Why two NDCs? The FDA registers this code as 50090-4504-0 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 50090-4504-00. Same drug, same package — only the format differs.

1 inactive ingredient listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Advair HFA — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Advair HFA. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 50090-4504-0, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 50090-4504-00, written without dashes as 50090450400. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 50090-4504-00, the first segment (50090) is the labeler code FDA assigned to A-S Medication Solutions; the middle segment (4504) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (00) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by A-S Medication Solutions. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
A-S Medication Solutions is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?

🎯 Indications and Usage 127 words ▾

1 INDICATIONS AND USAGE ADVAIR HFA is indicated for treatment of asthma in adult and adolescent patients aged 12 years and older. ADVAIR HFA should be used for patients not adequately controlled on a long-term asthma control medication such as an inhaled corticosteroid (ICS) or whose disease warrants initiation of treatment with both an ICS and long-acting beta 2 -adrenergic agonist (LABA). Limitations of Use ADVAIR HFA is not indicated for the relief of acute bronchospasm.

ADVAIR HFA is a combination of fluticasone propionate, an inhaled corticosteroid, and salmeterol, a long-acting beta 2 ‑adrenergic agonist (LABA), indicated for treatment of asthma in adult and adolescent patients aged 12 years and older. ( 1 ) Limitations of use: Not indicated for relief of acute bronchospasm. ( 1 )

⏱️ Dosage and Administration ~2 min read ▾

2 DOSAGE AND ADMINISTRATION • For oral inhalation only. ( 2.1 ) • Adult and adolescent patients aged 12 years and older: 2 inhalations of ADVAIR HFA 45 mcg/21 mcg, ADVAIR HFA 115 mcg/21 mcg, or ADVAIR HFA 230 mcg/21 mcg twice daily. ( 2.2 ) • Starting dosage is based on asthma severity. ( 2.2 )

2.1Administration Information ADVAIR 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. Priming Prime ADVAIR 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 4 weeks or when it has been dropped, prime the inhaler again by releasing 2 sprays into the air away from the face, shaking well for 5 seconds before each spray. Avoid spraying in eyes.

2.2Recommended Dosage Adult and adolescent patients aged 12 years and older: 2 oral inhalations twice daily, approximately 12 hours apart. The maximum recommended dosage is 2 inhalations of ADVAIR HFA 230 mcg/21 mcg twice daily. General Dosing Recommendation When choosing the starting dosage strength of ADVAIR HFA, consider the patients’ disease severity, based on their previous asthma therapy, including the ICS dosage, as well as the patients’ current control of asthma symptoms and risk of future exacerbation.

If asthma symptoms arise in the period between doses, an inhaled, short-acting beta 2 -agonist should be used for immediate relief. Improvement in asthma control following inhaled administration of ADVAIR HFA can occur within 30 minutes of beginning treatment, although maximum benefit may not be achieved for 1 week or longer after starting treatment. Individual patients will experience a variable time to onset and degree of symptom relief.

For patients who do not respond adequately to the starting dosage after 2 weeks of therapy, replacing the current strength of ADVAIR HFA with a higher strength may provide additional improvement in asthma control. If a previously effective dosage regimen fails to provide adequate improvement in asthma control, the therapeutic regimen should be reevaluated and additional therapeutic options (e.g., replacing the current strength of ADVAIR HFA with a higher strength, adding additional ICS, initiating oral corticosteroids) should be considered.

More frequent administration or a greater number of inhalations (more than 2 inhalations twice daily) of the prescribed strength of ADVAIR HFA is not recommended as some patients are more likely to experience adverse effects with higher doses of salmeterol. Patients using ADVAIR HFA should not use additional LABA for any reason. [See Warnings and Precautions ( 5.3 , 5.12 ).]

