Introduction To Pharmacokinetics

Single Short IV Infusion - k

A patient is given a single short IV infusion of 700 mg of a drug over a period of 7 hours.

You now know the following:
Elimination half-life (t1/2) = 0.5 hours

Now you know the elimination half-life, what is the elimination rate constant (k) of the drug?

Type in your answer to three decimal places then press the OK button.

The elimination rate constant is: h-1
