Background:
Acute sinusitis constitutes a significant portion of health service utilization globally both in- and outpatient as well as emergency department visits, with 83% resulting in a prescription for an antibiotic. This study compared the efficacy of a 5-day regimen of azithromycin (a macrolid antibiotic) with a 10-day regimen of coamoxiclav (combination of an aminopenicillin with a betalactamase inhibitor) for the treatment of acute sinusitis.
