Bioequivalence and Bioavailability Forum

Dear All,
I have some data of a single dose animal study of an Sustained release drug product such that its Cmax is attained with in 2 to 3 days. At certain pt. of time (say 25 day) conc. is below therapeutic value. Now my question is, Is there any software by which we can use this single dose data to predict Multiple dose data or any literature in this regard.

With best regards,
Ravi
