Which neurotransmitter is primarily impacted by the antidepressant Prozac?

Prozac, known generically as fluoxetine, primarily impacts serotonin, which is a neurotransmitter associated with mood regulation. This antidepressant works by inhibiting the reuptake of serotonin in the brain, leading to increased availability of serotonin in the synaptic cleft. This mechanism is instrumental in alleviating symptoms of depression and anxiety, as serotonin plays a crucial role in mood stabilization and emotional well-being. As a result, the correct choice emphasizes the drug's direct influence on serotonin levels, thereby reinforcing its significance in the treatment of depression and related disorders.
