TLDR
The results of extensive analysis indicate that use of apparent or effective permeability rather than unbiased or true wall (membrane) permeability should generally suffice for prediction of or correlation with the fraction of oral dose absorbed after oral administration.
Intravenous verapamil kinetics in rats: Marked arteriovenous concentration difference and comparison with humans
TLDR
The plasma protein binding of verapamil in humans and rats were quite similar and constant over the wide concentration range studied and the potential shortcomings of using T1/2 or CLp and the advantage of using CLu (unbound plasma clearance) in interspecies scaling is also discussed.

TLDR
The present review probably represents the first of its kind ever reported in the literature, and it is hoped that the awareness of this very fundamental and important subject matter among readers, and may also stimulate further studies or discussions.
