"The US Food and Drug Administration has approved AstraZeneca's Symbicort inhalation aerosol (80/4.5 mcg) for children aged 6 to 12 years with asthma that is not well controlled with an inhaled corticosteroid, the company has announced.
LABA, such as salmeterol, one of the active ingredients in ADVAIR HFA, increase the risk of asthma-related death. Data from a large placebo-controlled US trial that compared the safety of salmeterol or placebo added to usual asthma therapy showed an increase in asthma-related deaths in subjects receiving salmeterol [see WARNINGS AND PRECAUTIONS]. Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA. Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients [see WARNINGS AND PRECAUTIONS].
Systemic and local corticosteroid use may result in the following:
- Candida albicans infection [see WARNINGS AND PRECAUTIONS]
- Pneumonia in patients with COPD [see WARNINGS AND PRECAUTIONS]
- Immunosuppression [see WARNINGS AND PRECAUTIONS]
- Hypercorticism and adrenal suppression [see WARNINGS AND PRECAUTIONS]
- Reduction in bone mineral density [see WARNINGS AND PRECAUTIONS]
- Growth effects [see WARNINGS AND PRECAUTIONS]
- Glaucoma and cataracts [see WARNINGS AND PRECAUTIONS]
Clinical 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, US clinical trials (Trials 1 and 3) and 1 active-controlled 12-week US 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 inhaled corticosteroids were treated twice daily with 2 inhalations of ADVAIR HFA 45/21 or ADVAIR HFA 115/21, 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.

The incidence of common adverse reactions reported in Trial 4, a 12-week non-US clinical trial in 509 subjects previously treated with inhaled corticosteroids who were treated twice daily with 2 inhalations of ADVAIR HFA 230/21, fluticasone propionate CFC inhalation aerosol 220 mcg, or 1 inhalation of ADVAIR DISKUS 500/50 was similar to the incidences reported in Table 2.
Additional Adverse Reactions
Other adverse reactions not previously listed, whether considered drug-related or not by the investigators, that occurred in the groups receiving ADVAIR HFA with an incidence of 1% to 3% and that occurred at a greater incidence than with placebo include the following: tachycardia, arrhythmias, myocardial infarction, postoperative complications, wounds and lacerations, soft tissue injuries, ear signs and symptoms, rhinorrhea/postnasal drip, epistaxis, nasal congestion/blockage, laryngitis, unspecified oropharyngeal plaques, dryness of nose, weight gain, allergic eye disorders, eye edema and swelling, gastrointestinal discomfort and pain, dental discomfort and pain, candidiasis mouth/throat, hyposalivation, gastrointestinal infections, disorders of hard tissue of teeth, abdominal discomfort and pain, oral abnormalities, arthralgia and articular rheumatism, muscle cramps and spasms, musculoskeletal inflammation, bone and skeletal pain, muscle injuries, sleep disorders, migraines, allergies and allergic reactions, viral infections, bacterial infections, candidiasis unspecified site, congestion, inflammation, bacterial reproductive infections, lower respiratory signs and symptoms, lower respiratory infections, lower respiratory hemorrhage, eczema, dermatitis and dermatosis, urinary infections.
Laboratory Test Abnormalities
In Trial 3, there were more reports of hyperglycemia among adults and adolescents receiving ADVAIR HFA, but this was not seen in Trials 1 and 2.
In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postapproval use of any formulation of ADVAIR, fluticasone propionate, and/or salmeterol regardless of indication. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to ADVAIR, fluticasone propionate, and/or salmeterol or a combination of these factors.
Eye: Cataracts, glaucoma.
Hepatobiliary Tract and Pancreas: Abnormal liver function tests.
Infections and Infestations: Esophageal candidiasis.
Musculoskeletal: Back pain, myositis.
Neurology: Paresthesia, restlessness.
Non-Site Specific: Fever, pallor.
Psychiatry: Agitation, aggression, anxiety, depression. Behavioral changes, including hyperactivity and irritability, have been reported very rarely and primarily in children.
Respiratory: Asthma; asthma exacerbation; chest congestion; chest tightness; cough; dyspnea; immediate bronchospasm; influenza; paradoxical bronchospasm; tracheitis; wheezing; pneumonia; reports of upper respiratory symptoms of laryngeal spasm, irritation, or swelling such as stridor or choking.

ADVAIR HFA has been used concomitantly with other drugs, including short-acting beta2-agonists, methylxanthines, and intranasal corticosteroids, commonly used in patients with asthma, without adverse drug reactions [see CLINICAL PHARMACOLOGY]. No formal drug interaction trials have been performed with ADVAIR HFA.
Inhibitors 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.
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]. 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.
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 Cmax increased 1.4-fold). Three (3) subjects were withdrawn due to beta2-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.
Monoamine 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.
Beta-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 betaadrenergic blocking agents for these patients; cardioselective beta-blockers could be considered, although they should be administered with caution.
The ECG changes and/or hypokalemia that may result from the administration of non– potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by betaagonists, such as salmeterol, a component of ADVAIR HFA, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of ADVAIR HFA with non–potassium-sparing diuretics.
