What is the recommended treatment for Chronic Obstructive Pulmonary Disease (COPD)?

COPD Treatment Recommendations

For stable COPD management, initiate treatment with long-acting bronchodilators as the cornerstone of therapy, with LABA/LAMA combination therapy preferred for patients with severe disease and high exacerbation risk, while reserving inhaled corticosteroids primarily for patients with persistent exacerbations despite optimal bronchodilator therapy. 1, 2

Smoking Cessation - The Critical First Step

• Smoking cessation is the single most important intervention that modifies disease progression and must be addressed at every clinical encounter regardless of disease severity. 2, 3
• Nicotine replacement therapy (gum or transdermal patches) combined with behavioral interventions significantly increases quit rates and should be actively offered. 2

Pharmacological Management by Disease Severity

Mild COPD (Low Symptoms, Low Exacerbation Risk)

• Patients with no symptoms require no drug treatment. 2, 3
• For symptomatic patients, initiate short-acting bronchodilators (β2-agonist or anticholinergic) as needed via appropriate inhaler device. 2, 3

Moderate COPD (Moderate Symptoms, Low Exacerbation Risk - Group B)

• Initiate long-acting bronchodilator monotherapy as first-line treatment. 1, 2
• Long-acting muscarinic antagonists (LAMAs) are preferred over LABAs for exacerbation prevention when choosing monotherapy. 1, 2
• There is no evidence to recommend one class of long-acting bronchodilators over another for symptom relief alone; the choice depends on individual patient response. 1
• For patients with persistent breathlessness on monotherapy, escalate to dual bronchodilator therapy (LABA/LAMA). 1, 2
• For patients with severe breathlessness at presentation, consider initiating dual bronchodilator therapy immediately. 1

Severe COPD (High Symptoms, High Exacerbation Risk - Group D)

• Initiate LABA/LAMA combination therapy as first-line treatment. 1, 2
• This recommendation is based on three key factors: LABA/LAMA combinations show superior patient-reported outcomes compared to single bronchodilators, superior exacerbation prevention compared to LABA/ICS combinations, and lower pneumonia risk compared to ICS-containing regimens. 1

Role of Inhaled Corticosteroids (ICS)

• ICS should NOT be first-line therapy for most COPD patients due to increased pneumonia risk. 1
• Add ICS to LABA/LAMA therapy only for patients with:
  • FEV1 <50% predicted AND ≥2 exacerbations in the previous year, OR 2
  • Blood eosinophil counts ≥150-200 cells/µL, OR 2
  • Features suggestive of asthma-COPD overlap. 1, 2
• LABA/ICS may be considered as initial therapy specifically for patients with high blood eosinophil counts or asthma-COPD overlap features. 1

Escalation Strategy for Persistent Exacerbations

For patients on LABA/LAMA who continue to exacerbate, follow this algorithm: 1

1. First escalation: Add ICS to create LABA/LAMA/ICS triple therapy. 1
2. Alternative pathway: Switch to LABA/ICS, then add LAMA if inadequate response. 1
3. If still exacerbating on triple therapy, consider:
   • Adding roflumilast for patients with FEV1 <50% predicted, chronic bronchitis, and particularly if hospitalized for exacerbation in the previous year. 1
   • Adding a macrolide in former smokers (weigh risk of developing resistant organisms). 1
   • Stopping ICS if no benefit observed, given elevated pneumonia risk. 1

Critical Inhaler Technique Considerations

• Inhaler technique must be demonstrated before prescribing and regularly checked at follow-up visits. 2, 3
• 76% of COPD patients make important errors with metered-dose inhalers, while 10-40% make errors with dry powder inhalers. 2
• Select an appropriate inhaler device to ensure efficient delivery based on patient ability and preference. 2, 3
• Patients should rinse mouth with water without swallowing after ICS-containing inhalers to reduce oropharyngeal candidiasis risk. 4

Non-Pharmacological Interventions

Pulmonary Rehabilitation

• Comprehensive pulmonary rehabilitation programs should be offered to all patients with high symptom burden (Groups B, C, and D). 1, 2
• Programs must include physiotherapy, muscle training, nutritional support, and education. 2
• Rehabilitation increases exercise tolerance and improves quality of life. 2
• Combination of constant load or interval training with strength training provides better outcomes than either method alone. 1

Vaccinations

• Annual influenza vaccination is recommended for all COPD patients. 2, 3
• Pneumococcal vaccination should be considered, with revaccination every 5-10 years. 2

Long-Term Oxygen Therapy (LTOT)

• Prescribe LTOT for patients with PaO2 ≤55 mmHg (7.3 kPa) on arterial blood gas. 2, 3
• The goal is maintaining SpO2 ≥90% during rest, sleep, and exertion. 2
• LTOT improves survival in hypoxemic patients and should only be prescribed with objectively demonstrated hypoxemia. 2, 3
• Oxygen concentrators are the easiest mode for home use. 2

Management of Acute Exacerbations

Bronchodilator Therapy

• Short-acting inhaled β2-agonists, with or without short-acting anticholinergics, are the initial bronchodilators for acute exacerbations. 1
• Consider nebulizers if inhaler technique is inadequate during exacerbation. 2
• Initiate or continue maintenance long-acting bronchodilators as soon as possible before hospital discharge. 1

Systemic Corticosteroids

• Systemic corticosteroids (30-40 mg prednisone daily for 5-7 days) improve lung function, oxygenation, and shorten recovery time. 1, 2
• Exacerbations with increased sputum or blood eosinophils may be more responsive to systemic steroids. 1

Antibiotics

• Antibiotics are indicated when ≥2 of the following are present: increased breathlessness, increased sputum volume, purulent sputum. 2
• When indicated, antibiotics shorten recovery time and reduce risk of early relapse, treatment failure, and hospitalization duration. 1
• Typical course is 7-14 days. 2

Ventilatory Support

• Non-invasive ventilation (NIV) should be the first mode of ventilation for acute respiratory failure. 1

Critical Pitfalls to Avoid

• Beta-blocking agents (including eyedrop formulations) must be avoided in COPD patients. 2, 3
• Methylxanthines (theophyllines) are not recommended due to side effects and limited value. 1, 3
• There is no evidence supporting prophylactic antibiotics given continuously or intermittently. 2, 3
• Do not use more than 1 inhalation twice daily of prescribed LABA-containing medications, as higher doses increase adverse effects. 4
• Patients using LABA/LAMA or LABA/ICS combinations should not use additional LABA for any reason. 4
• Antitussives cannot be recommended for COPD. 1
• Drugs approved for primary pulmonary hypertension are not recommended for pulmonary hypertension secondary to COPD. 1

Advanced Disease Considerations

• For selected patients with very severe COPD, consider lung volume reduction surgery (endoscopic bronchial one-way valves or lung coils). 1
• Lung transplantation may be considered for patients with BODE index >7, FEV1 <15-20% predicted, ≥3 severe exacerbations in the previous year, or one severe exacerbation with acute hypercapnic respiratory failure. 1

Monitoring and Follow-Up

• Routine follow-up is essential to monitor symptoms, exacerbations, and objective measures of airflow limitation. 1
• Each visit should include discussion of current therapeutic regimen and adjustment as disease progresses. 1
• Assess for development of comorbidities at each encounter. 1
