[Pharmacokinetics of cefotaxime during late pregnancy]

Examining serum level values and urinary concentrations taken from nonpregnant control persons and pregnant women suffering from urinary tract infections (UTI) during the third trimenon, the pharmacokinetic dates after single application of 1 g cefotaxime have been evaluated. We used a computer program based on the two-compartment model. It is shown that during pregnancy complicated by UTI the elimination half-life will be prolonged, the distribution volumes and clearance values will be increased. The results discussed with the dates given by literature allow us to state that it is not necessary to change dosage and application interval of cefotaxime during pregnancy.
