The corresponding plasma concentration of drug is found to be 96 micrograms/ml. What is the volume of distribution of this drug? Please round to the nearest liter.
A 10 mg/Kg dose of a drug is given by intravenous injection to a 20 Kg dog. What would the volume of distribution be if the drug had been given orally and only 50% of the drug was absorbed (the concentration of drug at time = 0 is 0.1 mg/L)? Be sure to show your work.
