Hi jag009!

❝ I assume you are comparing AUC IR bid vs AUC CR in males.


Yes, you are right. I need to compare IR tablets 500 mg (2 times/day) and CR tablets 1000 mg (once a day).

❝ 1. Are the trough levels (or concentration at time 0 or time 24) between the IR bid and CR q.d. at steady state similar?


No. After steady state 14 days Cmin of IR tabl is 2600 ng/ml, Cmin of CR tabl is 1000 ng/ml. Tmax is 5 hours for both. The time-concentration profile has double peak.

Does it mean that CR tabl has specific absorption sites?

Thank you.

The difference between a surrogate and a true endpoint
is like the difference between a cheque and cash.
You can get the cheque earlier but then,
of course, it might bounce.    Stephen Senn
