UNLABELLED: The concentrations of cefodizime (HR 221, CAS 69739-16-8) in bronchial secretions were measured after administration of a single intravenous bolus of 2 g in 19 patients requiring fibreoptic bronchoscopy for diagnostic purposes or as therapeutic follow-up. These concentrations, which were obtained in absence of inflammation of the mucosa, were compared to serum concentrations obtained simultaneously. The penetration into bronchial secretions was rapid, maximum levels of between 1 and 5 mg/kg being already observed 1 h after injection. Most concentrations remained about 1 mg/kg throughout the whole observation period of about 5.5 h. The percent penetration amounted to about 1.5% of the corresponding serum concentrations. CONCLUSION: Concentrations well above the MIC90s of the relevant respiratory pathogens--S. pneumoniae, M. catarrhalis, H. influenzae, K. pneumoniae--and Enterobacteriaceae were reached in bronchial secretions after intravenous injection of a single 2 g dose of cefodizime. Even higher levels may be expected in the usual condition of inflamed bronchial mucosa as found in respiratory infections.
