model_flatAn object of class list (inherits from pk_model) of length 10.
A `pk_model` object: under the hood, a `list` object with elements corresponding to the arguments of [pk_model()]. See that function documentation for the definition of each element.
See [cp_flat()] for the function that predicts blood/plasma concentration for a bolus dose (oral or IV).
See [auc_flat()] for the function that predicts area under the concentration-time curve.
