,Pharmacokinetics & Pharmacodynamics (6 Questions)
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
When calculating the steady-state volume of distribution (Vd) for a highly lipophilic drug that
extensively binds to tissue proteins, which of the following equations provides the most
accurate estimate?
A. Vd = (Dose × F) / (Cmax × Bioavailability)
B. Vd = (Dose × F) / (AUC0‑∞)
C. Vd = (Dose × F) / (Cl × τ)
D. Vd = (Dose × F) / (Cmin × τ)
Correct Answer
Vd = (Dose × F) / (AUC0‑∞)
Rationale:
For a drug at steady state, Vd can be derived from the relationship Vd = (Dose × F) / (AUC), where AUC reflects
total systemic exposure, accounting for extensive tissue binding.

,Question 3
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 4
In a population pharmacokinetic (PopPK) analysis using NONMEM, which of the following
statements best describes the purpose of the η (eta) parameter?
A. It represents inter‑occasion variability in the residual error model.
B. It quantifies the random between‑subject variability for a structural PK parameter.
C. It is the fixed effect estimate for the typical population value of a parameter.
D. It denotes the covariate effect of body weight on clearance.
Correct Answer
It quantifies the random between‑subject variability for a structural PK parameter.
Rationale:
In PopPK models, η describes the deviation of an individual's parameter from the typical population value, capturing
inter‑subject variability.

, Question 5
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 6
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.
