PHARMACOKINETIC STUDY OF CEFUROXIME / 中国药理学通报

ABSTRACT

Clinical pharmacological study of cefuroxime was carried out in 8 normal volunteers. The drug obeyed two-compartment model kinetics in serum. The mean peak serum concentrations were 32.14, 89.06 and 63.11 (.is/ml respectively after IM, IV injection and IV infusion of 0.75g cefuroxime. Serum concentrations after IV administration dec re- ased rapidly, the elimination half lives ranged from 1.05-1.48 hours Absorption after IM injection was rapid and complete, the bioava-ilability being 98.89%,The apparent volume of distribution. ranged from 0.34 L/kg to 0.37 L/kg after IM and IV administration which showed that cefuroxime distributed mainly in extracellular fluid.The mean urinary recovery of cefuroxime was more than 90% within 24 hours after the administration of the drug.Based on its pha.rmacokinetic characteristics and antimicrobial activity, a therapeutic regimen is suggested for use in the treatment of various infections.
