Dear K@K
Regarding 6.1: I guess the Russian guidance refers to something like partialAUC.
What do you think about this parameter?:

partialAUC_{(0-Tmax)+(Tmax-T75%Cmax)}

Regarding 6.2, IMHO it does not make sense for an individual PK parameter to have a reference to mean values. So I agree, this is very confusing. Partial AUC without initial absorption phase until mean steady state concentration is reached until decline after Tmax to individual 75%Cmax values? This does not make sense, right?
Kind regards
Dan
