1 Development of a pharmacokinetic model (using propofol as an example)
Development of a pharmacokinetic model (using propofol as an example). A. Raw data: Drug levels (red dots) are repeatedly measured over time. B. Analyzed data: A drug disposition curve (black line) is fit to the raw data using an exponential equation based on a computerized nonlinear regression analysis. C. The equation is simply a mathematical representation of curves of the general shape that “fit” the data. The nonlinear regression “curve-fitting” exercise results in a set of parameters (in this example, A, B, α, and β) that, when plugged into the equation, reproduce the curve through the data. Cp(t) represents the plasma propofol concentration as a function of time (t). This is the mathematical basis of the pharmacokinetic model that clinicians need not worry about.
