Multiple Choice Questions (MCQs)
Which enzyme primarily metabolizes most benzodiazepines in the liver?
A) CYP3A4
B) CYP2D6
C) CYP1A2
D) CYP2C9
Answer: A) CYP3A4
Rationale: : Benzodiazepines like midazolam and diazepam are mainly
metabolized by CYP3A4, making interactions with CYP3A4 inhibitors
clinically significant.
Which of the following drugs is considered a narrow therapeutic index
medication requiring close plasma level monitoring?
A) Digoxin
B) Metoprolol
C) Lisinopril
D) Furosemide

Rationale: : Digoxin has a narrow therapeutic window; subtherapeutic
or toxic levels can cause severe complications.
What is the mechanism of action of the drug class known as proton pump
inhibitors (PPIs)?

, D) Neutralize gastric acid
Answer: C) Inhibit H+/K+ ATPase pump in gastric parietal cells
Rationale: : PPIs irreversibly inhibit the H+/K+ ATPase pump, reducing
gastric acid secretion.