💊 Dosage Forms and Strengths 100 words ▾

3 DOSAGE FORMS AND STRENGTHS Inhalation aerosol: purple plastic inhaler with a light purple cap containing a pressurized metered-dose aerosol canister containing 60 or 120 metered inhalations and fitted with a counter. • 45 mcg fluticasone propionate/21 mcg salmeterol from the mouthpiece per actuation • 115 mcg fluticasone propionate/21 mcg salmeterol from the mouthpiece per actuation • 230 mcg fluticasone propionate/21 mcg salmeterol from the mouthpiece per actuation Inhalation aerosol: • 45 mcg fluticasone propionate/21 mcg salmeterol per actuation (3) • 115 mcg fluticasone propionate/21 mcg salmeterol per actuation (3) • 230 mcg fluticasone propionate/21 mcg salmeterol per actuation (3)

⛔ Contraindications 82 words ▾

4 CONTRAINDICATIONS ADVAIR 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 ( 5.11 ), Adverse Reactions ( 6.2 ), Description ( 11 )] . • Primary treatment of status asthmaticus or acute episodes of asthma requiring intensive measures. ( 4 ) • Hypersensitivity to any ingredient. (4)

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • LABA monotherapy increases the risk of serious asthma-related events. (5.1) • Do not initiate in acutely deteriorating asthma or to treat acute symptoms. (5.2) • Do not use in combination with an additional medicine containing a LABA because of risk of overdose.

(5.3) • 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.

( 5.4 ) • Increased risk of pneumonia in patients with COPD. Monitor patients for signs and symptoms of pneumonia. ( 5.5 ) • 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. ( 5.6 ) • Risk of impaired adrenal function when transferring from systemic corticosteroids.

Taper patients slowly from systemic corticosteroids if transferring to ADVAIR HFA. ( 5.7 ) • Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue ADVAIR HFA slowly.

( 5.8 ) • If paradoxical bronchospasm occurs, discontinue ADVAIR HFA and institute alternative therapy. ( 5.10 ) • Use with caution in patients with cardiovascular or central nervous system disorders because of beta-adrenergic stimulation. ( 5.12 ) • Assess for decrease in bone mineral density initially and periodically thereafter.

( 5.13 ) • Monitor growth of pediatric patients. ( 5.14 ) • Glaucoma and cataracts may occur with long-term use of inhaled corticosteroids. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use ADVAIR HFA long term.

( 5.15 ) • Be alert to eosinophilic conditions, hypokalemia, and hyperglycemia. ( 5.16 , 5.18 ) • Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis. ( 5.17 )

5.1Serious Asthma-Related Events – Hospitalizations, Intubations, Death Use of LABA as monotherapy (without ICS) for asthma is associated with an increased risk of asthma-related death [see Salmeterol Multicenter Asthma Research Trial (SMART)] . Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. These findings are considered a class effect of LABA monotherapy.

When LABA are used in fixed-dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone (see Serious Asthma-Related Events with Inhaled Corticosteroid/Long-acting Beta 2 -adrenergic Agonists) . Serious Asthma-Related Events with Inhaled Corticosteroid/Long-acting Beta 2 -adrenergic Agonists Four (4) large, 26-week, randomized, double-blind, active-controlled clinical safety trials were conducted to evaluate the risk of serious asthma-related events when LABA were used in fixed‑dose combination with ICS compared with ICS alone in subjects with asthma.

Three (3) trials included adult and adolescent subjects aged 12 years and older: 1 trial compared fluticasone propionate/salmeterol inhalation powder with fluticasone propionate inhalation powder, 1 trial compared mometasone furoate/formoterol with mometasone furoate, and 1 trial compared budesonide/formoterol with budesonide. The fourth trial included pediatric subjects aged 4 to 11 years and compared fluticasone propionate/salmeterol inhalation powder with fluticasone propionate inhalation powder. The primary safety endpoint for all 4 trials was serious asthma-related events (hospitalizations, intubations, death).

