Hi ElMaestro,

» You have a difference in the absorbed fraction from the two formulations which screws everything up.

could you please explain what is happening here? Does it mean that changes in absorbed fraction did significantly modified PK of the drug? Are there any examples for another drugs where it was already observed?

» What is meant with this term??

Well, nothing special. I mean clearance does not depend on the route of administration for particular drug (or type of formulation).

But it seems to me that due to low absorption rate by time unit the PK properties of the analyte could be closer to some low dose IR (where non-linear kinetics rules). Is that correct?

Kind regards,
Mittyri
