Question 1
A drug is administered as an oral tablet and the same dose is given intravenously. The ratio of the area under the plasma concentration-time curve (AUC) after oral administration to the AUC after IV administration is 0.40. What does this value represent?
Correct Answer:
The absolute bioavailability of the oral product
Question 2
A drug follows first-order elimination with a half-life of 8 hours. Approximately how long will it take to reach steady state during a constant-rate infusion or repeated dosing at a fixed interval?
Correct Answer:
About 40 hours
Question 3
A weakly acidic drug has a pKa of 4. At gastric pH of approximately 2, which statement about its ionization and membrane permeability is most accurate?
Correct Answer:
It is mostly un-ionized, favouring passive diffusion across lipid membranes relative to the ionized form
Question 4
A pharmacist is reviewing a sustained-release matrix tablet. Which statement best describes the primary rationale for a sustained-release dosage form?
Correct Answer:
To reduce dosing frequency and minimize peak-trough fluctuations
Question 5
Warfarin is highly protein-bound (~99%). A patient is started on a second drug that displaces warfarin from albumin. What is the most accurate description of the clinical consequence at new steady state for a low-extraction drug?
Correct Answer:
A transient rise in free fraction, but total clearance of free drug increases so free concentration tends to return toward baseline
