title: Clinical comparison of cefuroxime axetil and amoxicillin/clavulanate in the treatment of patients with acute bacterial maxillary sinusitis.
abstract: OBJECTIVE
  This multicenter study compared the clinical and bacteriologic efficacy of two oral antibiotics, cefuroxime axetil and amoxicillin/clavulanate, in the treatment of acute bacterial maxillary sinusitis.
  
  
  METHODS
  Three hundred seventeen patients with clinical and radiographic evidence of acute maxillary sinusitis were enrolled at nine centers and were randomly assigned to receive 10 days of treatment with cefuroxime axetil 250 mg twice daily (n = 157) or amoxicillin/clavulanate 500 mg three times daily (n = 160). Patients were assessed for both clinical and bacteriologic responses once during treatment (5 to 7 days) and twice after treatment (1 to 3 days and 4 weeks). Bacteriologic assessments were based on needle aspirates of the maxillary sinus obtained pretreatment and, when possible, at the first posttreatment visit.
  
  
  RESULTS
  Organisms were isolated from the pretreatment sinus aspirates of 198 of 317 (62%) patients, with the primary isolates being Streptococcus pneumoniae (22%), Haemophilus spp. (17%), Staphylococcus aureus (13%), and Haemophilus influenzae (10%). A satisfactory clinical outcome (cure or improvement) was achieved in 85% (98 of 115) and 82% (102 of 124) of the clinically evaluable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (P = 0.446). With respect to the eradication of the bacterial pathogens, a satisfactory outcome (cure or presumed cure) was obtained in 84% (31 of 37) and 87% (34 of 39) of bacteriologically evaluable patients treated with cefuroxime axetil or amoxicillin/clavulanate, respectively (p = 0.567). Treatment with amoxicillin/clavulanate was associated with a significantly higher incidence of drug-related adverse events (13% versus 3%, p = 0.001), particularly diarrhea (8% versus 1%, p = 0.001). Two patients in the cefuroxime axetil group and three patients in the amoxicillin/clavulanate group withdrew from the study due to adverse events.
  
  
  CONCLUSIONS
  Our results indicate that cefuroxime axetil twice a day is as effective as amoxicillin/clavulanate three times a day in the treatment of acute bacterial maxillary sinusitis but produces fewer adverse effects.
