Renal insufficiency and fosfomycin

M Gobernado, J García, M Santos

    Chemotherapy
    |January 1, 1977
    PubMed
    Summary

    Fosfomycin serum levels and elimination times in patients with chronic kidney disease correlate with the severity of renal insufficiency. This impacts antibiotic dosing in patients undergoing dialysis.

    Area of Science:

    • Pharmacology
    • Nephrology
    • Infectious Diseases

    Background:

    • Fosfomycin is an antibiotic used for various infections.
    • Chronic renal insufficiency (CRI) can significantly alter drug pharmacokinetics.
    • Understanding fosfomycin's behavior in renal impairment is crucial for effective treatment.

    Purpose of the Study:

    • To investigate the serum levels and elimination kinetics of fosfomycin in adult patients with varying degrees of chronic renal insufficiency.
    • To assess the impact of periodical dialysis on fosfomycin pharmacokinetics.

    Main Methods:

    • Parenteral administration of 1g sodium salt of fosfomycin to eight adult patients with CRI.
    • Monitoring of serum antibiotic levels and elimination times.
    • Comparison of pharmacokinetic parameters based on the degree of renal insufficiency and dialysis status.

    Main Results:

    • Serum concentrations and elimination half-life of fosfomycin were directly related to the severity of renal impairment.
    • Patients undergoing periodical dialysis showed altered fosfomycin elimination patterns.
    • Significant correlation observed between renal insufficiency degree and fosfomycin serum levels and clearance.

    Conclusions:

    • The degree of renal insufficiency is a key determinant of fosfomycin serum levels and elimination.
    • Dosage adjustments for fosfomycin are necessary in patients with chronic kidney disease, especially those on dialysis.
    • Further studies are warranted to establish optimal dosing regimens for fosfomycin in renal impairment.
