Which of the following is NOT an SSRI?

Duloxetine is not classified as a selective serotonin reuptake inhibitor (SSRI). Instead, it is an antidepressant belonging to a different class known as serotonin-norepinephrine reuptake inhibitors (SNRIs). SNRIs work by increasing the levels of both serotonin and norepinephrine in the brain, which can help alleviate symptoms of depression and anxiety.

On the other hand, paroxetine, sertraline, and fluoxetine are all SSRIs. These medications specifically target the reuptake of serotonin, increasing its availability in the synaptic cleft, which can improve mood and emotional stability. Each of these SSRIs is commonly used to treat various anxiety disorders, depression, and other related conditions, demonstrating their effectiveness in managing mental health issues. Understanding the distinctions between these drug classes is essential for pharmacy technicians, as it impacts patient care and medication management.
