Clinical Efficacy and Safety of a Short Regimen of Azithromycin Sequential Therapy vs Standard Cefuroxime Sequential Therapy in the Treatment of Community-Acquired Pneumonia: An International, Randomized, Open-Label Study

Abstract

An international, randomized, open-label, comparative study was undertaken in order to assess the efficacy and safety of azithromycin and cefuroxime, short sequential vs standard sequential therapy, respectively, in the treatment of patients with community-acquired pneumonia (CAP). 180 adult patients were included in the study. 89 patients received azithromycin 500 mg intravenously (i.v.) once daily for 1-4 days followed by azithromycin 500 mg orally once daily for 3 days. 91 patients received cefuroxime 1.5 g i.v. three times daily for 1-4 days followed by cefuroxime axetil 500 mg orally twice daily for 7 days. Clinical efficacy was achieved in 67/82 (81.7%) patients treated with azithromycin, and in 73/89 (82.0%) patients treated with cefuroxime. The mean duration of total (i.v. and oral) therapy was significantly shorter for the azithromycin group than for the cefuroxime group (6.2 days vs 10.1 days). Adverse events were recorded in 38.2% of patients treated with azithromycin, and in 29.7% of patients treated with cefuroxime (p = 0.20). Shorter sequential i.v.-to-oral azithromycin therapy of patients with CAP was as effective as standard sequential i.v.-to-oral cefuroxime therapy.
