IV Bolus Dosing Exercise

PLASMA DRUG CONCENTRATION EQUATION

At any time, the plasma drug concentration following administration by a single IV bolus is given by the equation below. Once you have found the parameters you can use this equation to calculate the plasma drug concentration at time t.
Equation

Dose = 100 mg
t1/2 = 4 hours
k = 0.173 h-1
AUC = 19.328 mgxh/L
CL = 5.174 L/h
Vd = 29.9 L
Example Question: What was the plasma concentration at 8.5 hours?
Type in your answer to two decimal places then press the OK button.
The plasma concentration was:   mg/L
