Example PK Model for Sensitivity Analysis

Source: R/models.R

The example PK model that were used in sensitivity testing. Three examples are included: Flip-flop pharmacokinetic model, one-compartment toxicokinetic model from httk (Pearce et al. 2017), and acetaminophen pharmacokinetic model (Zurlinden et al. 2016).

FFPK(params, time, dose = 1)

pbtk1cpt_model()

pbpk_apap_model()

Arguments

params

a numeric vector to define the input parameter value.

time

a numeric vector to define the given time point(s).

dose

a numeric value to define the given dose in flip-flop model.

Functions

  • pbtk1cpt_model(): Download pbtk1cpt.model file.

  • pbpk_apap_model(): Download pbpk_apap.model file.
