Which of the following medications are classified as SNRIs?

The classification of medications as SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) specifically includes Venlafaxine, Desvenlafaxine, and Duloxetine. These medications are designed to enhance the levels of neurotransmitters serotonin and norepinephrine in the brain, which are often implicated in the regulation of mood and anxiety.

Venlafaxine is particularly effective for major depressive disorder and generalized anxiety disorder. Desvenlafaxine is an active metabolite of venlafaxine and shares similar indications and mechanisms. Duloxetine is used for major depressive disorder and generalized anxiety disorder as well, and it is also effective for treating chronic pain.

The other options mention medications that belong to different classes, such as SSRIs (Selective Serotonin Reuptake Inhibitors) or are not classified strictly as SNRIs. For example, fluoxetine and sertraline, which are in the first option, are SSRIs, while citalopram is another SSRI that is listed in a different option. Understanding these distinctions is crucial for proper medication management in clinical practice.
