Dear mittyri and Elmaestro,

If we re-arrange the equation of Vss = (dosepo x F x AUMC0-infinity) / AUC20-infinity as Vss/F = (dosepo x AUMC0-infinity) / AUC20-infinity. For extravascular dosing, we only can calculate Vc/F, Vss/F, or Cl/F.

❝ ... we need to know MIT,..., tlag and ka


No need to know MIT (or tlag and ka). Again we can also re-arrange Vss = (F x Dose/AUC0-infinity)x MRT as Vss/F = (Dose/AUC0-infinity)x MRT = Cl x MRT.

We can get the values of all parameters (Dose, AUC0-infinity, AUMC0-infinity and MRT) on the right-hand sided both equations after NCA. So I wonder why we can not calculate Vss.

All the best,
