Description: This comprehensive set of 200 multiple-choice questions (MCQs) with
answers and rationales is designed for revision of NR546 Advanced Pharmacology:
Psychopharmacology. It covers key concepts including neurotransmitters,
pharmacokinetics, pharmacodynamics, psychotropic drug classes (antidepressants,
antipsychotics, mood stabilizers, anxiolytics, hypnotics, stimulants), adverse
effects, drug interactions, and clinical applications across the lifespan. Each question
includes the correct answer marked with ✅ and a concise rationale to reinforce
learning.
Keywords: NR546, NR 546, Advanced Pharmacology, Psychopharmacology, Midterm,
Final Exam, Chamberlain, Study Guide, MCQs, Antidepressants, Antipsychotics, Mood
Stabilizers, Anxiolytics, ADHD, Neurotransmitters, CYP450, Serotonin Syndrome,
Neuroleptic Malignant Syndrome, Bipolar Disorder, Schizophrenia, Depression, Anxiety,
Insomnia, Substance Use, Geriatric Psychopharmacology, Pediatric
Psychopharmacology.
,1–25: Neurotransmitters & Basic Principles
1. Which neurotransmitter is primarily implicated in the pathophysiology of
schizophrenia?
A. Serotonin
B. Dopamine ✅
C. GABA
D. Acetylcholine
Rationale: The dopamine hypothesis suggests hyperactivity of mesolimbic dopamine
D2 pathways contributes to positive symptoms.
2. Which neurotransmitter is most associated with anxiety disorders?
A. Dopamine
B. GABA ✅
C. Glutamate
D. Histamine
Rationale: GABA is the major inhibitory neurotransmitter; reduced GABA activity is
linked to anxiety.
3. Which enzyme is responsible for the breakdown of serotonin, norepinephrine,
and dopamine?
A. Acetylcholinesterase
B. Monoamine oxidase (MAO) ✅
C. Catechol-O-methyltransferase (COMT)
D. CYP3A4
Rationale: MAO breaks down monoamines; MAOIs inhibit this enzyme.
4. Which cytochrome P450 enzyme is most involved in the metabolism of many
psychotropic drugs?
A. CYP1A2
,B. CYP2D6 ✅
C. CYP2E1
D. CYP3A5
Rationale: CYP2D6 metabolizes many antidepressants, antipsychotics, and opioids;
genetic polymorphisms affect levels.
5. What is the primary mechanism of action of selective serotonin reuptake
inhibitors (SSRIs)?
A. Block dopamine D2 receptors
B. Inhibit serotonin reuptake ✅
C. Inhibit MAO
D. Block GABA receptors
Rationale: SSRIs block the serotonin transporter (SERT), increasing synaptic serotonin.
6. Which receptor is blocked by most typical antipsychotics?
A. 5-HT2A
B. D2 ✅
C. H1
D. M1
Rationale: D2 blockade in mesolimbic pathway reduces positive symptoms.
7. Which neurotransmitter is deficient in Alzheimer's disease and targeted by
donepezil?
A. Dopamine
B. Acetylcholine ✅
C. Serotonin
D. GABA
Rationale: Donepezil inhibits acetylcholinesterase, increasing acetylcholine.
8. What is the therapeutic index?
A. Ratio of toxic dose to therapeutic dose ✅
B. Time to peak effect
, C. Half-life of drug
D. Bioavailability
Rationale: Therapeutic index = TD50/ED50; narrow index requires monitoring.
9. Which phase of pharmacokinetics involves drug movement from site of
administration to bloodstream?
A. Absorption ✅
B. Distribution
C. Metabolism
D. Excretion
Rationale: Absorption is the first step.
10. Which factor most increases drug half-life?
A. Increased hepatic metabolism
B. Decreased renal clearance ✅
C. Increased protein binding
D. Increased first-pass effect
Rationale: Reduced clearance prolongs half-life.
11. Which is a prodrug requiring hepatic activation?
A. Fluoxetine
B. Venlafaxine
C. Buspirone
D. Valacyclovir ✅
Rationale: Valacyclovir is converted to acyclovir; among psychotropics,
lisdexamfetamine is a prodrug.
12. Which statement about steady-state concentration is correct?
A. Achieved after 1 half-life
B. Achieved after 4–5 half-lives ✅
C. Achieved immediately
