Which medication is classified as a selective serotonin reuptake inhibitor?

Fluvoxamine is classified as a selective serotonin reuptake inhibitor (SSRI), which is a common class of antidepressants. SSRIs work by inhibiting the reuptake of serotonin at the synaptic cleft, increasing the availability of serotonin in the brain. This mechanism is believed to enhance mood and alleviate symptoms of depression and anxiety.

Fluvoxamine, specifically, has been shown to be effective in treating various anxiety disorders as well as depression. Its selective action on serotonin makes it preferable in many cases due to a relatively favorable side effect profile compared to other classes of antidepressants. By effectively increasing serotonin levels, Fluvoxamine can help stabilize mood and decrease anxiety symptoms, making it a widely prescribed medication for these conditions.

Other medications listed do not fall under the category of SSRIs. For instance, mirtazapine is classified as a noradrenergic and specific serotonergic antidepressant (NaSSA), selegiline is a monoamine oxidase inhibitor (MAOI) used mainly in Parkinson's disease and major depressive disorder, and nefazodone is categorized as a serotonin antagonist and reuptake inhibitor (SARI). Each of these medications operates through different mechanisms and may have different indications and side effect
