    Area of Science:

    • Pharmacology
    • Pharmacokinetics
    • Computational Biology

    Background:

    • Maintaining stable plasma drug concentrations is crucial for effective and safe therapy.
    • Traditional dosing regimens may not account for individual pharmacokinetic variability.
    • Continuous optimization of drug delivery can improve therapeutic outcomes.

    Purpose of the Study:

    • To develop a computational program for calculating optimal intravenous drug doses.
    • To achieve and maintain constant plasma drug concentrations throughout a therapeutic course.
    • To personalize drug dosing based on individual pharmacokinetic parameters.

    Main Methods:

    • The program utilizes experimentally determined pharmacokinetic parameters (e.g., absorption rate constant, elimination rate constant).
