Arguments

perp

The perpetrator object.

cyp_inh

CYP inhibition data as data frame. The following fields are expected:

  • 'name' The name of the perpetrator compound.

  • 'cyp' The CYP enzyme as (upper case) character.

  • 'ki' The \(K_i\) in \(\mu M\) as numeric.

  • 'source' Optional source information as character.

cyp_tdi

The CYP TDI data as data frame. The following fields are expected:

  • 'name' The perpetrator compound name as character.

  • 'cyp' The CYP enzyme as character.

  • 'ki' The \(K_I\) in \(\mu M\) as numeric.

  • 'kinact' The \(k_{inact}\) in 1/h as numeric.

  • 'source' Optional source information as character,

cyp_ind

The CYP induction data as data frame. The following fields are expected:

  • 'name' The name of the perpetrator compound as character.

  • 'cyp' The CYP enzyme as (upper case) character.

  • 'emax' The \(E_{max}\), i.e., the maximum induction effect determined in vitro as numeric.

  • 'ec50' The \(EC_{50}\) in \(\mu M\) as numeric.

  • 'maxc' The maximal concentration in \(\mu M\) tested in the in vitro assay as numeric.

  • 'source' Optional source information as character.

ugt_inh

UGT inhibition data as data frame, The following fields are expected:

  • 'name' The name of the perpetrator compound.

  • 'ugt' The UGT enzyme as (upper case) character.

  • 'ic50' The \(IC_{50}\) in \(\mu M\) as numeric.

  • 'source' Optional source information as character.

transporter_inh

Transporter inhibition data as data frame. The following fields are expected:

  • 'name' The perpetrator compound name.

  • 'cyp' The UGT enzyme as (upper case) character.

  • 'ic50' The \(IC_{50}\) of the inhibition in μM.

  • 'source' Optional source information as character.

d

Scaling factor, defaults to 1.

include_induction

Switch to define whether induction effects should be included in the calculation (C-terms as per the FDA guideline)

substr

The CYP probe substrates to be used as data frame, defaults to cyp_reference_substrates. The data frame is expected to have the following fields:

  • 'cyp' The CYP enzyme as (upper case) character.

  • 'substrate' The substrate name as character.

  • 'fgut' The fraction of the drug escaping gut metabolism.

  • 'fm' The fraction of the drug that undergoes hepatic metabolism.

  • 'fmcyp' The fraction metabolized by the respective CYP enzyme.

cyp_kdeg

The CYP turnover data as data frame. Defaults to the built-in reference data, cyp_turnover.

Value