A blinded adjudication committee determined whether events were asthma related. The 3 adult and ado…

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Serious asthma-related events – hospitalizations, intubations, death [see Warnings and Precautions (5.1)] • Oropharyngeal candidiasis [see Warnings and Precautions (5.4)] • Pneumonia in patients with COPD [see Warnings and Precautions (5.5)] • Immunosuppression and risk of infections [see Warnings and Precautions (5.6)] • Hypercorticism and adrenal suppression [see Warnings and Precautions (5.8)] • Cardiovascular and central nervous system effects [see Warnings and Precautions (5.12)] • Reduction in bone mineral density [see Warnings and Precautions (5.13)] • Growth effects [see Warnings and Precautions (5.14)] • Glaucoma and cataracts [see Warnings and Precautions (5.15)] Most common adverse reactions (incidence ≥3%) include: upper respiratory tract infection or inflammation, throat irritation, dysphonia, headache, dizziness, nausea and vomiting.

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact GlaxoSmithKline at 1-888-825-5249 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult and Adolescent Subjects Aged 12 Years and Older The incidence of adverse reactions associated with ADVAIR HFA in Table 2 is based upon two 12-week, placebo-controlled, U.S. clinical trials (Trials 1 and 3) and 1 active-controlled 12-week U.S. clinical trial (Trial 2).

A total of 1,008 adult and adolescent subjects with asthma (556 females and 452 males) previously treated with albuterol alone, salmeterol, or ICS were treated twice daily with 2 inhalations of ADVAIR HFA 45 mcg/21 mcg or ADVAIR HFA 115 mcg/21 mcg, fluticasone propionate CFC inhalation aerosol (44- or 110-mcg doses), salmeterol CFC inhalation aerosol 21 mcg, or placebo HFA inhalation aerosol. The average duration of exposure was 71 to 81 days in the active treatment groups compared with 51 days in the placebo group.

🔄 Drug Interactions ~2 min read ▾

7 DRUG INTERACTIONS ADVAIR HFA has been used concomitantly with other drugs, including short-acting beta 2 -agonists, methylxanthines, and nasal corticosteroids, commonly used in patients with asthma without adverse drug reactions [see Clinical Pharmacology (12.2)] . No formal drug interaction trials have been performed with ADVAIR HFA. • Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid and cardiovascular effects.

( 7.1 ) • Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of salmeterol on vascular system. ( 7.2 ) • Beta-blockers: Use with caution.

May block bronchodilatory effects of beta-agonists and produce severe bronchospasm. ( 7.3 ) • Diuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non–potassium-sparing diuretics may worsen with concomitant beta-agonists.

( 7.4 )

7.1Inhibitors of Cytochrome P450 3A4 Fluticasone propionate and salmeterol, the individual components of ADVAIR HFA, are substrates of CYP3A4. The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with ADVAIR HFA is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur. Ritonavir Fluticasone Propionate: 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 Fluticasone Propionate: 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.

Salmeterol: In a drug interaction trial in 20 healthy subjects, coadministration of inhaled salmeterol (50 mcg twice daily) and oral ketoconazole (400 mg once daily) for 7 days resulted in greater systemic exposure to salmeterol (AUC increased 16-fold and C max increased 1.4-fold). Three (3) subjects were withdrawn due to beta 2 -agonist side effects (2 with prolonged QTc and 1 with palpitations and sinus tachycardia). Although there was no statistical effect on the mean QTc, coadministration of salmeterol and ketoconazole was associated with more frequent increases in QTc duration compared with salmeterol and placebo administration.

7.2Monoamine Oxidase Inhibitors and Tricyclic Antidepressants ADVAIR HFA should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of salmeterol, a component of ADVAIR HFA, on the vascular system may be potentiated by these agents.

7.3Beta-adrenergic Receptor Blocking Agents Beta-blockers not only block the pulmonary effect of beta-agonists, such as salmeterol, a component of ADVAIR HFA, but may also produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents for these patients; cardioselective beta-blockers could be considered, although they should be administered with caution.

8.1Pregnancy Risk Summary There are insufficient data on the use of ADVAIR HFA or individual monoproducts, fluticasone propionate and salmeterol xinafoate, in pregnant women. There are clinical considerations with the use of ADVAIR 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. Oral administration of salmeterol to pregnant rabbits caused teratogenicity characteristic of beta-adrenoceptor stimulation at maternal doses approximately 25 times the MRHDID on an AUC basis.

