Dear Helmut and other smart people!

Hey, you! Yes, you!

» Tricky – IMHO, case by case (should be laid down in an SOP or the SAP, of course). IIRC, Health Canada had a rule that 1 (one!) concentration is sufficient for Cmax and 3 (oh dear!) fo AUC. Gone with the wind. THX, HC.

Suppose we have only one measurable concentration and it is as high as Cmax of other periods. Even in this case formally we can calculate AUC for linear trapezoidal rule (depending on the rule for BLOQ data of course). And it can be more than 5 percent of geometric mean of other AUC in this period. Leave it or waste it - any choice will be wrong :no:
