PHARMACOLOGY (VERIFIED AND
CORRECT Q & A) SATISFACTION
GUARANTEED 2026/2027
1. Which pharmacokinetic process is most significantly affected by the first-pass effect when
a drug is administered orally?
A. Distribution
B. Metabolism
C. Absorption
D. Excretion
Answer: B
Conceptual Explanation: The first-pass effect refers to the rapid hepatic metabolism of a
drug as it passes through the liver for the first time after absorption from the
gastrointestinal tract.
2. A drug has a high volume of distribution (Vd). What does this imply about the drug’s
location in the body?
A. It is confined to the plasma.
B. It is widely distributed into tissues.
,C. It is rapidly excreted by the kidneys.
D. It has high water solubility.
Answer: B
Conceptual Explanation: A large Vd indicates that the drug is extensively distributed into
peripheral tissues and is not limited to the vascular compartment.
3. When two drugs that are both highly protein-bound are administered simultaneously,
what is the most likely result?
A. The free fraction of one or both drugs may increase.
B. Both drugs will be excreted faster.
C. The drugs will become less toxic.
D. Absorption will be inhibited.
Answer: A
Conceptual Explanation: Competition for protein binding sites (like albumin) can lead to
displacement, increasing the concentration of free (active) drug in the plasma.
4. What is the primary site for drug metabolism in the human body?
A. Liver
B. Small Intestine
C. Kidneys
, D. Lungs
Answer: A
Conceptual Explanation: The liver is the primary organ responsible for drug metabolism,
utilizing various enzyme systems like CYP450.
5. Which type of drug binds to a receptor and produces the maximum possible response?
A. Partial Agonist
B. Antagonist
C. Inverse Agonist
D. Full Agonist
Answer: D
Conceptual Explanation: A full agonist binds to a receptor and mimics the endogenous
ligand to produce a 100% maximal biological response.
6. A patient is taking a drug that is a known inducer of the CYP3A4 enzyme. If they start a
second drug that is a substrate of CYP3A4, what will happen to the second drug?
A. Its plasma concentration will increase.
B. There will be no change.
C. Its half-life will lengthen.
D. Its plasma concentration will decrease.
