I think the fed within subject variability chart is interesting: it shows the variability at the earlier time intervals in the fed state is huge and that makes the point very well. I am thinking that the food delays gastric emptying so the formulations are retained in the stomach ~ 3 hours prior to transiting to the small intestine. {would have thought that Concerta would be OK, since it has an IR overcoat component}.

I wonder how the within subject variability in the fasted state compares with the fed state for such formulations at the corresponding time intervals.
