For inpatient treatment of community-acquired pneumonia, which antibiotic is preferred?

In the treatment of community-acquired pneumonia (CAP) in an inpatient setting, the choice of antibiotic often depends on various factors, such as the severity of pneumonia, local resistance patterns, and the patient's individual clinical circumstances. Levofloxacin, a fluoroquinolone, is frequently recommended for hospitalized patients, particularly those who require intravenous therapy or those with more severe cases.

Levofloxacin is a broad-spectrum antibiotic that effectively targets common pathogens associated with CAP, including Streptococcus pneumoniae, Haemophilus influenzae, and atypical organisms like Mycoplasma pneumoniae and Chlamydophila pneumoniae. Its broad coverage makes it suitable for patients who may have more complex presentations or those at risk for drug-resistant organisms.

Other antibiotics, such as azithromycin and doxycycline, are typically more effective for outpatient management or in milder cases of CAP. They provide good coverage for atypical pathogens but may lack the broad-spectrum activity required in hospitalized patients. Vancomycin, while effective for resistant Gram-positive infections, is not routine for CAP unless there is a concern for methicillin-resistant Staphylococcus aureus (MRSA), which would typically be indicated by specific clinical findings or risk factors.
