    Summary
    This summary is machine-generated.

    Drug disposition, or how the body processes drugs, can reveal insights into liver function. This review explores using pharmacokinetic parameters like clearance to quantitatively assess liver health and disease progression.

    Area of Science:

    • Pharmacology
    • Hepatology
    • Drug Metabolism

    Background:

    • Liver disease significantly impacts drug disposition.
    • Drug disposition may serve as an indicator of hepatic function.
    • Understanding drug metabolism is key to assessing liver health.

    Purpose of the Study:

    • To review the physiological basis of drug disposition.
    • To explore pharmacokinetic parameters as indices of hepatic function.
    • To describe a quantitative approach for assessing liver function using drug disposition.

    Main Methods:

    • Review of physiological determinants of drug disposition.
    • Interpretation of pharmacokinetic parameters (half-life, clearance, intrinsic clearance).
    • Application of the 'intact hepatocyte hypothesis' model.

    Main Results:

    • Pharmacokinetic parameters offer insights into specific aspects of hepatic function.
    • Drug disposition of high and low intrinsic clearance drugs provides quantitative estimates.
    • The model estimates liver function, hepatocyte blood flow, and portasystemic shunting.

    Conclusions:

    • Theoretical frameworks exist for quantifying hepatic function via drug disposition.
    • Further clinical validation is needed to determine the utility of these indices in managing liver disease.
