Pharmacokinetics in clinical practice. I. Concepts

M Gibaldi, G Levy

    JAMA
    |April 26, 1976
    PubMed
    Summary

    Pharmacokinetic concepts like half-life and clearance help predict drug levels in the body. These principles quantify patient individuality, including disease effects on drug absorption, distribution, metabolism, and excretion.

    Area of Science:

    • Pharmacology
    • Clinical Pharmacy

    Background:

    • Pharmacokinetics describes how the body affects a drug.
    • Key parameters include biologic half-life, clearance, and bioavailability.

    Purpose of the Study:

    • To explain the utility of pharmacokinetic concepts.
    • To demonstrate their role in predicting drug concentrations and patient variability.

    Main Methods:

    • Utilizing established pharmacokinetic principles.
    • Applying quantitative analysis to drug disposition.

    Main Results:

    • Pharmacokinetic parameters accurately describe drug concentration over time.
    • These parameters quantify patient-specific factors influencing drug disposition.

    Conclusions:

    • Biologic half-life, clearance, and bioavailability are essential for understanding drug behavior.
    • Pharmacokinetics enables personalized drug therapy by accounting for individual patient characteristics and disease states.
