Back-calculates the Red Blood Cell to Unbound Plasma Partition Coefficient

Description

Given an observed ratio of chemical concentration in blood to plasma, this function calculates a Red Blood Cell to unbound plasma (Krbc2pu) partition coefficient that would be consistent with that observation.

Usage

calc_krbc2pu(
  Rb2p,
  Funbound.plasma,
  hematocrit = NULL,
  default.to.human = FALSE,
  species = "Human",
  suppress.messages = TRUE
)

Arguments

Rb2p

The chemical blood:plasma concentration ratop

Funbound.plasma

The free fraction of chemical in the presence of plasma protein Rblood2plasma.

hematocrit

Overwrites default hematocrit value in calculating Rblood2plasma.

default.to.human

Substitutes missing animal values with human values if true.

species

Species desired (either "Rat", "Rabbit", "Dog", "Mouse", or default "Human").

suppress.messages

Determine whether to display certain usage feedback.

Value

The red blood cell to unbound chemical in plasma partition coefficient.
