Fluticasone Propionate HFA

1 INDICATIONS AND USAGE Fluticasone Propionate HFA 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 HFA is not indicated for the relief of acute bronchospasm. Fluticasone Propionate HFA 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 HFA 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 HFA to young patients. Priming 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. 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.

5 WARNINGS AND PRECAUTIONS • Candida albicans infection of the mouth and pharynx may occur. Monitor patients periodically. Advise the patient to rinse his/her mouth with water without swallowing after inhalation to help reduce the risk. ( 5.1 ) • Potential worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infections; ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients. ( 5.3 ) • Risk of impaired adrenal function when transferring from systemic corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to Fluticasone Propionate HFA. ( 5.4 ) • Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue Fluticasone Propionate HFA slowly. ( 5.5 ) • Assess for decrease in bone mineral density initially and periodically thereafter. ( 5.7 ) • Monitor growth of pediatric patients. ( 5.8 ) • Glaucoma and cataracts may occur with long-term use of an inhaled corticosteroid (ICS). Consider referral to an ophthalmologist in patients who develop ocular symptoms or use Fluticasone Propionate HFA long term. ( 5.9 ) 5.1 Oropharyngeal Candidiasis In clinical trials, the development of localized infections of the mouth and pharynx with Candida albicans has occurred in subjects treated with fluticasone propionate HFA. When such an infection develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while treatment with Fluticasone Propionate HFA continues, but at times therapy with Fluticasone Propionate HFA may need to be interrupted. Advise the patient to rinse his/her mouth with water without swallowing following inhalation to help reduce the risk of oropharyngeal candidiasis. 5.2 Acute Asthma Episodes Fluticasone Propionate HFA is not to be regarded as a bronchodilator and is not indicated for rapid relief of bronchospasm. Patients should be instructed to contact their physicians immediately when episodes of asthma that are not responsive to bronchodilators occur during the course of treatment with Fluticasone Propionate HFA. During such episodes, patients may require therapy with oral corticosteroids. 5.3 Immunosuppression and Risk of Infections Persons who are using drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chickenpox and measles, for example, can have a more serious or even fatal course in susceptible children or adults using corticosteroids. In such children or adults who have not had these diseases or been properly immunized, particular care should be taken to avoid exposure. How the dose, route, and duration of corticosteroid administration affect the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If a patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If a patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. (See the respective package inserts for complete VZIG and IG prescribing information.) If chickenpox develops, treatment with antiviral agents may be considered. ICS should be used with caution, if at all, in patients with active or quiescent tuberculosis infections of the respiratory tract; systemic fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. 5.4 Transferring Patients from Systemic Corticosteroid Therapy Hypothalamic-Pituitary-Adrenal Suppression/Adrenal Insufficiency Particular care is needed for patients who have been transferred from systemically active corticosteroids to ICS because deaths due to adrenal insufficiency have occurred in patients with asthma during and after transfer from sys…

4 CONTRAINDICATIONS Fluticasone Propionate HFA is contraindicated in the following conditions: • Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required [see Warnings and Precautions ( 5.2 )] . • Hypersensitivity to any of the ingredients [see Warnings and Precautions ( 5.6 ), Adverse Reactions ( 6.2 ), Description ( 11 )] . • Primary treatment of status asthmaticus or acute episodes of asthma requiring intensive measures.

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 HFA 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.

8.1 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 approximately 0.001 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.08 mcg/kg/day). Flu…
