Ceftizoxime vs. cefotaxime--a comparative randomized multicenter study

One hundred and fourteen hospitalized patients with moderate or severe infections were assigned at random, in four medical centers, to receive either ceftizoxime or cefotaxime, administered intravenously in a dosage of 1 to 2 g every 8 h. Of 96 patients evaluable for efficacy, 24 (25%) had bacteremia, 46 (48%) had urinary tract infections and 9 (9%) had pneumonias. Half the patients had been treated ineffectively by other antibiotics prior to the study drug treatment. The overall clinical efficacy was 90% in both treatment groups and 83% in both groups with bacteremia. All patients with urinary tract infection were cured by both agents. Bacteriological eradication rate was 95% in both groups. Adverse reactions, though mild, were more frequent in the cefotaxime group (13.5%) than in the ceftizoxime group (6.8%); superinfection rate was higher in the ceftizoxime group. Both antibiotics were highly and equally efficacious in the therapy of severe infections in hospitalized patients.
