[Iteration program for determining pharmacokinetic constants with a digital computer (author's transl)].

P W Lücker

    Arzneimittel-Forschung
    |January 1, 1977
    PubMed
    Summary

    A new iteration program precisely determines kinetic constants k1 and y0 using graphical data. This method enhances Bateman function accuracy and reduces the need for blood sampling during analysis.

    • To enable precise calculation of constants using graphical parameters (tmax, k2).
    • To improve the definition of the Bateman function through accurate constant determination.

    Summary:

    • An iteration program for the HP 97 desk calculator is described.
    • The program accurately determines kinetic constants k1 and y0 from graphical constants tmax and k2.