These adverse effects generally occurred at large multiples of the MRHDID when salmeterol was administered by the oral route to achieve high systemic exposures. No such effects occurred at an oral salmeterol dose approximately 10 times the MRHDID. (See Data.) 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 should be closely monitored and medication adjusted as necessary to maintain optimal control of asthma.

Labor and Delivery: There are no human studies evaluating the effects of ADVAIR HFA during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of ADVAIR HFA during labor should be restricted to those patients in whom the benefits clearly outweigh the risks. Data Human Data: Fluticasone Propionate: Following inhaled administration, fluticasone propionate was detected in the neonatal cord blood after delivery.

Animal Data: Fluticasone Propionate and Salmeterol: In an embryofetal development study with pregnant rats that received the combination of subcutaneous administration of fluticasone propionate and oral administration of salmeterol at doses of 0/1,000; 30/0; 10/100; 30/1,000; and 100/10,000 mcg/kg/day (as fluticasone propionate/salmeterol) during the period of organogenesis, findings were generally consistent with the individual monoproducts and there was no exacerbation of expected fetal effects. Omphalocele, increased embryofetal deaths, decreased body weight, and skeletal variations were observed in rat fetuses in the presence of maternal toxicity when combining fluticasone propionate at a dose approximately equivalent to the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 100 mcg/kg/day) and salmeterol at a dose approximately 1,200 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day).

The rat no observed adverse effect level (NOAEL) was observed when combining fluticasone propionate at a dose less than the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 30 mcg/kg/day) and salmeterol at a dose approximately 120 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 1,000 mcg/kg/day).

🧒 Pediatric Use ~3 min read ▾

8.4Pediatric Use The safety and effectiveness of ADVAIR HFA have been established in pediatric patients aged 12 years and older. Use of ADVAIR HFA in this age group is supported by evidence from adequate and well-controlled studies in adults with additional data from thirty-eight (38) subjects aged 12 to 17 years were treated with ADVAIR HFA in U.S. pivotal clinical trials. Subjects in this age group demonstrated efficacy results similar to those observed in subjects aged 18 years and older.

There were no obvious differences in the type or frequency of adverse events reported in this age group compared with subjects aged 18 years and older. In a 12-week trial, the safety of ADVAIR HFA 45 mcg/21 mcg given as 2 inhalations twice daily was compared with that of fluticasone propionate 44 mcg HFA (FLOVENT HFA) 2 inhalations twice daily in 350 subjects aged 4 to 11 years with persistent asthma currently being treated with ICS. No new safety concerns were observed in children aged 4 to 11 years treated for 12 weeks with ADVAIR HFA 45 mcg/21 mcg compared with adults and adolescents aged 12 years and older.

Common adverse reactions (≥3%) seen in children aged 4 to 11 years treated with ADVAIR HFA 45 mcg/21 mcg but not reported in the adult and adolescent clinical trials of ADVAIR HFA include: pyrexia, cough, pharyngolaryngeal pain, rhinitis, and sinusitis [see Adverse Reactions (6.1)] . This trial was not designed to assess the effect of salmeterol, a component of ADVAIR HFA, on asthma hospitalizations and death in subjects aged 4 to 11 years. The pharmacokinetics and pharmacodynamic effect on serum cortisol of 21 days of treatment with ADVAIR HFA 45 mcg/21 mcg (2 inhalations twice daily with or without a spacer) or ADVAIR DISKUS 100 mcg/50 mcg (1 inhalation twice daily) was evaluated in a trial of 31 children aged 4 to 11 years with mild asthma.

Systemic exposure to salmeterol xinafoate was similar for ADVAIR HFA, ADVAIR HFA delivered with a spacer, and ADVAIR DISKUS while the systemic exposure to fluticasone propionate was lower with ADVAIR HFA compared with that of ADVAIR HFA delivered with a spacer or ADVAIR DISKUS. There were reductions in serum cortisol from baseline in all treatment groups (14%, 22%, and 13% for ADVAIR HFA, ADVAIR HFA delivered with a spacer, and ADVAIR DISKUS, respectively) [see Clinical Pharmacology (12.2, 12.3)] . The safety and effectiveness of ADVAIR HFA in pediatric patients younger than 12 years have not been established.

