Drug kinetics in pregnancy.

B Krauer, F Krauer

    Clinical Pharmacokinetics
    |May 1, 1977
    PubMed
    Summary

    All medications given to pregnant women can harm the fetus as they cross the placental barrier. Physiological changes in pregnancy affect drug absorption, distribution, and elimination, necessitating careful drug use and pharmacokinetic modeling.

    Area of Science:

    • Pharmacology
    • Obstetrics
    • Fetal Medicine

    Background:

    • All drugs administered to pregnant women can potentially harm the fetus due to placental transfer.
    • Pregnancy involves significant physiological alterations impacting drug pharmacokinetics.

    Purpose of the Study:

    • To review how physiological changes during pregnancy affect drug kinetics.
    • To explore the utility of pharmacokinetic models in predicting fetal drug exposure.

    Main Methods:

    • Review of physiological changes during pregnancy affecting drug absorption, distribution, and elimination.
    • Discussion of computerized pharmacokinetic models for fetal-maternal drug interrelationships.

    Main Results:

    • Pregnancy alters gastrointestinal, ventilatory, hemodynamic, and body water functions, influencing drug absorption and elimination.
    • Renal drug elimination is typically enhanced, while hepatic elimination varies.
    • Pharmacokinetic models can predict fetal drug exposure consequences.

    Conclusions:

    • Understanding drug kinetics in pregnancy is crucial for maternal and fetal safety.
    • Pharmacokinetic modeling offers valuable insights for managing drug therapy during pregnancy.
    • This knowledge aids in the clinical use of medications, especially for treating fetal conditions.
