Moxifloxacin vs amoxicillin/clavulanate in the treatment of acute sinusitis

Am J Otolaryngol. 2007 Mar-Apr;28(2):78-82. doi: 10.1016/j.amjoto.2006.06.016.


Purpose: The aim of this study was to compare the efficacy and safety of moxifloxacin with that of amoxicillin/clavulanate for the treatment of acute bacterial sinusitis in adults.

Materials and methods: Five hundred seventy-five patients from Latin American countries were randomized to receive oral moxifloxacin 400 mg once daily for 7 days, or oral amoxicillin/clavulanate 500/125 mg 3 times daily for 10 days, in a prospective, open study.

Results: At the test-of-cure visit (7-14 days after the end of therapy), the clinical success rate in the moxifloxacin group was 93.4% similar to that in the amoxicillin/clavulanate group (92.7%). Documented bacteriological eradication plus presumed eradication rates in the moxifloxacin (96.5%) and the amoxicillin/clavulanate (96.7%) groups were also similar. Drug-related adverse events were recorded in 32.2% of patients in the moxifloxacin group and 29.7% in the amoxicillin/clavulanate group. Patient discontinuation in the trial due to adverse events occurred for 10 patients in the moxifloxacin group and 6 in the amoxicillin/clavulanate group.

Conclusions: Overall, in terms of clinical and bacteriological response, moxifloxacin was equivalent to amoxicillin/clavulanate for the treatment of acute bacterial sinusitis in adults.
