Antibiotic Regimens for Pneumonia and COPD Exacerbations

COPD Exacerbation Antibiotic Therapy

The European Respiratory Society recommends antibiotic selection based on disease severity, risk factors for specific pathogens, and local resistance patterns, with amoxicillin or tetracycline recommended for mild cases and co-amoxiclav for moderate-severe cases without Pseudomonas risk factors 1, 2
Antibiotics should be prescribed when patients exhibit all three cardinal symptoms (Anthonisen Type I): increased dyspnea, increased sputum volume, AND increased sputum purulence, as recommended by the European Respiratory Society 2
Patients with severe exacerbations requiring invasive or noninvasive mechanical ventilation should receive antibiotics, according to the European Respiratory Society 2, 4

For mild COPD exacerbation, the European Respiratory Society recommends first-line treatment with amoxicillin (500-1000 mg three times daily) or doxycycline (100 mg twice daily) 1, 3
For moderate-severe COPD exacerbation without P. aeruginosa risk factors, the European Respiratory Society recommends first-line treatment with co-amoxiclav (oral) 1, 5

The European Respiratory Society recommends a standard duration of 7-10 days for COPD exacerbations 1, 6
Shorter courses (5 days) with levofloxacin or moxifloxacin have shown similar efficacy to 10-day courses with β-lactams, according to the European Respiratory Society 1, 6

The European Respiratory Society recommends performing careful microbiological reassessment and considering broader antibiotic coverage against P. aeruginosa, resistant S. pneumoniae, and non-fermenters for non-responders 7, 5

The European Respiratory Society recommends sputum cultures or endotracheal aspirates for severe exacerbations (Group C patients), patients with risk factors for P. aeruginosa, and prior antibiotic or oral steroid treatment 2
