Dear James

If you read our paper in European J. Med. Chem. 38 (2003) 233-243 you will
see that we have compared rat and human intestinal absorption data (%
absorbed). For 98 common drugs we find:

%Absorption(human) = 0.91 * %Absorption (rat) + 6.89
N = 98, R2 = 0.88, Sd = 11%, F = 675

Or if the fit is forced through the origin:

%Absorption(human) = 0.997 * %Absorption (rat)
N = 98, Sd = 11%, F = 640

We have a follow up paper that shows exactly how rat data can be used to
predict human data.

Best wishes

Michael H Abraham
