RESUMEN
Levels of cefuroxime in bronchial secretion were measured in 49 patients requiring bronchoscopy for diagnostic purposes. Patients were randomly allocated to one of 4 groups which differed with respect to the size (750 mg or 1.5 g) and number (1 or 7) of intravenous doses of cefuroxime given approximately 1 hour prior to sampling. Levels of cefuroxime achieved after administration of all 4 dosages were sufficient to exceed the MIC values for the major chest pathogens. Penetration of cefuroxime into bronchial secretion was also found to be dose-related.

Cefuroxime is a new parenteral antibiotic with a wider spectrum of activity than earlier cephalosporins and is particularly active against Haemophilus influenzae, including strains resistant to ampicillin due to beta-lactamase production. From 18 centres, 274 patients suffering with 275 infections were treated with cefuroxime sodium using the standard regimen of 750 mg 8-hourly by intramuscular injection. The clinical results showed a 90% success rate in the patients with bronchopneumonia (105), 91% in patients with post-operative pneumonia (74), and 89% in the patients with acute exacerbations of chronic bronchitis (96). Renal function was closely monitored during therapy, and no adverse changes attributable to cefuroxime therapy were seen in any patient, including those who also received frusemide. Two patients (0.7%) developed a rash, although 8 penicillin-allergic patients were treated without incident. From these studies, it can be concluded that 750 mg cefuroxime 8-hourly is effective in the treatment of lower respiratory tract infections. It is suggested that the attributes of this antibiotic may offer several advantages over existing therapies.
