title: [Clinical studies on te concentration of cefaclor in sera and lung tissues of patients with respiratory diseases].
abstract: A 500 mg dose of cefaclor (CCL) was administered orally before surgery to each of patients with respiratory diseases and in fasting. Average concentrations of CCL in sera were 4.04 micrograms/ml at 1.5 hours, 3.03 micrograms/ml at 2 hours, 1.68 microgram/ml at 3 hours and 0.45 microgram/ml at 5 hours after administration. Average concentrations in lung tissues during operation were 0.120 microgram/g at 3 hours, 0.272 microgram/g at 4 hours and 0.297 microgram/g at 5 hours after administration. Ratios of concentrations of CCL in lung tissues to that in sera were from 7.1 to 66.0 percent. The CCL was considered to be a useful antibiotic for the treatment of patients with respiratory diseases.
