SOLUTION: chemistry

PROBLEM: Question: Which of the following statements about the steady-state infusion of a drug is true?
Options: <0> The concentration reached in steady state of equilibrium depends exclusively on the clearance. <1> The time necessary to reach the steady state of equilibrium depends on the volume of distribution. <2> The concentration reached in a steady state depends exclusively on the elimination half-life. <3> The concentration achieved in the steady state equilibrium depends on the clearance and the infusion rate. <4> The time required to reach the steady state of equilibrium depends on the clearance.

SOLUTION: pharmacology
