What is Advair?
Advair is a fixed-dose combination inhaler containing fluticasone propionate (an inhaled corticosteroid) and salmeterol (a long-acting beta2-agonist) used for long-term maintenance treatment of asthma and chronic obstructive pulmonary disease (COPD). 1, 2
Primary Indications
Asthma Management
- Advair is indicated for maintenance treatment of asthma in adults and children aged 4 years and older who require both an inhaled corticosteroid and long-acting beta2-agonist for disease control 1
- The combination provides superior symptom control, improved lung function, and reduced exacerbation rates compared to inhaled corticosteroid monotherapy 1
- This medication should never be used for acute bronchospasm or as rescue therapy—it is strictly a maintenance controller medication 3
COPD Management
- In the United States, Advair 50/250 mcg twice daily is approved for COPD associated with chronic bronchitis 2
- In the European Union, the 50/500 mcg dosage is approved for severe COPD with repeat exacerbations and significant symptoms despite bronchodilator therapy 2
- The combination significantly reduces annual COPD exacerbations, particularly in severe disease, and improves health-related quality of life more than monotherapy 2, 4
How It Works
Dual Mechanism of Action
- Fluticasone propionate (the corticosteroid component) reduces airway inflammation, which is the underlying pathophysiology in both asthma and COPD 1
- Salmeterol (the long-acting beta2-agonist) provides sustained bronchodilation for up to 12 hours, improving airflow and reducing symptoms 1, 2
- The combination produces additive effects that are superior to either component alone 5
Dosing and Administration
Available Formulations
- Advair is available as a dry powder inhaler (Diskus) or metered-dose inhaler (MDI) with various strength combinations 1, 2
- Common strengths include 100/50,250/50, and 500/50 mcg (fluticasone/salmeterol) 3
- Standard dosing is one inhalation twice daily, approximately 12 hours apart 1, 2
Proper Administration Technique
- For MDI formulations, always use a spacer or valved holding chamber to enhance lung deposition and reduce local side effects 3
- Rinse mouth thoroughly with water and spit after each use to prevent oral thrush (candidiasis) 3
- For young children, a face mask that fits snugly over the nose and mouth should be used with the spacer 3
Clinical Evidence and Efficacy
Superiority Over Alternatives
- Advair improves lung function and asthma symptoms more effectively than fluticasone propionate alone, montelukast (with or without fluticasone), or theophylline plus fluticasone 1
- The combination is more effective than doubling the dose of inhaled corticosteroids alone for achieving asthma control 3, 6
- In COPD, Advair 50/500 mcg significantly reduced the rate of decline in lung function over 3 years and was associated with lower exacerbation rates than component monotherapies 4
Stepwise Treatment Positioning
- Advair is appropriate for Step 3-4 care in the stepwise asthma management approach 3, 6
- Step 3 includes low-dose ICS plus LABA (like Advair 100/50) or medium-dose ICS alone 3
- Step 4 includes medium-dose ICS plus LABA (like Advair 250/50) 3
Critical Safety Considerations
Black Box Warning
- Long-acting beta2-agonists like salmeterol increase the risk of asthma-related deaths when used as monotherapy 3, 6
- LABAs must ALWAYS be combined with an inhaled corticosteroid—the fixed-combination inhaler ensures appropriate use 1, 6
- Never discontinue the corticosteroid component when a patient is on combination therapy 7
Common Adverse Effects
- Local effects include cough, dysphonia (hoarseness), and oral thrush, which can be minimized with proper mouth rinsing 3
- Systemic effects are rare at low-to-medium doses but may include adrenal suppression, growth velocity reduction in children, and bone mineral density effects at higher doses 3
- Some corticosteroid-related adverse events are increased with fluticasone-containing products versus salmeterol monotherapy 2
Important Precautions
- Withdrawal from fluticasone propionate, including combination therapy, needs careful management to minimize COPD exacerbations 2
- Monitor growth velocity in children receiving medium-to-high doses, as transient growth suppression may occur (approximately 1 cm) but is generally non-progressive 3
- Reassess asthma control every 2-6 weeks initially after starting therapy 3, 7
When to Use Advair
Appropriate Clinical Scenarios
- Patients with moderate-to-severe persistent asthma inadequately controlled on low-dose inhaled corticosteroids alone 3, 6
- Adults and children ≥5 years with moderate persistent asthma requiring Step 3 care 6
- Patients with COPD who have repeat exacerbations despite bronchodilator therapy 2
- For children younger than 5 years, medium-dose ICS monotherapy is preferred over combination therapy due to lack of safety data for LABAs in this age group 3, 6
When NOT to Use Advair
- Never use for acute symptom relief or rescue therapy 3
- Not appropriate as initial therapy for mild persistent asthma—low-dose ICS monotherapy is preferred first-line 8
- Avoid in patients who can achieve adequate control with low-dose ICS alone 3
Cost-Effectiveness
- In cost-utility analyses, Advair compares favorably with fluticasone propionate alone or oral montelukast in patients with uncontrolled asthma 1
- The fixed-combination inhaler may encourage patient compliance compared to using separate inhalers 2
Special Considerations for COPD
- Advair 50/500 mcg was associated with a trend toward reduced mortality versus placebo in the TORCH study (p=0.052), though this did not reach statistical significance 4
- The INSPIRE trial suggested significantly lower mortality rates with Advair compared to tiotropium monotherapy in COPD patients 4
- Patients must be treated for at least 3 months before real improvement in lung function is achieved in COPD 5
