Chapter 44, Problem 3ITD

Nifedipine is an antihypertension medication that is also used to reduce the workload on the heart. The study below compares the effects of two different types of capsules used to administer the drug to patients (GITS—red line, and Cotracten X—blue line). Each graph shows changes with time following initial administra- tion of the capsules. Figure A compares the levels of nifedipine in the blood with each capsule type. The ability of the different cap- sules to reduce workload on the heart by altering blood pressure or heart rate is shown in Figures B and C, respectively.

Coumadin is an anticoagulant drug that is sometimes given to patients who have just suffered a deep vein thrombosis, a pulmonary embolism, a heart attack, or to patients with artificial heart valves. It helps reduce the chance of future clots and the further risk of embolism. The active ingredient in Coumadin is warfarin, a rat poison. How do you think the same compound can be used for these two very different purposes?
200 mg of drug is given IV, plasma drug concentration is 70 mg/L. Calculate the Vd? Where most of the drug is distributed to? Note: Volume of Distribution (L) = Amount of drug in the body (mg) / Plasma concentration of drug (mg/L). O a. Vd=14000 L, drug is mostly outside of plasma, distributed to tissues O b. Vd=2.8 L, drug is mostly outside of plasma, distributed to tissues OC. Vd =0.35 L, drug is mostly in plasma Od. Vd=2.8 L, drug is mostly in plasma O e. Vd =0.35 L, drug is mostly outside of plasma, distributed to tissues
