What are the treatment options for Chronic Obstructive Pulmonary Disease (COPD)?

Treatment Options for COPD

The American Thoracic Society recommends LAMA/LABA combination therapy, such as tiotropium/olodaterol, as first-line treatment for COPD, providing superior bronchodilation, improving lung function, reducing symptoms, and decreasing exacerbation risk. 1

Diagnosis and Assessment

• COPD diagnosis requires objective measurement via spirometry
• Post-bronchodilator FEV1/FVC <0.70 confirms persistent airflow limitation
• Severity classification based on FEV1:
  • Mild: >80% predicted
  • Moderate: 50-80% predicted
  • Severe: 30-50% predicted
  • Very severe: <30% predicted 1

Pharmacological Treatment Algorithm

First-Line Therapy

• LAMA/LABA combination therapy (e.g., tiotropium/olodaterol)
  • Superior bronchodilation compared to monotherapy
  • Improves lung function and reduces symptoms
  • Decreases exacerbation risk 1
  • Tiotropium has been shown to be more effective than salmeterol in preventing exacerbations 2

Monotherapy Options (if combination therapy not tolerated)

• LAMA preferred over LABA for patients with frequent exacerbations
• Short-acting bronchodilators (SABA or SAMA) for intermittent symptoms or rescue therapy 1
• Tiotropium (LAMA) administered as 18 μg once daily via inhaler 3
• Salmeterol (LABA) administered as 50 μg twice daily via inhaler 4

Add-on Therapies for Persistent Symptoms/Exacerbations

1. For patients with FEV1 < 50% predicted and chronic bronchitis: Consider roflumilast 1
2. For patients with blood eosinophil count ≥300 cells/μL or history of asthma: Consider LABA/LAMA/ICS triple therapy 1
3. For former smokers with persistent exacerbations: Consider macrolide therapy (e.g., azithromycin) 1

Non-Pharmacological Interventions

Lifestyle Modifications

• Smoking cessation - crucial at all disease stages
  • Active cessation programs with nicotine replacement therapy lead to higher sustained quit rates 1
• Exercise and pulmonary rehabilitation
  • Cornerstone of management for all symptomatic patients
  • Improves exercise performance and reduces breathlessness 1
• Nutrition and weight management
  • Essential for patients with COPD 1

Oxygen Therapy

• Long-term oxygen therapy (LTOT)
  • Prolongs life in hypoxemic patients with COPD
  • Indicated for patients with PaO2 <7.3 kPa or high cylinder use 1
• Short-burst oxygen for breathlessness lacks evidence 1

Surgical Options

• For selected patients:
  • Lung volume reduction surgery for upper-lobe predominant emphysema
  • Bullectomy for isolated bullous disease
  • Lung transplantation for end-stage disease (patients <65 years with FEV1 <25% predicted) 1
• Bronchoscopic lung volume reduction (BLVR) for select patients with severe COPD and upper-lobe predominant emphysema 1

Prevention and Vaccinations

• Annual influenza vaccination recommended for all COPD patients
• Pneumococcal vaccination recommended 1

Acute Exacerbations Management

• Systemic corticosteroids for acute exacerbations
• Antibiotics for exacerbations with increased sputum purulence or requiring mechanical ventilation 1

Important Cautions and Monitoring

• Inhaled corticosteroids (ICS) increase the risk of pneumonia in COPD patients 1
• Opioids at low doses may be considered for refractory dyspnea in severe disease 1
• LAMA (tiotropium) may cause dry mouth as a side effect 3
• LABA (salmeterol) is NOT indicated for the relief of acute bronchospasm 4

Palliative Care Considerations

• Assessment and treatment of depression is essential
• Focus on relief of dyspnea, pain, anxiety, depression, fatigue, and poor nutrition
• Advance care planning should include discussions with patients and families 1

When to Refer to Specialist Care

Consider referral in cases of:

• Diagnostic uncertainty
• Rapid disease progression
• Severe symptoms despite optimal therapy
• Consideration for advanced therapies 1
