what is the primary mechanism of action of benzodiazepines?

• serotonin reuptake inhibition
• norepinephrine reuptake inhibition
• gaba receptor agonism
• dopamine receptor antagonism

Explanation:

Benzodiazepines act by enhancing the effects of GABA (gamma - aminobutyric acid), a major inhibitory neurotransmitter in the brain. They are agonists at the GABA receptor, which increases the inhibitory neurotransmission. Serotonin reuptake inhibition is the mechanism of SSRIs (selective serotonin reuptake inhibitors), norepinephrine reuptake inhibition is for drugs like SNRIs (serotonin - norepinephrine reuptake inhibitors), and dopamine receptor antagonism is the mechanism of antipsychotics like typical antipsychotics. So the correct mechanism for benzodiazepines is GABA receptor agonism.

Answer:

C. GABA receptor agonism
