Comparison of cefotaxime with ceftriaxone given intramuscularly 12-hourly for community-acquired pneumonia

Cefotaxime 1 g intramuscularly (i.m.) 12-hourly was compared with ceftriaxone 1 g i.m. 12-hourly in adult patients requiring hospitalization with uncomplicated community-acquired pneumonia. Fifty-two patients were enrolled and two were subsequently withdrawn, leaving 50 patients who completed the study; 23 received cefotaxime and 27 received ceftriaxone. Clinical cure was achieved in 49 of the 50 patients (98%). One treatment failure occurred in a patient who received ceftriaxone. The only significant pathogen isolated from the pretreatment sputum cultures was Streptococcus pneumoniae (50%). All isolates were sensitive to both drugs. Cefotaxime 1 g i.m. 12-hourly was as effective as ceftriaxone in the treatment of patients with uncomplicated community-acquired pneumonia requiring hospital admission.
