Treatment of Reactive Airway Disease
The recommended treatment for reactive airway disease follows a stepwise approach, starting with inhaled short-acting beta agonists as needed for all patients, progressing to low-dose inhaled corticosteroids as preferred controller therapy for persistent symptoms, and adding long-acting beta agonists or other agents for more severe cases. 1
Initial Assessment and Treatment
- Begin with a short-acting beta agonist (SABA) as needed for quick symptom relief in all patients with reactive airway disease 1
- Patient education, environmental control measures, and management of comorbidities should be addressed at every step of treatment 1
- Assess symptom frequency and severity to determine appropriate step of therapy 1
Stepwise Treatment Approach
Step 1: Intermittent Symptoms
- Preferred treatment: Inhaled short-acting beta agonist as needed 1
- Use of SABA more than twice weekly indicates inadequate control and need to step up therapy 1
Step 2: Mild Persistent Symptoms
- Preferred treatment: Low-dose inhaled corticosteroid (ICS) 1
- Alternative treatments: Leukotriene receptor antagonist (e.g., montelukast), cromolyn, nedocromil, or theophylline 1
- Note that low-dose ICS achieves 80-90% of maximum therapeutic benefit in adult asthma 2
Step 3: Moderate Persistent Symptoms
- Preferred treatment: Low-dose ICS plus long-acting beta agonist (LABA) OR medium-dose ICS 1
- Alternative treatment: Low-dose ICS plus leukotriene receptor antagonist, theophylline, or zileuton 1
- Combination therapy with ICS and LABA (e.g., fluticasone/salmeterol) provides greater asthma control than increasing ICS dose alone 3
Step 4: Moderate-to-Severe Persistent Symptoms
- Preferred treatment: Medium-dose ICS plus LABA 1
- Alternative treatment: Medium-dose ICS plus leukotriene receptor antagonist, theophylline, or zileuton 1
Step 5: Severe Persistent Symptoms
- Preferred treatment: High-dose ICS plus LABA 1
- Consider omalizumab for patients with allergic components 1
Step 6: Very Severe Persistent Symptoms
- Preferred treatment: High-dose ICS plus LABA plus oral corticosteroid 1
- Consider omalizumab for patients with allergies 1
Special Considerations
Children
- Treatment approach is similar but with adjusted dosing 1
- For mild persistent asthma in children, low-dose ICS is preferred 1
- Leukotriene receptor antagonists may be particularly beneficial in children with RSV-induced reactive airway disease 4
Beta-Blockers in Patients with Reactive Airways
- Cardioselective beta-blockers can be used cautiously in patients with mild to moderate reactive airway disease when clinically indicated 5
- Start with low doses of cardioselective agents (e.g., metoprolol) and monitor closely 5
Treatment Adjustments
- Step up treatment if control is inadequate (check adherence, environmental control, and comorbid conditions first) 1
- Step down treatment if asthma is well-controlled for at least three months 1
- Use of SABA more than two days per week for symptom relief generally indicates inadequate control 1
Common Pitfalls to Avoid
- Failing to recognize persistent symptoms that require controller medications 1
- Overreliance on short-acting beta agonists without addressing underlying inflammation 1
- Not stepping up therapy when symptoms are inadequately controlled 1
- Prescribing excessive doses of ICS when standard doses (200-250 μg fluticasone or equivalent) achieve 80-90% of maximum benefit 2
- Failing to consider allergic components that may benefit from specific therapies 1
