How does sertraline function therapeutically?

• A. By inhibiting norepinephrine reuptake
• B. By blocking dopamine receptors
• C. By selectively inhibiting serotonin reuptake
• D. By increasing levels of glutamate

Answer: (C)

Sertraline is classified as a selective serotonin reuptake inhibitor (SSRI). Its therapeutic action is primarily achieved by selectively inhibiting the reuptake of serotonin in the presynaptic neuron. This mechanism increases the availability of serotonin in the synaptic cleft, effectively enhancing neurotransmission associated with mood regulation. The elevation of serotonin levels contributes to the alleviation of symptoms in conditions such as depression, anxiety disorders, and obsessive-compulsive disorder. This targeted inhibition of serotonin reuptake is what distinguishes sertraline from other classes of antidepressants. For example, some medications might affect norepinephrine or dopamine pathways, but sertraline specifically focuses on serotonin. By increasing serotonin availability, sertraline helps regulate various psychological and emotional processes, leading to improved mood and reduced anxiety.
