All pk models have two extravascular dosing compartments and potential for linear and nonlinear clearance.
pk1cmt
: one compartment pk model
pk2cmt
: two compartment pk model
pk3cmt
: three compartment pk model
See modlib_details
for more detailed descriptions of parameters and compartments.
The pk1cmt
model is parameterized in terms of CL
, VC
, KA1
and KA2
and uses compartments EV1
,
EV2
, and CENT
. The pk2cmt
model adds a PERIPH
compartment and parameters Q
and VP
to that of the
one-compartment model. Likewise, the three-compartment model (pk3cmt
) adds PERIPH2
and parameters Q2
and VP2
to
that of the two-compartment models. All pk models also have parameters VMAX
(defaulting to zero, no non-linear clearance) and KM
.
