I initially tried parametrization in terms of CL and V realizing they are meaningful parameters but I dont know for what reason it didnt work even after fixing KA to different values and I had underpredicted concentrations all over the data. I am using method=0 (FO). By the way the data I have is rich so please advice if FO or FOCE would be appropriate. Thanks MK