Effects on Growth ICS, including fluticasone propionate, a component of ADVAIR HFA, may cause a reduction in growth velocity in children and adolescents [see Warnings and Precautions (5.14)] . The growth of pediatric patients receiving orally inhaled corticosteroids, including ADVAIR HFA, should be monitored. A 52-week placebo-controlled trial to assess the potential growth effects of fluticasone propionate inhalation powder (FLOVENT ROTADISK) at 50 and 100 mcg twice daily was conducted in the U.S. in 325 prepubescent children (244 males and 81 females) aged 4 to 11 years.

The mean growth velocities at 52 weeks observed in the intent-to-treat population were 6.32 cm/year in the placebo group (n = 76), 6.07 cm/year in the 50-mcg group (n = 98), and 5.66 cm/year in the 100-mcg group (n = 89). An imbalance in the proportion of children entering puberty between groups and a higher dropout rate in the placebo group due to poorly controlled asthma may be confounding factors in interpreting these data. A separate subset analysis of children who remained prepubertal during the trial revealed growth rates at 52 weeks of 6.10 cm/year in the placebo group (n = 57), 5.91 cm/year in the 50-mcg group (n = 74), and 5.67 cm/year in the 100-mcg group (n = 79).

In children aged 8.5 years, the mean age of children in this trial, the range for expected growth velocity is: boys – 3 rd percentile = 3.8 cm/year, 50 th percentile = 5.4 cm/year, and 97 th percentile = 7.0 cm/year; girls – 3 rd percentile = 4.2…

🧓 Geriatric Use 106 words ▾

8.5Geriatric Use Clinical trials of ADVAIR HFA did not include sufficient numbers of subjects aged 65 years and older to determine whether older subjects respond differently than younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. In addition, as with other products containing beta 2 -agonists, special caution should be observed when using ADVAIR HFA in geriatric patients who have concomitant cardiovascular disease that could be adversely affected by beta 2 -agonists.

🆘 Overdosage 199 words ▾

10 OVERDOSAGE No human overdosage data has been reported for ADVAIR HFA. ADVAIR HFA contains both fluticasone propionate and salmeterol; therefore, the risks associated with overdosage for the individual components described below apply to ADVAIR HFA. Treatment of overdosage consists of discontinuation of ADVAIR HFA together with institution of appropriate symptomatic and/or supportive therapy.

The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. Cardiac monitoring is recommended in cases of overdosage. Fluticasone Propionate Chronic overdosage of fluticasone propionate may result in signs/symptoms of hypercorticism [see Warnings and Precautions (5.8)] .

Salmeterol The expected signs and symptoms with overdosage of salmeterol are those of excessive beta‑adrenergic stimulation and/or occurrence or exaggeration of any of the signs and symptoms of beta-adrenergic stimulation (e.g., seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats/min, arrhythmias, nervousness, headache, tremor, muscle cramps, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, hyperglycemia, hypokalemia, metabolic acidosis). Overdosage with salmeterol can lead to clinically significant prolongation of the QTc interval, which can produce ventricular arrhythmias.

As with all inhaled sympathomimetic medicines, cardiac arrest and even death may be associated with an overdose of salmeterol.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action ADVAIR HFA ADVAIR HFA contains both fluticasone propionate and salmeterol. The mechanisms of action described below for the individual components apply to ADVAIR HFA. These drugs represent 2 different classes of medications (a synthetic corticosteroid and a LABA) that have different effects on clinical, physiologic, and inflammatory indices of asthma.

Fluticasone Propionate 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. Salmeterol Xinafoate Salmeterol is a selective LABA. In vitro studies show salmeterol to be at least 50 times more selective for beta 2 ‑adrenoceptors than albuterol.

Although beta 2 -adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 -adrenoceptors are the predominant receptors in the heart, there are also beta 2 -adrenoceptors in the human heart comprising 10% to 50% of the total beta-adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta 2 -agonists may have cardiac effects. The pharmacologic effects of beta 2 -adrenoceptor agonist drugs, including salmeterol, are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3′,5′-adenosine monophosphate (cyclic AMP).

