TOPIC 1: PHARMACOKINETICS AND PHARMACODYNAMICS
10 Questions • 11.6% of Exam • Examines the absorption, distribution, metabolism, and excretion of drugs along with their
mechanisms of action.
QUESTION 1
A drug exhibits nonlinear (capacity-limited) elimination characterized by
Michaelis-Menten kinetics. Which of the following statements best describes the effect
of increasing the dose from a low to a high level on the drug's clearance?
[A] Clearance remains constant because clearance is dose-independent.
[B] Clearance decreases as dose increases due to saturation of metabolic pathways.
[C] Clearance increases proportionally with dose because more drug is available for metabolism.
[D] Clearance first decreases then increases as dose surpasses the Km value.
Correct Answer: Clearance decreases as dose increases due to saturation of metabolic pathways.
Rationale: In Michaelis-Menten (capacity-limited) elimination, clearance (CL = Vmax/(Km + C)) declines as plasma
concentrations approach Vmax, reflecting saturation of the metabolizing enzymes.
QUESTION 2
A new antibiotic demonstrates time-dependent killing. Which PK/PD index is most
predictive of its clinical efficacy?
[A] Cmax/MIC
[B] AUC/MIC
[C] Time above MIC (T>MIC)
[D] Peak concentration to MIC ratio
Correct Answer: Time above MIC (T>MIC)
Rationale: Time-dependent antibiotics (e.g., β-lactams) exert maximal effect when plasma concentrations remain above the
MIC for a sufficient portion of the dosing interval; thus T>MIC is the key PK/PD index.

QUESTION 3
A drug with a half-life of 8 hours is administered intravenously as a continuous
infusion. After how many hours will the plasma concentration reach approximately 95%
of the steady-state concentration?
[A] 16 hours
[B] 24 hours
[C] 32 hours
[D] 40 hours
Correct Answer: 32 Hours.
Rationale: Steady state is generally achieved after ~4-5 half-lives. Four half-lives (4 × 8 h = 32 h) yields ~94% of steady
state; five half-lives (40 h) would be >95%, but 32 h is the closest answer.
QUESTION 4
When a prodrug undergoes extensive first-pass metabolism, which parameter is most
directly reduced, and how does this affect the drug's apparent clearance (CL/F)?
[A] Bioavailability (F) is reduced, causing an apparent increase in CL/F.
[B] Volume of distribution (Vd) is reduced, causing a decrease in CL/F.
[C] Intrinsic clearance (CLint) is reduced, causing a decrease in CL/F.
[D] Elimination half-life is reduced, causing an apparent increase in CL/F.
Correct Answer: Bioavailability (F) is reduced, causing an apparent increase in CL/F.
Rationale: First-pass metabolism lowers the fraction of dose reaching systemic circulation (F). Because CL/F =
Dose/(AUC), a lower F inflates the apparent clearance when calculated using oral data.
