Which class of medication does Fluoxetine belong to?

Fluoxetine is classified as a selective serotonin reuptake inhibitor (SSRI) antidepressant. This class of medications works by specifically inhibiting the reuptake of serotonin in the brain, leading to an increase in serotonin levels in the synaptic cleft. The elevated serotonin levels are thought to contribute to the alleviation of depressive symptoms, as serotonin plays a crucial role in mood regulation.

SSRIs like Fluoxetine are commonly prescribed due to their favorable side effect profiles compared to older antidepressants. They tend to have lower instances of sedation, anticholinergic effects, and cardiovascular side effects, making them safer options for many patients. This is in contrast to other classes of antidepressants mentioned, such as MAOI (monoamine oxidase inhibitors), SNRIs (serotonin-norepinephrine reuptake inhibitors), and TCAs (tricyclic antidepressants), which work through different mechanisms and may have a broader range of side effects.

The specific action of SSRIs on serotonin makes Fluoxetine particularly effective for conditions like major depressive disorder and anxiety disorders, helping to stabilize mood and improve overall emotional well-being.
