“…One model [58] described the disposition of AMD and DEA in ponies and another one [59] was developed in humans. The pony PBPK model [58] consisted of limited number of tissue compartments, including blood, liver, kidney, fat, rapidly perfused tissues, and slowly perfused tissues. Although the human PBPK model [59] included more tissues, it may not provide insight into the kinetic behaviors of AMD in tissues since the predicted concentration-time profiles in most tissues cannot be evaluated due to the lack of observed data.…”
