[Pharmacokinetics of cefuroxime in pregnant women with acute pyelonephritis].
The pharmacokinetics of cefuroxime was studied in 40 pregnant women with acute pyelonephritis. The women were in the 2nd and 3rd terms of pregnancy. The antibiotic was injected in a dose of 500 mg. The antibiotic levels in the blood and urine were determined with the agar diffusion method. The pharmacokinetic parameters were measured in a one-compartmental model with regard to antibiotic absorption. The measurement was performed with the use of computer. The cefuroxime concentrations in the blood and urine were practically the same at all periods of the study and at different terms of pregnancy. In pregnant women with acute pyelonephritis, the volume of cefuroxime distribution and the time of a two-fold decrease in the blood antibiotic levels increased. The estimation of the optimal scheme of cefuroxime dosing by the Krueger-Timer principles provided treatment of acute pyelonephritis in pregnant women with intramuscular injections of the antibiotic in a dose of 500 mg every 8 hours for 7-8 days.
