What are the two most appropriate antibiotics to treat community-acquired pneumonia (CAP)?

The two most appropriate antibiotics to treat community-acquired pneumonia (CAP) are a macrolide and doxycycline. Macrolides, such as azithromycin or clarithromycin, are effective against the most common pathogens associated with CAP, including Streptococcus pneumoniae and atypical bacteria like Mycoplasma pneumoniae and Chlamydophila pneumoniae.

Doxycycline, a tetracycline antibiotic, also provides coverage for these organisms and offers an alternative for patients who may have allergies to macrolides or are unable to tolerate them. The combination of a macrolide and doxycycline helps to ensure a broad spectrum of activity against both typical and atypical pathogens commonly found in CAP cases.

Other options presented include antibiotics that do not align as closely with the first-line treatment protocols established for CAP, which favor the use of macrolides in conjunction with doxycycline. Therefore, the combination of a macrolide and doxycycline is recognized as an effective and standard approach for treating community-acquired pneumonia.
