Comparison of roxithromycin with co-amoxiclav in patients with sinusitis

Abstract

In an open, randomized study of 60 patients with acute or recurrent sinusitis, the bacteriological and clinical efficacy of roxithromycin 150 mg bd were compared with those of po co-amoxiclav (625 mg) tds. Of 52 patients who underwent sinus puncture for isolation of causative organisms, 48 had pathogens sensitive to both antibiotics. Satisfactory clinical response was obtained in 93.1% (27/29) evaluable patients receiving roxithromycin and 88.8% (24/27) receiving co-amoxiclav. Tolerability was significantly better in the roxithromycin group, with 1/29 (3.4%) patients in this group experiencing gastrointestinal side-effects, compared with 7/27 (25.9%) patients in the co-amoxiclav group (P < 0.05). Although the study had limited power to detect differences, roxithromycin demonstrated clinical, bacteriological and overall efficacy similar to that of co-amoxiclav, but with better tolerability. Roxithromycin thus appears to be an effective and well-tolerated drug for the treatment of acute and recurrent sinusitis.
