QUESTION: What are benzodiazepines? - ✔✔CORRECT ANS: A class of drugs used for anxiety
and other purposes.
QUESTION: What are the uses of benzodiazepines? - ✔✔CORRECT ANS: Sedation, hypnosis,
muscle relaxation, anxiolysis, anticonvulsant, amnesia, insomnia, alcohol withdrawal.
QUESTION: What is the structure of benzodiazepines? - ✔✔CORRECT ANS: Benzodiazepine ring
with 2 nitrogen atoms at positions 1 & 4, phenyl group at position 5, and an electronegative
group at position 7.
QUESTION: How do benzodiazepines work? - ✔✔CORRECT ANS: They promote the binding of
GABA to the GABAA receptor, enhancing GABA-induced chloride currents and inhibiting
neuronal cell excitation.
QUESTION: How are benzodiazepines metabolized? - ✔✔CORRECT ANS: They are oxidized in
the liver via CYP enzymes, primarily CYP3A4.
QUESTION: What are the active metabolites of benzodiazepines? - ✔✔CORRECT ANS:
Diazepam (with a half-life exceeding 100 hours) and midazolam (rapidly metabolized to an α-
hydroxylated compound with biologic activity).
QUESTION: Which benzodiazepines have no active metabolites? - ✔✔CORRECT ANS:
Oxazepam, lorazepam, and temazepam.
QUESTION: What factors can alter the metabolism of benzodiazepines? - ✔✔CORRECT ANS:
Disease and age.
1
,QUESTION: What is the duration of action of benzodiazepines primarily determined by? -
✔✔CORRECT ANS: The α phase (distribution-redistribution from CNS) dynamics rather than the
rate of elimination.
QUESTION: What are the pharmacodynamic effects of benzodiazepines on the CNS? -
✔✔CORRECT ANS: CNS depressant effects including anxiolysis, sedation, sleep, anticonvulsant,
amnesia, muscle relaxation, and inhibition of alcohol withdrawal symptoms.
QUESTION: What effect do high doses of benzodiazepines have on CMR02 & CBF? -
✔✔CORRECT ANS: They reduce CMR02 & CBF.
QUESTION: What effect do benzodiazepines have on the threshold to local anesthetic-induced
seizures? - ✔✔CORRECT ANS: They increase the threshold to local anesthetic-induced seizures.
QUESTION: What is the dose-related effect of benzodiazepines on anterograde amnesia? -
✔✔CORRECT ANS: They cause anterograde amnesia at high doses.
QUESTION: What are the potential drawbacks of benzodiazepine use? - ✔✔CORRECT ANS:
Awareness regarding addiction, withdrawal, recreational abuse, and the development of other
drug classes has led to a decline in their use.
QUESTION: Which CYP enzyme is primarily responsible for the metabolism of benzodiazepines?
- ✔✔CORRECT ANS: CYP3A4.
QUESTION: Which benzodiazepine has a half-life exceeding 100 hours? - ✔✔CORRECT ANS:
Diazepam.
QUESTION: Which benzodiazepine is rapidly metabolized to an α-hydroxylated compound with
biologic activity? - ✔✔CORRECT ANS: Midazolam.

QUESTION: What is the dose-related effect of benzodiazepines on anterograde amnesia? -
✔✔CORRECT ANS: They cause anterograde amnesia at high doses.
QUESTION: What does midazolam achieve at low doses? - ✔✔CORRECT ANS: Rapid onset,
short duration of action, and half-life
QUESTION: How long does the effect of midazolam usually last? - ✔✔CORRECT ANS: 20-30
minutes
QUESTION: Does midazolam produce reliable retrograde amnesia? - ✔✔CORRECT ANS: No
