For inpatient CAP, which intravenous therapy option is listed?

• A. Amoxicillin
• B. Doxycycline
• C. Azithromycin
• D. IV Levaquin

Answer: (D)

Inpatient CAP requires an IV antibiotic with broad coverage that includes typical pneumonia pathogens and atypical organisms, along with good lung penetration. An IV fluoroquinolone like levofloxacin fits this need because it effectively covers common bacteria such as Streptococcus pneumoniae and Haemophilus influenzae, as well as atypicals like Mycoplasma and Chlamydophila, all in a single IV agent. This makes it a convenient, reliable option for hospitalized patients who need IV therapy and may not tolerate oral meds.

Amoxicillin is typically given orally and has limited atypical coverage, so it isn’t ideal for an inpatient IV regimen. Doxycycline can be given IV but isn’t as universally reliable for inpatient CAP as a single IV agent with broad coverage. Azithromycin can be given IV, but in the hospital it’s usually used in combination with a beta-lactam rather than as the sole IV therapy, and may not provide as robust coverage in all inpatient scenarios.
