Hi,

I define the Cmin-Value in multiple dose bioequivalence studies as the 'Last concentration within the dosing interval'.

If the last value in the dosing interval is <LLOQ, which value should i use?

If i set the value to zero, the ratio T/R can't be calculated.
I can calculate a value <LLOQ (with the average half life time of the corresponding single dose study or the literature).
I can use the Last concentration value >=LLOQ (for both the reference and the test formulation)
I can use the Last concentration value >=LLOQ (for only one formulation, for the other i use the last concentration value).

thank you