Increased cyclic AMP levels cause relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells. In vitro tests show that salmeterol is a potent and long-lasting inhibitor of the release of mast cell mediators, such as histamine, leukotrienes, and prostaglandin D 2 , from human lung. Salmeterol inhibits histamine-induced plasma protein extravasation and inhibits platelet-activating factor–induced eosinophil accumulation in the lungs of guinea pigs when administered by the inhaled route.

In humans, single doses of salmeterol administered via inhalation aerosol attenuate allergen-induced bronchial hyper-responsiveness.

12.2Pharmacodynamics ADVAIR HFA Healthy Subjects: Cardiovascular Effects: Since systemic pharmacodynamic effects of salmeterol are not normally seen at the therapeutic dose, higher doses were used to produce measurable effects. Four (4) placebo-controlled crossover trials were conducted with healthy subjects: (1) a cumulative-dose trial using 42 to 336 mcg of salmeterol CFC inhalation aerosol given alone or as ADVAIR HFA 115 mcg/21 mcg, (2) a single-dose trial using 4 inhalations of ADVAIR HFA 230 mcg/21 mcg, salmeterol CFC inhalation aerosol 21 mcg, or fluticasone propionate CFC inhalation aerosol 220 mcg, (3) a single-dose trial using 8 inhalations of ADVAIR HFA 45 mcg/21 mcg, ADVAIR HFA 115 mcg/21 mcg, or ADVAIR HFA 230 mcg/21 mcg, and (4) a single-dose trial using 4 inhalations of ADVAIR HFA 230 mcg/21 mcg; 2 inhalations of ADVAIR DISKUS 500 mcg/50 mcg; 4 inhalations of fluticasone propionate CFC inhalation aerosol 220 mcg; or 1,010 mcg of fluticasone propionate gi…

📋 Description ~2 min read ▾

11 DESCRIPTION ADVAIR HFA 45 mcg/21 mcg, ADVAIR HFA 115 mcg/21 mcg, and ADVAIR HFA 230 mcg/21 mcg are combinations of fluticasone propionate and salmeterol xinafoate. One active component of ADVAIR HFA 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. The other active component of ADVAIR HFA is salmeterol xinafoate, a beta 2 -adrenergic bronchodilator. Salmeterol xinafoate is the racemic form of the 1-hydroxy-2-naphthoic acid salt of salmeterol.

It has the chemical name 4-hydroxy-α 1 -[[[6-(4-phenylbutoxy)hexyl]amino]methyl]-1,3-benzenedimethanol, 1-hydroxy-2-naphthalenecarboxylate and the following chemical structure: Salmeterol xinafoate is a white powder with a molecular weight of 603.8, and the empirical formula is C 25 H 37 NO 4 •C 11 H 8 O 3 . It is freely soluble in methanol; slightly soluble in ethanol, chloroform, and isopropanol; and sparingly soluble in water. ADVAIR HFA is a purple plastic inhaler with a light purple cap containing a pressurized metered-dose aerosol canister fitted with a counter.

Each canister contains a microcrystalline suspension of micronized fluticasone propionate and micronized salmeterol xinafoate 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 and 25 mcg of salmeterol in 75 mg of suspension from the valve.

Each actuation delivers 45, 115, or 230 mcg of fluticasone propionate and 21 mcg of salmeterol from the actuator. Twenty-one micrograms (21 mcg) of salmeterol base is equivalent to 30.45 mcg of salmeterol xinafoate. 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 ADVAIR 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 4 weeks or when it has been dropped, prime the inhaler again by releasing 2 sprays into the air away from the face, shaking well for 5 seconds before each spray. Avoid spraying in eyes.

💬 Information for Patients ~3 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Serious Asthma-Related Events Inform patients with asthma that LABA when used alone increases the risk of asthma-related hospitalization or asthma-related death. Available data show that when ICS and LABA are used together, such as with ADVAIR HFA, there is not a significant increase in the risk of these events. [See Warnings and Precautions (5.1).] Not for Acute Symptoms Inform patients that ADVAIR HFA is not meant to relieve acute asthma symptoms and extra doses should not be used for that purpose.

