title: [Pulmonary diffusion of cefixime in man].
abstract: We measured the concentrations of cefixime in the human lung in vivo in order to evaluate indirectly the effectiveness of this antibiotic in the treatment of pulmonary infections. Twenty-three patients undergoing lung surgery entered the study and received cefixime either 200 mg 12-hourly (4 times) or 400 mg every 24 hours (twice). Blood samples and tissue specimens were collected simultaneously during surgery 4 or 8 hours after the last dose. Cefixime concentrations were measured by HPLC. The penetration of cefixime in both normal and neoplastic lung tissue was significant. Four or 8 hours after a 200 or 400 mg oral dose, lung concentrations were higher than the MIC90 values for sensitive strains and therefore consistent with effective therapeutic activity. The pharmacokinetics of cefixime in blood and in lung tissue suggest that pulmonary infections could be treated with a 400 mg dose once a day.
