Subtopic 1: Anticonvulsant Drug Classes and
Mechanisms of Action (Q1–Q20)
1. Which of the following best describes the primary mechanism of action of
phenytoin in seizure control?
A. Enhances GABA-mediated chloride influx
B. Blocks voltage-gated sodium channels
C. Inhibits NMDA receptor activity
D. Stimulates serotonin release
Correct Answer: B. Blocks voltage-gated sodium channels
Rationale: Phenytoin primarily works by stabilizing neuronal membranes and
reducing repetitive firing by blocking voltage-gated sodium channels. This
helps prevent the spread of seizure activity.
2. Which anticonvulsant is classified as a GABA transaminase inhibitor,
increasing available GABA in the brain?
A. Carbamazepine
B. Vigabatrin
C. Ethosuximide
D. Lamotrigine
Correct Answer: B. Vigabatrin
Rationale: Vigabatrin irreversibly inhibits GABA transaminase, the enzyme
responsible for GABA degradation, thus increasing GABA levels and
enhancing inhibitory neurotransmission.
3. Which of the following anticonvulsants is most effective for absence
seizures due to its action on T-type calcium channels?
, 3
A. Valproic acid
B. Ethosuximide
C. Phenobarbital
D. Gabapentin
Correct Answer: B. Ethosuximide
Rationale: Ethosuximide specifically blocks T-type calcium channels in
thalamic neurons, making it highly effective for treating absence seizures.
4. What is the mechanism by which benzodiazepines like diazepam help
control seizures?
A. Inhibiting sodium influx
B. Blocking glutamate receptors
C. Enhancing GABA-A receptor activity
D. Inhibiting GABA metabolism
Correct Answer: C. Enhancing GABA-A receptor activity
Rationale: Benzodiazepines enhance the affinity of GABA for the GABA-A
receptor, increasing chloride influx and producing a calming, anticonvulsant
effect.
5. Which anticonvulsant is known to block sodium channels and also inhibits
high-frequency neuronal firing through calcium channel effects?
A. Topiramate
B. Lamotrigine
C. Levetiracetam
D. Zonisamide
, 4
Correct Answer: B. Lamotrigine
Rationale: Lamotrigine inhibits voltage-sensitive sodium channels and may
also impact calcium channels, reducing excitatory neurotransmitter release.
6. Which antiepileptic drug works by binding to synaptic vesicle protein 2A
(SV2A) and modulating neurotransmitter release?
A. Gabapentin
B. Phenobarbital
C. Levetiracetam
D. Oxcarbazepine
Correct Answer: C. Levetiracetam
Rationale: Levetiracetam acts on SV2A, a protein involved in synaptic vesicle
function, which modulates neurotransmitter release and seizure activity.
7. What is the mechanism of action of valproic acid that makes it a broad-
spectrum anticonvulsant?
A. NMDA receptor blockade
B. Multiple: increases GABA, blocks sodium and calcium channels
C. Enhances serotonin transmission
D. Selective sodium channel inhibition
Correct Answer: B. Multiple: increases GABA, blocks sodium and calcium
channels
Rationale: Valproic acid has a multifaceted mechanism: increasing GABA
levels, blocking voltage-gated sodium channels, and inhibiting T-type calcium
channels, making it effective for various seizure types.
