Hi mittyri!

❝ According russian guide t_75% is calculated (chapter 6.1).

❝ So the question is: what can we do with this data?

❝ As you can see in chapter 7 (Statistical evaluation of bioequivalence) this parameter isn't used.

Interesting, didn’t notice that before! Chapter 6.1 and 6.2 calls for the T/R ratios of these PK metrics and Chapter 7 calls for BE assessment of AUC_t or AUC_∞ (AUC_τ,ss if applicable), C_max, C_max/AUC_t, C_max/AUC_∞ (or C_max/AUC_τ,ss).

❝ Would you explain this issue?

Your are closer to Russian regulators than I am. Duno, ask them. I would say simply report t_75% etc.
