What class of drugs does Duloxetine belong to?

SSRIs
SNRIs
TCAs
MAOIs

The correct answer is: SNRIs

Duloxetine belongs to the class of drugs known as SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors). SNRIs work by increasing the levels of serotonin and norepinephrine in the brain, which can help improve mood and relieve symptoms of depression and anxiety. A. SSRIs (Selective Serotonin Reuptake Inhibitors) primarily work by increasing the levels of serotonin in the brain and are commonly prescribed for depression and anxiety disorders. C. TCAs (Tricyclic Antidepressants) are an older class of antidepressants that work by increasing the levels of serotonin and norepinephrine in the brain, but they tend to have more side effects compared to newer classes of antidepressants like SNRIs. D. MAOIs (Monoamine Oxidase Inhibitors) are another class of antidepressants that work by blocking the enzyme monoamine oxidase, leading to increased levels of neurotransmitters such as serotonin, norepinephrine, and dopamine. MAOIs are used less frequently today due to their potential for serious drug interactions and side effects.
