Dear all,

the EMA requires multiple dose studies of prolonged release products if the mean AUCτ–∞ of both products after a single dose is >10% of AUC0–∞,1,2 whereas Health Canada was less restrictive (>20%).2,3 However, according to the current guidance of HC steady-state studies are not generally required.4

Discovered this goody about BE of extended release veterinary products:5,6,7

Kudos. Accumulation <2 (AUCτ–∞ <50% of AUC0–∞) is considered negligible. :thumb up:

and how to do it better, but many statisticians believe
it is a branch of mathematics.    George E.P. Box
