Ceftriaxone combination therapy versus respiratory fluoroquinolone monotherapy for community-acquired pneumonia: A meta-analysis

Published:February 02, 2018DOI:



      The goal of this study was to investigate whether ceftriaxone combination therapy is associated with better clinical outcomes than respiratory fluoroquinolone monotherapy for adults with community-acquired pneumonia (CAP). We conducted a meta-analysis of published studies.


      Using the PubMed, EMBASE, and Cochrane Library databases, we performed a literature search of available randomized controlled trials (RCTs) published as original articles before September 2017.


      Nine RCTs, involving 1520 patients, were included in the meta-analysis. The pooled relative risks (RRs) for the efficacy of ceftriaxone combination therapy versus respiratory fluoroquinolones monotherapy were 0.96 (95% CI: 0.92–1.01), based on clinically evaluable populations, and 0.93 (95% CI: 0.88–0.99) based on intention-to-treat (ITT) populations. No statistically significant differences were observed in microbiological treatment success (pooled RR = 0.99, 95% CI: 0.90–1.09), although drug-related adverse events were significantly lower with ceftriaxone combination therapy than with respiratory fluoroquinolones monotherapy (pooled RR = 1.27, 95% CI: 1.04–1.55).


      Current evidence showed that the efficacy of ceftriaxone combination therapy was similar to respiratory fluoroquinolone monotherapy for hospitalized CAP patients, and was associated with lower drug-related adverse events.
