with the use of fluticasone propionate HFA in pregnant women. (See Clinical Considerations.) In animals, teratogenicity characteristic of corticosteroids, decreased fetal body weight and/or skeletal variations in rats, mice, and rabbits, was observed with subcutaneously administered maternal toxic doses of fluticasone propionate less than the maximum recommended human daily inhaled dose (MRHDID) on a mcg/m 2 basis. (See Data.) However, fluticasone propionate administered via inhalation to rats decreased fetal body weight but did not induce teratogenicity at a maternal toxic dose less than the MRHDID on a mcg/m 2 basis. (See Data.) Experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroids than humans. The estimated risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryofetal Risk: In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal outcomes such as pre-eclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control. Data Human Data: Following inhaled administration, fluticasone propionate was detected in the neonatal cord blood after delivery. Animal Data: In embryofetal development studies with pregnant rats and mice dosed by the subcutaneous route throughout the period of organogenesis, fluticasone propionate was teratogenic in both species. Omphalocele, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, at a dose approximately 0.5 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 100 mcg/kg/day). The rat no observed adverse effect level (NOAEL) was observed at approximately 0.17 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 30 mcg/kg/day). Cleft palate and fetal skeletal variations were observed in mouse fetuses at a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 45 mcg/kg/day). The mouse NOAEL was observed with a dose approximately 0.04 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 15 mcg/kg/day). In an embryofetal development study with pregnant rats dosed by the inhalation route throughout the period of organogenesis, fluticasone propionate produced decreased fetal body weights and skeletal variations, in the presence of maternal toxicity, at a dose approximately 0.14 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 25.7 mcg/kg/day); however, there was no evidence of teratogenicity. The NOAEL was observed with a dose approximately 0.03 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 5.5 mcg/kg/day). In an embryofetal development study in pregnant rabbits that were dosed by the subcutaneous route throughout organogenesis, fluticasone propionate produced reductions of fetal body weights, in the presence of maternal toxicity, at doses approximately 0.006 times the MRHDID and higher (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.57 mcg/kg/day). Teratogenicity was evident based upon a finding of cleft palate for 1 fetus at a dose approximately 0.04 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 4 mcg/kg/day). The NOAEL was observed in rabbit fetuses with a dose ap …

12.1 Mechanism of Action Fluticasone propionate is a synthetic trifluorinated corticosteroid with anti-inflammatory activity. Fluticasone propionate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor that is 18 times that of dexamethasone, almost twice that of beclomethasone‐17‐monopropionate (BMP), the active metabolite of beclomethasone dipropionate, and over 3 times that of budesonide. Data from the McKenzie vasoconstrictor assay in man are consistent with these results. The clinical significance of these findings is unknown. Inflammation is an important component in the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation. These anti-inflammatory actions of corticosteroids contribute to their efficacy in asthma. Though effective for the treatment of asthma, corticosteroids do not affect asthma symptoms immediately. 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. When corticosteroids are discontinued, asthma stability may persist for several days or longer. Trials in subjects with asthma have shown a favorable ratio between topical anti-inflammatory activity and systemic corticosteroid effects with recommended doses of orally inhaled fluticasone propionate. This is explained by a combination of a relatively high local anti-inflammatory effect, negligible oral systemic bioavailability (<1%), and the minimal pharmacological activity of the only metabolite detected in man.

11 DESCRIPTION Fluticasone Propionate HFA is a pressurized metered dose inhaler for oral inhalation. The active component of Fluticasone Propionate HFA 44 mcg, Fluticasone Propionate HFA 110 mcg, and Fluticasone Propionate HFA 220 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 HFA is a dark orange plastic inhaler with a peach cap containing a pressurized metered-dose aerosol canister fitted with a counter. Each canister contains a microcrystalline suspension of micronized fluticasone propionate in propellant HFA-134a (1,1,1,2-tetrafluoroethane). It contains no other excipients. After priming, each actuation of the inhaler delivers 50, 125, or 250 mcg of fluticasone propionate in 60 mg of suspension (for the 44-mcg product) or in 75 mg of suspension (for the 110- and 220-mcg products) from the valve. Each actuation delivers 44, 110, or 220 mcg of fluticasone propionate from the actuator. The actual amount of drug delivered to the lung will depend on patient factors, such as the coordination between the actuation of the inhaler and inspiration through the delivery system. Prime Fluticasone Propionate HFA before using for the first time by releasing 4 sprays into the air away from the face, shaking well for 5 seconds before each spray. In cases where the inhaler has not been used for more than 7 days or when it has been dropped, prime the inhaler again by shaking well for 5 seconds and releasing 1 spray into the air away from the face. Avoid spraying in eyes. Fluticasone propionate chemical structure
