You know, to drug development understanding PKPD is important.
I’m not DMPK dept. but I think it’s better to know about basic PKPD theory.
There are some packages about pkpd analysis in R.
And I found cool library developed ronkeiser named “PKPDsim”.
This library can integrate shiny, so user can calculate PKPD on the fly!
I used the library today.
I following code is almost same as document.
Following code is simulation of 1 compartment model, oral dose.
pk_1cmt_oral is defined in source code.
library("PKPDsim") library("ggplot2") p <- list(CL=1, V=10, KA=0.5) pk1 <- new_ode_model("pk_1cmt_oral") r1 <- new_regimen( amt=100, times=c(0,12,24,36) ) dat <- sim_ode(ode = "pk1", par = p, regimen=r1 ) plt <- ggplot( dat, aes(x=t, y=y) ) + geom_line() + facet_wrap(~comp) print(plt)
Then run shiny, and simulate on the fly.
sim_ode_shiny(ode='pk1', par=p, regimen=r1)
I think it’s good library to study or simulate PKPD.
