The objective of this multicentre, randomised, open-label, general pra
ctice (GP) study was to evaluate the efficacy and tolerability of cefp
rozil (Cefzil(TM) Bristol-Myers Squibb) compared with that of cefuroxi
me axetil (Ceftin(R), Glaxo Wellcome) in the treatment of adult subjec
ts with acute sinusitis. Typical of the GP setting, diagnosis was made
based solely on clinical signs and symptoms of acute disease. Sinus r
adiography was performed post-randomisation. A total of 381 adolescent
and adult patients were randomly assigned to 10 days' treatment with
either cefprozil, 500mg orally twice daily (n = 191), or cefuroxime ax
etil, 250mg orally twice daily (n = 190). Based on predefined criteria
, treatments were found to be equally effective in terms of proportion
s of patients in the per-protocol population that were cured, improved
or failed (p = 0.20). Similar results were observed when the evaluati
on was performed on the subset of patients with radiographic evidence
of sinusitis and when the evaluation was based on the investigator's j
udgement. Similar rates of adverse events were observed in the two tre
atment groups. In summary, cefprozil 500mg twice daily is as well tole
rated and as effective as cefuroxime axetil 250mg twice daily for the
treatment of adolescent and adult patients with clinical signs and sym
ptoms of acute sinusitis.
