How would you describe the action of benzodiazepines to a patient?
a. Benzodiazepines raise the level of norepinephrine and serotonin in the brain by slowing the rate at which they are absorbed by the cells.
b. Benzodiazepines potentiate neurotransmitter activity of the central nervous system. They inhibit serotonin and norepinephrine reuptake and are a weak inhibitor of dopamine reuptake.
c. Benzodiazepines specifically block reabsorption of serotonin. They Inhibit neuronal reuptake of serotonin in the central nervous system (CNS), thus potentiating the activity of serotonin.
d. They work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain by opening GABA-activated chloride channels and allowing chloride ions to enter the neuron, making the neuron negatively charged and resistant to excitation.