Advise patients to treat acute asthma symptoms with an inhaled, short-acting beta 2 -agonist such as albuterol. Provide patients with such medication and instruct them in how it should be used. Instruct patients to seek medical attention immediately if they experience any of the following: • Decreasing effectiveness of inhaled, short-acting beta 2 -agonists • Need for more inhalations than usual of inhaled, short-acting beta 2 -agonists • Significant decrease in lung function as outlined by the physician Tell patients they should not stop therapy with ADVAIR HFA without physician/provider guidance since symptoms may recur after discontinuation. [See Warnings and Precautions (5.2).] Do Not Use Additional Long-acting Beta 2 -agonists Instruct patients not to use other LABA for asthma. [See Warnings and Precautions (5.3).] Oropharyngeal Candidiasis Inform patients that localized infections with Candida albicans occurred in the mouth and pharynx in some patients.

If oropharyngeal candidiasis develops, treat it with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing therapy with ADVAIR HFA, but at times therapy with ADVAIR HFA may need to be temporarily interrupted under close medical supervision. Advise patients to rinse the mouth with water without swallowing after inhalation to help reduce the risk of thrush. [See Warnings and Precautions (5.4).] Pneumonia Patients with COPD have a higher risk of pneumonia; instruct them to contact their healthcare providers if they develop symptoms of pneumonia. [See Warnings and Precautions (5.5).] Immunosuppression and Risk of Infections Warn patients who are on immunosuppressant doses of corticosteroids to avoid exposure to chickenpox or measles and, if exposed, to consult their physicians without delay.

Inform patients of potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. [See Warnings and Precautions (5.6).] Hypercorticism and Adrenal Suppression Advise patients that ADVAIR HFA may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, inform patients that deaths due to adrenal insufficiency have occurred during and after transfer from systemic corticosteroids. Patients should taper slowly from systemic corticosteroids if transferring to ADVAIR HFA. [See Warnings and Precautions (5.8).] Hypersensitivity Reactions, including Anaphylaxis Advise patients that immediate hypersensitivity reactions (e.g., urticaria, angioedema, rash, bronchospasm, hypotension), including anaphylaxis, may occur after administration of ADVAIR HFA.

Patients should discontinue ADVAIR HFA if such reactions occur. [See Warnings and Precautions (5.11).] Risks Associated with Beta-agonist Therapy Inform patients of adverse effects associated with beta 2 -agonists, such as palpitations, chest pain, rapid heart rate, tremor, or nervousness. [See Warnings and Precautions (5.12).] Reduction in Bone Mineral Density Advise patients who are at an increased risk for decreased BMD that the use of corticosteroids may pose an additional risk. [See Warnings and Precautions (5.13).] Reduced Growth Velocity Inform patients that orally inhaled corticosteroids, including fluticasone propionate, may cause a reduction in growth velocity when administered to…

MEDICATION GUIDE ADVAIR ® [ ad′ vair ] HFA (fluticasone propionate and salmeterol) inhalation aerosol for oral inhalation What is the most important information I should know about ADVAIR HFA? ADVAIR HFA can cause serious side effects, including: • People with asthma who take long-acting beta 2 -adrenergic agonist (LABA) medicines, such as salmeterol (one of the medicines in ADVAIR HFA), have an increased risk of death from asthma problems. It is not known whether fluticasone propionate, the other medicine in ADVAIR HFA, reduces the risk of death from asthma problems seen with salmeterol. • Call your healthcare provider if breathing problems worsen over time while using ADVAIR HFA.

You may need different treatment. • Get emergency medical care if: • your breathing problems worsen quickly. • you use your rescue inhaler, but it does not relieve your breathing problems. • ADVAIR HFA should be used only if your healthcare provider decides that your asthma is not well controlled with a long-term asthma control medicine, such as an inhaled corticosteroid. • When your asthma is well controlled, your healthcare provider may tell you to stop taking ADVAIR HFA.
