A patient is administered a drug through IV infusion at a rate of 300 mg/h. The drug is eliminated from the body via urine and the halflife is reported as 5h. Based on the patient’s weight, you are expecting a steady-state level of 7 mg/ml. A) Based on these assumptions, how much is Vd? B) A blood test shows that the concentration of the drug in the plasma is 15 mg/ml. Looking at your assumptions, what might have been wrong?...
