βCL/F, βV1/F—scaling exponents for the apparent systemic clearance and apparent volume of the central compartment, respectively; BSV—between-subject variability; CL/F—apparent systemic clearance; ka—absorption rate constant; Q/F—apparent intercompartmental clearance; RSE—relative standard error; tlag—lag time; V1/F—apparent volume of the central compartment; V2/F—apparent volume of the peripheral compartment.
