| Abstract: | Pharmacokinetics of 4 cephalosporanic antibiotics for parenteral use, i. e. cephaloridine, cephradine, cephazoline and cephacetryl was studied in surgical patients with normal function of the kidneys and liver. The first 3 drugs were well absorbed after intramuscular administration, their maximum serum levels being achieved during the first hour. High blood levels of cephacetryl were determined after its intravenous administration. When cephaloridine, cephradine and cephazoline were administered in equal doses, it was found that the first 2 drugs did not practically differ with respect to the values of the serum levels, the rate of elimination from the blood, the rate and level of excretion with the urine. Cephazoline was characterized by higher blood levels and slower elimination from the blood. |
