JT is a 20 year old female on a continuous infusion of an antibiotic. The total dose that will be given is 1500 mg over 24 hours.

Expert Solution

A= C. Vd

here A= amount of the drug in the body

C = plasma concentration

Vd = volume of distribution of drug

1500mg= C. 69L

C= 1500mg/69L

C= 21.73mg/L

therefore plasma drug concentration in blood = 21.7mg/L
