What medications would you prescribe for a newly diagnosed Chronic Obstructive Pulmonary Disease (COPD) patient, an older adult with a history of smoking and possible co-morbidities?

Initial Pharmacological Management for Newly Diagnosed COPD

Start with a long-acting bronchodilator as your first-line therapy—either a long-acting muscarinic antagonist (LAMA) or long-acting beta-agonist (LABA)—based on the patient's symptom burden and exacerbation history. 1

Treatment Algorithm Based on GOLD Classification

The 2017 GOLD guidelines provide a structured approach to initial therapy based on symptom severity and exacerbation risk 1:

Group A (Low Symptoms, Low Exacerbation Risk)

• Offer a bronchodilator to reduce breathlessness, either short-acting (SABA or SAMA) or long-acting (LABA or LAMA), depending on symptom frequency 1
• If symptoms are minimal or absent, no drug treatment is necessary 1
• Continue the bronchodilator only if symptomatic benefit is demonstrated 1

Group B (High Symptoms, Low Exacerbation Risk)

• Initiate a long-acting bronchodilator (LABA or LAMA) as first-line therapy 1
• Long-acting bronchodilators are superior to short-acting agents taken intermittently for symptom control 1
• For patients with persistent breathlessness on monotherapy, escalate to dual long-acting bronchodilator therapy (LABA/LAMA combination) 1
• For severe breathlessness at presentation, consider starting with two bronchodilators immediately 1

Group C (Low Symptoms, High Exacerbation Risk)

• Start with LAMA monotherapy as the preferred agent for exacerbation prevention 1
• LAMAs have greater effect on exacerbation reduction compared to LABAs and decrease hospitalizations 1

Group D (High Symptoms, High Exacerbation Risk)

• Initiate LABA/LAMA combination therapy as first-line treatment 1
• This recommendation is based on superior patient-reported outcomes, better exacerbation prevention compared to LABA/ICS, and lower pneumonia risk than ICS-containing regimens 1
• If single bronchodilator is chosen initially, prefer LAMA over LABA for exacerbation prevention 1

Critical Considerations for Inhaled Corticosteroids (ICS)

Do not use ICS monotherapy in COPD—it is not recommended 1. However, ICS combined with LABA may be appropriate in specific circumstances:

• Consider ICS/LABA combination for patients with history of exacerbations despite appropriate long-acting bronchodilator therapy 1
• ICS use increases risk of pneumonia, oral candidiasis, hoarse voice, and skin bruising 1
• Patients at higher risk for pneumonia include current smokers, age ≥55 years, prior exacerbation/pneumonia history, BMI <25 kg/m², or severe airflow limitation 1
• For Group A patients with persistent exacerbations, prefer LABA/LAMA over LABA/ICS due to pneumonia risk 1

Essential Non-Pharmacological Interventions

Smoking Cessation (Highest Priority)

Smoking cessation is the single most important intervention that influences the natural history of COPD 1:

• Implement a comprehensive five-step smoking cessation program with both pharmacotherapy and behavioral support 1
• Offer nicotine replacement therapy, which increases long-term abstinence rates 1
• Add varenicline, bupropion, or nortriptyline as part of an interventional program (not as sole therapy) 1
• The combination of pharmacotherapy and behavioral support increases cessation rates beyond either alone 1

Vaccinations

• Administer influenza vaccine annually—reduces serious illness, death, and exacerbation frequency 1
• Provide pneumococcal vaccinations (PCV13 and PPSV23) for all patients ≥65 years 1

Common Pitfalls to Avoid

• Avoid theophyllines as routine therapy—they provide only modest benefit with significant side effects and require monitoring 1
• Do not prescribe long-term oral corticosteroids—no evidence of benefit with numerous side effects 1
• Avoid beta-blocking agents (including eye drops) in COPD patients 1
• Do not use prophylactic antibiotics continuously or intermittently in stable COPD 1
• Ensure proper inhaler technique at every visit—incorrect technique is a major cause of treatment failure 1

Monitoring and Follow-Up

• Verify symptomatic improvement with prescribed bronchodilators; discontinue if ineffective 1
• Review inhaler technique at each visit to ensure proper drug delivery 1
• Assess for treatment response using objective measures (spirometry) rather than subjective improvement alone 1
• Consider a trial of oral corticosteroids (30 mg prednisolone daily for 2 weeks with spirometric assessment) in moderate to severe disease to identify the 10-20% of patients who demonstrate objective improvement 1
