Cefuroxime: human pharmacokinetics

R D Foord

    Antimicrobial Agents and Chemotherapy
    |May 1, 1976
    PubMed
    Summary

    Cefuroxime, a new parenteral cephalosporin antibiotic, demonstrated favorable pharmacokinetics and safety in healthy males following intramuscular and intravenous administration. Measurable serum levels persisted for hours, with high urinary recovery and no adverse effects observed.

    Area of Science:

    • Pharmacology
    • Clinical Pharmacy
    • Antibiotic Research

    Background:

    • Cefuroxime is a novel parenteral cephalosporin antibiotic.
    • Understanding its pharmacokinetic and safety profile is crucial for clinical application.

    Purpose of the Study:

    • To evaluate the pharmacokinetics and tolerability of single doses of cefuroxime in healthy male volunteers.
    • To assess cefuroxime absorption, distribution, metabolism, and excretion following parenteral administration.

    Main Methods:

    • Single intramuscular and intravenous doses of cefuroxime (0.25-1.0 g) were administered to healthy male volunteers.
    • Serum concentrations, half-life, protein binding, distribution volume, and urinary recovery were measured.
    • Tolerability and adverse effects were assessed through physical and laboratory investigations.

    Main Results:

    • Peak serum concentrations increased with dose for both administration routes.
    • Mean serum half-life was 70 minutes, with 33% protein binding and >95% metabolic stability.
    • Urinary recovery was at least 95%, with 43-54% tubular secretion indicated by cefuroxime/creatinine clearance ratios.
    • No adverse effects were observed, and intramuscular injections were well tolerated.

    Conclusions:

    • Cefuroxime exhibits favorable pharmacokinetic properties and is well-tolerated following parenteral administration in healthy individuals.
    • The antibiotic is rapidly absorbed, widely distributed, and efficiently excreted, primarily via renal tubular secretion.
    • These findings support the potential clinical utility of cefuroxime as an effective parenteral antibiotic.
