Hi,

Thank you very much for your valuable informations.

I would like to know if this method can be applied to each pharmacokinetic measurement, for example to determine the duration of the sampling (5 x t1/2) or to calculate the predose limit of 5% Cmax when the Cmax is provided in the literature under mean+/-SD.

Why plan for 95% coverage (z0.95 = 1.96), is it related to alpha =5%.

In the reference you gave, a normal distribution is assumed, but pharmacokinetic measurements do not generally follow a normal distribution but a log-normal one. Does this method still apply?

Thank you verry much.
