From the Guidelines
Community-acquired pneumonia (CAP) in geriatric patients should be treated with antibiotics for a duration of 5-7 days, with extension to 10-14 days for complicated cases or certain pathogens like Pseudomonas, and should include broader antibiotic coverage to account for the higher risk of resistant organisms and atypical pathogens.
Treatment Options
For outpatient treatment of non-severe CAP in older adults, amoxicillin-clavulanate 875/125 mg twice daily plus azithromycin 500 mg on day one followed by 250 mg daily for 4 more days is recommended 1.
- For hospitalized patients, ceftriaxone 1-2 g IV daily plus azithromycin 500 mg IV/oral daily is appropriate.
- Geriatric patients often require special considerations including lower initial dosing due to decreased renal function, careful monitoring for drug interactions with existing medications, and assessment of swallowing ability for oral medications.
Supportive Care
Supportive care with adequate hydration, oxygen therapy if needed, and early mobilization is essential.
- Pneumococcal and influenza vaccinations are crucial for prevention.
- The use of newer antibiotics such as solithromycin, nemonaxacin, delafoxacin, omadacycline, and lefamulin may be considered in certain cases, but their use should be guided by local resistance patterns and patient-specific factors 1.
Duration of Treatment
The duration of treatment should be guided by clinical stability, with a minimum of 5 days of treatment recommended 1.
- Shorter treatment durations (≤6 days) have been shown to be as effective as longer treatment durations (≥7 days) in terms of clinical cure rates, with fewer serious adverse events and potentially lower mortality 1.
- The use of biomarkers such as procalcitonin (PCT) can help guide antibiotic de-escalation and reduce the duration of treatment 1.
From the FDA Drug Label
2 Community-Acquired Pneumonia: 7 to 14 Day Treatment Regimen Levofloxacin tablets are indicated for the treatment of community-acquired pneumonia due to methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae (including multi-drug-resistant Streptococcus pneumoniae [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Chlamydophila pneumoniae, Legionella pneumophila, or Mycoplasma pneumoniae [see Dosage and Administration (2.1) and Clinical Studies (14.2)].
3 Community-Acquired Pneumonia: 5 Day Treatment Regimen Levofloxacin tablets are indicated for the treatment of community-acquired pneumonia due to Streptococcus pneumoniae (excluding multi-drug-resistant isolates [MDRSP]), Haemophilus influenzae, Haemophilus parainfluenzae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae [see Dosage and Administration (2.1) and Clinical Studies (14.3)].
Treatment options for community-acquired pneumonia (CAP) in geriatric patients include:
- Levofloxacin tablets for 7 to 14 days for CAP due to certain susceptible microorganisms, including methicillin-susceptible Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, and others 2
- Levofloxacin tablets for 5 days for CAP due to certain susceptible microorganisms, including Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae, and others 2
- Azithromycin for injection, with caution due to potential increased risk of torsades de pointes arrhythmia in elderly patients 3
From the Research
Treatment Options for Community-Acquired Pneumonia (CAP) in Geriatric Patients
The treatment of community-acquired pneumonia (CAP) in geriatric patients involves various considerations, including the severity of the disease, the presence of comorbidities, and the potential for antimicrobial resistance. The following are some treatment options for CAP in geriatric patients:
- For low-risk pneumonia, an aminopenicillin such as amoxicillin with or without a β-lactamase inhibitor is frequently recommended 4.
- Monotherapy with macrolides is also possible, although macrolide resistance is of concern 4, 5.
- For hospitalized patients with non-severe pneumonia, empirical antibacterial therapy with an aminopenicillin in combination with a β-lactamase inhibitor, or with fluoroquinolone monotherapy, is commonly recommended 4.
- In severe pneumonia, ureidopenicillins with β-lactamase inhibitors, broad-spectrum cephalosporins, macrolides, and fluoroquinolones are used 4.
- High-dose levofloxacin has been shown to be effective as single-agent therapy for treating CAP, covering atypical pathogens 6.
- The use of azithromycin, telithromycin, and fluoroquinolones in short-course regimens has been shown to be efficacious, safe, and tolerable in patients with CAP 5.
- Elderly patients with CAP, except those who are severely ill, can be treated empirically with once-daily antibiotic monotherapy in the initial phase, using a third-generation fluoroquinolone preparation or a new macrolide 7.
Considerations for Treatment
When treating CAP in geriatric patients, the following considerations should be taken into account:
- The severity of the disease, which can be assessed using validated clinical risk scores such as CURB-65 4.
- The presence of comorbidities, which can affect the response to antibiotic regimens 8.
- The potential for antimicrobial resistance, which can guide the choice of antibiotic therapy 4, 5.
- The need for timely administration of antibacterials, oxygen supply in case of hypoxaemia, and fluid management and dose adjustments according to kidney function 4.
