Hi Imph,

❝ Is it right to do "7 x t1/2 mean" without taking into consideration the SD?


That’s extremely risky. You may see residual concentrations in subjects with a half life longer than the reported mean and have to exclude them to avoid carryover (i.e., if the predose concentration is >5% Cmax).

See this presentation (slides 64/65).
