A nurse is providing education to nurses in the psychiatric unit on antidepressant medications. To evaluate their learning, the educator asks one of the nurses, "How does fluoxetine (Prozac) achieve its effects?"
The nurse would be correct to state that fluoxetine (Prozac) achieves its effects by which of the following mechanisms of action?
a. Selectively inhibiting serotonin reuptake
b. Blocking the uptake of monoamines
c. Inhibiting monoamine oxidase-A in nerve terminals
d. Direct stimulation of serotonin receptors
ANS: A
Fluoxetine produces selective inhibition of serotonin reuptake and intensifies transmission at serotonergic synapses.
Fluoxetine does not act by blocking uptake of monoamines or inhibiting monoamine oxidase-A nerve terminals, nor does it directly stimulate serotonin receptors.
