Current First-Line Treatment Recommendations for Asthma According to New Guidelines

Inhaled corticosteroids (ICSs) are the most effective first-line controller medication for persistent asthma across all age groups. 1

Stepwise Approach to Asthma Management

The current guidelines use a 6-step approach to asthma management, with treatment recommendations based on both asthma severity and level of control:

Initial Assessment and Classification

• Asthma severity should be classified as intermittent or persistent (mild, moderate, or severe) based on symptoms, nighttime awakenings, rescue medication use, activity limitation, and lung function 1
• Treatment decisions should consider both current impairment (day-to-day symptoms) and future risk (exacerbations) 1

First-Line Treatment Recommendations by Severity

1. Intermittent Asthma

   • Short-acting beta-agonists (SABAs) as needed for symptom relief 1

2. Persistent Asthma (Step 2)

   • Low-dose ICS is the preferred controller medication 1, 2
   • Alternative options include leukotriene receptor antagonists (LTRAs), though these are less effective than ICSs 1

3. Moderate Persistent Asthma (Step 3)

   • Preferred: Low-dose ICS plus long-acting beta-agonist (LABA) 1
   • Alternative: Medium-dose ICS alone or low-dose ICS plus LTRA 1

4. Moderate-to-Severe Persistent Asthma (Step 4)

   • Preferred: Medium-dose ICS plus LABA 1
   • Alternative: Medium-dose ICS plus LTRA, theophylline, or zileuton 1

5. Severe Persistent Asthma (Step 5)

   • Preferred: High-dose ICS plus LABA 1
   • Consider adding omalizumab for patients with allergies 1

6. Very Severe Persistent Asthma (Step 6)

   • Preferred: High-dose ICS plus LABA plus oral corticosteroid 1
   • Consider omalizumab for patients with allergies 1

Important Considerations for Treatment

Age-Specific Recommendations

• Treatment recommendations are now divided into three age groups: children under 5 years, children 5-11 years, and patients 12 years and older 1
• This division reflects differences in response to medications and available evidence 1

Safety Considerations

• LABAs should never be used as monotherapy due to increased risk of severe exacerbations and death 1, 3
• LABAs should always be prescribed with ICSs, preferably as a combination product to ensure adherence 3, 4
• The dose-response curve for ICSs is relatively flat; adding another medication class is often preferable to increasing ICS dose in moderate-to-severe asthma 5
• High starting doses of ICSs provide no additional clinical benefit in most efficacy parameters compared to low or moderate doses 2

Monitoring and Adjusting Therapy

• Assess asthma control at regular intervals using validated tools like the Asthma Control Test 1
• Step up therapy if needed (after checking adherence, inhaler technique, and environmental triggers) 1
• Step down if asthma is well-controlled for at least three months 1
• Consider referral to an asthma specialist for patients requiring Step 4 care or higher 1

Combination Therapy Benefits

• Adding a LABA to ICS therapy provides greater improvements in lung function and overall asthma control compared to increasing ICS dose or adding an LTRA 6
• Combination ICS/LABA inhalers improve compliance with guidelines and ensure patients receive both medications 4
• For patients with moderate-to-severe persistent asthma, combination therapy with ICS/LABA remains recommended despite the black box warning about LABA risks 1

By following these evidence-based recommendations and regularly assessing asthma control, clinicians can help patients achieve better outcomes with reduced symptoms, improved lung function, and fewer exacerbations.
