Subtopic 1: Pharmacology of Opioid
Analgesics
Question 1:
Which of the following opioid receptors is primarily responsible for the
analgesic and euphoric effects of morphine?
A. Delta
B. Kappa
C. Mu
D. Sigma
Rationale:
Mu receptors are the main target of most opioids, including morphine, and
are responsible for analgesia, euphoria, respiratory depression, and physical
dependence.
Question 2:
What is the mechanism of action of opioid analgesics?
A. Block cyclooxygenase enzymes
B. Inhibit reuptake of serotonin and norepinephrine
C. Bind to opioid receptors and inhibit pain transmission
D. Stimulate GABA release
Rationale:
Opioid analgesics bind to specific receptors (mu, kappa, delta) in the CNS,
altering the perception and response to pain.
Question 3:
, 3
Which of the following opioids is classified as a partial agonist?
A. Morphine
B. Fentanyl
C. Buprenorphine
D. Methadone
Rationale:
Buprenorphine is a partial agonist at the mu-opioid receptor and an
antagonist at the kappa receptor, offering analgesia with a ceiling effect on
respiratory depression.
Question 4:
Which opioid is considered the gold standard for comparison with other
opioids?
A. Codeine
B. Morphine
C. Hydromorphone
D. Oxycodone
Rationale:
Morphine is the standard opioid against which all others are compared due to
its long-standing use and well-established efficacy profile.
Question 5:
Which opioid has the fastest onset of action when administered
intravenously?
A. Morphine
B. Fentanyl
, 4
C. Hydrocodone
D. Tramadol
Rationale:
Fentanyl has a rapid onset due to its high lipid solubility, making it ideal for
acute pain or procedural sedation.
Question 6:
Tramadol differs from most opioids in that it also:
A. Antagonizes NMDA receptors
B. Inhibits serotonin and norepinephrine reuptake
C. Binds exclusively to delta receptors
D. Has a longer half-life than morphine
Rationale:
Tramadol has a dual mechanism—acting weakly at the mu-opioid receptor
and inhibiting serotonin/norepinephrine reuptake, making it unique among
opioids.
Question 7:
What is a major pharmacokinetic concern with codeine metabolism?
A. It is not metabolized by the liver
B. It bypasses first-pass metabolism
C. It requires CYP2D6 for conversion to morphine
D. It accumulates in adipose tissue
Rationale:
