An open label, randomized comparative study of levofloxacin and amoxicillin/clavulanic acid in the treatment of purulent sinusitis in adult Thai patients.

Abstract：

:The objective of the study was to compare the clinical efficacy and bacteriological response of levofloxacin and amoxicillin/clavulanic acid (co-amoxiclav) in the treatment of purulent maxillary sinusitis. Sixty patients randomly received either levofloxacin 300 mg orally once daily (LEV group) or co-amoxiclav 625 mg three times a day (COA group) for 14 days. Thirty four patients were in the LEV group and 26 patients were in the COA group. The mean total symptom score was significantly decreased after treatment and was comparable between both groups. Radiological improvement was 61.8% in the LEV group (41.2% resolution, 20.6% improvement) and 61.5% in the COA group (26.9% resolution, 34.6% improvement). Pretreatment maxillary antral aspiration cultures were positive in 28 patients (82.4%) in the LEV group and 20 patients (76.9%) in the COA group. Bacteriological eradication was 78.5% in the LEV group and 70.0% in the COA group, which was not significantly different. In the LEV group, the eradication rate for major pathogens of acute sinusitis was 100% for H. influenzae (both betalactamase +ve and -ve), 100% for S. pneumoniae and S. aureus, 100% for Neisseria species, and 66.7% for P. aeruginosa. The eradication rate in the COA group was 75% for H. influenzae (both betalactamase +ve and -ve), 100% for S. pnumoniae and S. aureus, 50% for Neisseria species, and 0% for P. aeruginosa. There were no significant changes in vital sign measurements or hemato-biochemical parameters at the end of treatment as compared to baseline values, in both groups. Adverse events were found in 8.8% of patient in the LEV group and in 7.7% of patients in the COA group. Adverse events included nausea, abdominal pain, and diarrhea. All the adverse events in both groups were mild and resolved spontaneously. This study demonstrated that levofloxacin 300 mg orally once daily was as effective and safe as amoxicillin/clavulanic acid 625 mg three times a day in the treatment of maxillary sinusitis, either acute or acute exacerbation. Both drugs showed bacteriological efficacy that was not significantly different. The once daily dosage regimen is more applicable, convenience and has better compliance.
