New trends in aminoglycoside dosing

C M Kuharcik, A C Craig

    ANNA Journal
    |December 1, 1994
    PubMed
    Summary

    Once daily dosing of aminoglycoside antibiotics offers equal efficacy to traditional thrice daily regimens. This approach reduces toxicity and costs while ensuring therapeutic serum concentrations for serious gram-negative infections.

    Area of Science:

    • Pharmacology
    • Infectious Diseases
    • Clinical Pharmacy

    Background:

    • Aminoglycosides are critical for treating serious aerobic gram-negative infections.
    • Traditional dosing regimens can lead to significant toxicities.
    • Optimizing aminoglycoside therapy is essential for patient outcomes.

    Purpose of the Study:

    • To evaluate the efficacy and advantages of once daily aminoglycoside dosing.
    • To compare once daily dosing with traditional thrice daily dosing.
    • To explore the impact of dosing strategies on aminoglycoside toxicity and cost-effectiveness.

    Main Methods:

    • Clinical trials comparing single daily dosing to thrice daily dosing of aminoglycosides.
    • Analysis of pharmacokinetic and pharmacodynamic properties, including post-antibiotic effect (PAE) and concentration-dependent bactericidal activity.
    • Assessment of clinical efficacy, ototoxicity, nephrotoxicity, and administration-related factors.

    Main Results:

    • Once daily dosing demonstrated equal efficacy to thrice daily dosing in clinical trials.
    • This dosing strategy leverages PAE and concentration-dependent killing.
    • Projected benefits include reduced ototoxicity and nephrotoxicity, guaranteed therapeutic peak concentrations, and improved administration efficiency.

    Conclusions:

    • Once daily aminoglycoside dosing is a safe and effective alternative to traditional regimens.
    • This approach offers significant advantages in terms of toxicity reduction, cost-effectiveness, and patient management.
    • Optimized dosing strategies enhance the therapeutic utility of aminoglycosides for serious infections.
