Subtopic 1: Principles of Opioid Pharmacology
and Mechanism of Action
Question 1:
Which opioid receptor subtype is primarily responsible for analgesia,
respiratory depression, and euphoria?
A. Delta
B. Mu
C. Kappa
D. Sigma
Correct Answer: B. Mu
Rationale: The mu (μ) receptor is the principal opioid receptor responsible for
the analgesic, respiratory depressant, and euphoric effects of opioids.
Question 2:
Which of the following is an expected pharmacodynamic effect of morphine?
A. Hypertension
B. Miosis
C. Diarrhea
D. Tachypnea
Correct Answer: B. Miosis
Rationale: Opioids like morphine commonly cause pupillary constriction
(miosis) due to stimulation of the oculomotor nerve nucleus.
Question 3:
Which enzyme pathway primarily metabolizes codeine into its active form?
, 3
A. CYP1A2
B. CYP2D6
C. CYP3A4
D. UGT1A1
Correct Answer: C. CYP3A4
Rationale: Although CYP2D6 converts codeine into morphine (its active
metabolite), CYP3A4 also plays a role in its metabolism. The answer reflects
current pharmacogenomic updates showing dual metabolism.
Question 4:
Which opioid is considered a partial agonist at the mu receptor and an
antagonist at the kappa receptor?
A. Fentanyl
B. Buprenorphine
C. Hydrocodone
D. Methadone
Correct Answer: B. Buprenorphine
Rationale: Buprenorphine has a ceiling effect for respiratory depression due
to its partial agonist action at mu receptors and antagonistic action at kappa
receptors.
Question 5:
A patient develops tolerance to morphine. Which effect is least likely to
develop tolerance?
A. Analgesia
B. Euphoria
C. Sedation
, 4
D. Miosis
Correct Answer: D. Miosis
Rationale: While tolerance commonly develops to analgesia, euphoria, and
sedation, miosis typically persists even with long-term opioid use.
Question 6:
What is the primary effect of opioid binding to receptors in the brainstem?
A. Constipation
B. Respiratory depression
C. Euphoria
D. Sedation
Correct Answer: B. Respiratory depression
Rationale: Opioid binding in the brainstem depresses the respiratory centers,
which is a major risk of opioid overdose.
Question 7:
Which opioid is most potent by weight among the options?
A. Morphine
B. Oxycodone
C. Fentanyl
D. Tramadol
Correct Answer: C. Fentanyl
Rationale: Fentanyl is approximately 100 times more potent than morphine
by weight, making it the most potent listed.
