calc_total_clearance: Calculate the total clearance.

Description

This function calculates the total clearance rate for a one compartment model where clearance is entirely due to metablism by the liver and glomerular filtration in the kidneys, identical to clearance of three compartment steady state model.

Usage

calc_total_clearance(chem.cas=NULL,chem.name=NULL,parameters=NULL,species="Human", suppress.messages=F,default.to.human=F)

Arguments

chem.name
Either the chemical name, CAS number, or the parameters must be specified.
chem.cas
Either the chemical name, CAS number, or the parameters must be specified.
parameters
Chemical parameters from parameterize_steadystate function, overrides chem.name and chem.cas.
species
Species desired (either "Rat", "Rabbit", "Dog", "Mouse", or default "Human").

suppress.messages
Whether or not the output message is suppressed.
default.to.human
Substitutes missing animal values with human values if true.

Value

Total Clearance
Units of L/h/kg BW.

Details

When species is specified as rabbit, dog, or mouse, the function uses the appropriate physiological data(volumes and flows) but substitues human fraction unbound, partition coefficients, and intrinsic hepatic clearance.
