  • 1.  Computing Language for PK/PD.

    Posted 11-22-2022 13:25
    Hello dear Colleges, I believe that R is the most commonly used language for PK/PD outcomes computing. that what I were able to reach through my search till now. would you agree to that. if yes. is there a way to learn the use of the computing program on my own?

    Hi Ahmed

    I'm not sure if R is the most commonly used language for PK/PD modelling. But if you wish to learn the concepts and applications of PK/PD modelling the following books are the classical books in this area:

    Pharmacokinetic and Pharmacodynamic Data Analysis: Concepts and Applications, by Gabrielsson and Weiner (there are lots of code samples in this book)

    Clinical Pharmacokinetics and Pharmacodynamics: Concepts and Applications Malcolm Rowland and Thomas N. Tozer

    Hope this helps.

    Regards
    Masoud

    Hi Ahmed,
    R can be used, however R is mainly used, obviously, for popPK and not simply for PK, being R fundamentally a statistic software.
    Some popPK software's are based on R even if it's not easily appreciable by software interface (i.e. there is no clear evidence of R running underground), since they include a compiler, i.e. a user-friendly interface, or a graphic interface for allowing to write write differential equations and R codes to non-R expert users.
    However, one of most used PK/PD software is Phoenix WinNonlin (Certara) where, for example, you can write codes by yourself or  Gabrielsson and Weiner book codes can be directly applied.

    The issue with R - like all the relatively new open-source SW - is that you need a strong and centralized consortium to establish which algorithms are most solid and how the validation & verification should be carried out. One may argue that building with MATLAB might have a similar issue, however we all trust ODE solver and fitting algorithms there. I am not saying that R is untrustworthy, on the contrary, there can be more sparkle for innovation there, but it is you add an additional layer of checks and getting together to establish standards. Maybe we will get there, so it is with investing time now and Academia should do carry the load.
    On the other hand, established sw are more convenient considering the time-cost ratio you'll have in the long run. 
    Another point, and perhaps a myth, is that there is no software that does everything great from preclinic to the clinic to market!
    For a list of software refer to: https://www.page-meeting.org/default.asp?alias=912

    My humble opinion is (depends on the area of modeling you want to do though):
    >PK & popPK>: Phoenix/Nonmem/monolix
    >PBPK> simcyp/pk sim(free)/gastroplus
    >complex PK/PD > SAAM II
