Which class of drugs includes medications used to treat depression and anxiety?

The class of drugs used to treat depression and anxiety includes SNRIs, or Serotonin-Norepinephrine Reuptake Inhibitors. These medications work by increasing the levels of serotonin and norepinephrine in the brain, neurotransmitters that are important for regulating mood and emotional responses. By enhancing the availability of these neurotransmitters, SNRIs can help alleviate the symptoms of both depression and anxiety, making them a commonly prescribed treatment option.

While SSRIs (Selective Serotonin Reuptake Inhibitors) also treat depression and anxiety by primarily targeting serotonin levels, SNRIs provide a broader effect by also affecting norepinephrine, which can be beneficial in certain types of depression and anxiety disorders. This makes SNRIs particularly useful for patients who may not respond adequately to SSRIs alone.

Beta-blockers and antihistamines do not typically have a direct role in treating depression or anxiety. Beta-blockers are primarily used for cardiovascular conditions and may be used off-label for performance anxiety, but they do not address the underlying mood disorders. Antihistamines are used to manage allergies and offer sedation but do not have a therapeutic effect on depression or anxiety.

In summary, SNRIs are the correct answer as this class
