Which medication is considered a SNRI?

• A. Fluoxetine
• B. Desvenlafaxine
• C. Paroxetine
• D. Sertraline

Answer: (B)

Desvenlafaxine is recognized as a serotonin-norepinephrine reuptake inhibitor (SNRI). This class of medications works by inhibiting the reuptake of both serotonin and norepinephrine, two neurotransmitters that play significant roles in mood regulation. By increasing the levels of these neurotransmitters in the synaptic cleft, SNRIs can help alleviate symptoms of depression and anxiety. In contrast, the other medications listed—Fluoxetine, Paroxetine, and Sertraline—are classified as selective serotonin reuptake inhibitors (SSRIs). SSRIs primarily focus on enhancing serotonin levels by blocking its reuptake, and do not significantly impact norepinephrine reuptake. This distinctive mechanism differentiates SNRIs from SSRIs, helping healthcare providers choose appropriate treatments based on individual patient needs and conditions.
