Q
Vd =
A
amount of drug in the body/ plasma drug concentration
it is a VOLUME, remember that if they give you the actual amount of drug per kg in a patient
2
Q
t(1/2)=
A
(0.7 x Vd) / Cl
3
Q
Cl =
A
rate of elimination / plasma drug concentration
Vd x Ke (elimination constant)
(0.7 x Vd)/ t(1/2)
4
Q
Loading dose
A
(Cp x Vd)/ F
if IV F = 100%
5
Q
Maintenance Dose
A
(Cp x Cl)/F
if IV F = 100%
