Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) are a class of medications used primarily to treat depression and anxiety. They work by increasing the levels of two important chemicals in the brain—serotonin and norepinephrine—that help regulate mood, energy, and stress. By blocking the reabsorption of these chemicals into nerve cells, SNRIs enhance their activity, which can improve symptoms of depression and anxiety. They are generally effective and well-tolerated but may have side effects like nausea or fatigue. SNRIs are often prescribed when other treatments, such as simpler antidepressants, haven't been fully effective.
