Gordi,
I've used pop-pk for toxicokinetic studies for both dogs and rats. This
approach has been used predominantly where data was censored (BQL) in some
animals at late time points. The population method correctly uses all of
the data without imputation and will, in general provide a more accurate
(higher) estimate of AUC(0-inf).
These analyses were not done prospectively.
Do bear in mind that the variability is likely to be low, even in six
subjects, and certainly lower than you will be used to in humans.
Kind regards,
Daren
