B)first order
C)second order
D)third order

Question

Quizplus · Accepted Answer

First order kinetics is characterized by a rate of elimination that is proportional to the concentration of the drug in the plasma (in log units). This means that as the concentration of the drug decreases, the rate of elimination also decreases, resulting in an exponential decay of drug concentration over time. Zero order kinetics, on the other hand, is characterized by a constant rate of elimination, regardless of the concentration of the drug in the plasma. Second and third order kinetics describe more complex processes that are not typically observed in drug metabolism.
