Allometric scaling equations applied

Parameter Abbreviation Unit Allometric Scaling
Volume of distribution (central compartment) V2 L V2 = θV2· (BW/25)1
Clearance CL L/hour CL = CL(t) · (BW/25)0.75
CL(t)=CLbase+CLmax(1eCLtau*Age)
Oral absorption rate constant KA 1/hour KA = KA(t)
KA(t)=KAbase+KAmax(1eKAtau*Age)
Volume of distribution (peripheral compartment) V3 L V3 = θV3· (BW/25)1
Inter-compartment clearance Q L/hour CL = θQ·(BW/25)0.75

BW: Body weight in kg
