Dear Helmut,

Thanks for your kind response and the clarification. I appreciate it. It helped me to focus more!

❝ In your original post you talked about an SR formulation. Locally applied, locally acting drugs (LALAs) are delayed release (DR). The correct model is simple (one or two compartments but with a substantial lag-time), which is not your current one.


Yes, I agree. Since the drug has major fraction absorbed in colon, I assumed it to be a SR formulation. But clearly in the plot, there is no significant lag time.

I believe, lag-time can be only observed in normal Conc-time plot. Isn't?

Thanks,
Titus
