,Q1. Which pharmacogenetic polymorphism is most likely to result in a poor
metabolizer phenotype leading to increased risk of extrapyramidal symptoms when
treated with risperidone?
A. CYP2D6 gene duplication
B. CYP2D6 nonfunctional alleles
C. CYP3A4 poor metabolizer
D. CYP1A2 ultra-rapid metabolizer
Correct Answer: B. CYP2D6 nonfunctional alleles
Rationale: CYP2D6 is the primary enzyme metabolizing risperidone; nonfunctional alleles
result in poor metabolizer status, leading to elevated risperidone concentrations and
higher EPS risk. CYP2D6 duplication causes ultra-rapid metabolism, reducing efficacy.
CYP3A4 and CYP1A2 play minor roles in risperidone metabolism.
Why Wrong:
A - Gene duplication increases enzyme activity, lowering risperidone levels and EPS
risk.
C - CYP3A4 has a minor role in risperidone metabolism compared to CYP2D6.
D - CYP1A2 is not a major pathway for risperidone metabolism.

Q2. A patient on a stable dose of valproic acid is started on lamotrigine. Which
change in lamotrigine dosing is required to minimize the risk of Stevens-Johnson
syndrome?
A. Increase the lamotrigine dose by 50%
B. Decrease the lamotrigine dose by 50%
C. Maintain the standard titration schedule
D. Discontinue valproic acid immediately
Correct Answer: B. Decrease the lamotrigine dose by 50%
Rationale: Valproic acid inhibits lamotrigine glucuronidation, doubling its half-life. To
reduce SJS risk, lamotrigine dose should be halved when used with valproic acid.
Increasing the dose or standard titration would raise plasma levels dangerously.
Discontinuing valproic acid is not necessary and may be clinically inappropriate.
Why Wrong:
A - Increasing dose would further elevate lamotrigine levels, increasing SJS risk.
C - Standard titration does not account for the drug interaction and may lead to toxic
levels.
D - Valproic acid is often needed for the patient's condition; dose adjustment of
lamotrigine is preferred.

, Q3. Which of the following best explains the delayed onset of antidepressant efficacy
for SSRIs?
A. Monoamine depletion occurs during the first weeks of therapy
B. Downregulation of somatodendritic 5-HT1A autoreceptors is required
C. SSRIs initially increase GABAergic transmission, countering serotonin
D. Drug transport across the blood-brain barrier is gradual
Correct Answer: B. Downregulation of somatodendritic 5-HT1A autoreceptors is
required
Rationale: SSRIs block serotonin reuptake immediately, but clinical response requires
weeks, attributed to desensitization of 5-HT1A autoreceptors, enhancing serotonergic
neurotransmission. Monoamine depletion is not a mechanism of action. GABAergic
changes are not primary to SSRI action. Blood-brain barrier transport is not rate-limiting.
Why Wrong:
A - Monoamine depletion is a theory of depression, not a mechanism of delayed
effect.
C - SSRIs do not primarily affect GABAergic transmission.
D - SSRIs cross the blood-brain barrier readily; onset is not limited by transport.
Reference: Stahl, S.M. (2021). Stahl's Essential Psychopharmacology, 5th Ed., Ch. 6
Q4. Which of the following is the most appropriate initial intervention for a patient
presenting with neuroleptic malignant syndrome (NMS) during fluphenazine
therapy?
A. Increase fluphenazine dose to control psychosis
B. Administer bromocriptine and dantrolene immediately
C. Discontinue antipsychotic and provide supportive care
D. Switch to a second-generation antipsychotic without a washout period
Correct Answer: C. Discontinue antipsychotic and provide supportive care
Rationale: NMS is a medical emergency; first step is immediate discontinuation of the
offending antipsychotic and supportive measures (hydration, cooling). Bromocriptine and
dantrolene are adjunctive, not first-line. Increasing dose or switching without washout can
worsen NMS.
Why Wrong:
A - Increasing the dose exacerbates NMS.
B - These medications are used after discontinuation and supportive care.
D - Switching without washout risks continued NMS.
