Question
Chapter 15.2, Problem 2CC
Summary Introduction
To explain: Whether the pressure waves occur simultaneously in a carotid artery and left wrist of a person.
Introduction: In the systemic circulation, more pressure begins in the aorta. This basically results from pressure formed by the left ventricle. The pressure in the aorta reaches an average of 120 mm Hg at the time of ventricular systole. This pressure then responsibly falls to a minimum of 80 mm Hg at the time of ventricular diastole.

- 3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.)
