ABSTRACT
Background: Fixed dose combination of cefpodoximeclavulanic acid and cefpodoxime both are commonly used in the treatment acute bacterial sinusitis. However, comparative clinical studies between the fixed dose combination of cefpodoxime-clavulanic acid versus cefpodoxime alone are not available. Objective: A postmarketing study was conducted to evaluate the efficacy and safety of fixed dose combination of cefpodoxime proxetil plus potassium clavulonate versus cefpodoxime proxetil in treatment of acute bacterial sinusitis. Material and methods: A total of 202 patients were enrolled in an open label, randomized, parallel group, two arms multicentric study. Patients were treated either with fixed dose combination of cefpodoxime 200 mg plus clavulanic acid 125 mg or cefpodoxime 200 mg; both given as one tablet twice daily for ten days. The efficacy was evaluated at baseline, day three, day five and day ten while the safety was assessed at screening and day 10. Statistical analysis: Intention to treat population was used to analyse the safety results while efficacy was evaluated in per protocol population. Chi square test was used to evaluate the efficacy parameters on six point Likert scale, global evaluation of efficacy and safety by investigators and patients. Results: Cure rate was higher in study group (58.43%) compared to control group (46.81%), however, the difference was not significant. No significant difference was seen in
