Serotonin-norepinephrine reuptake inhibitors

Serotonin-norepinephrine reuptake inhibitors (SNRIs) are a class of medications primarily used to treat depression and anxiety. They work by increasing the levels of two key brain chemicals, serotonin and norepinephrine, which help regulate mood, energy, and emotional balance. SNRIs block the reabsorption (reuptake) of these chemicals into nerve cells, allowing more of them to remain active in the brain. This enhanced signaling can improve symptoms of depression and anxiety over time. Common SNRIs include medications like venlafaxine and duloxetine, and they are generally used under medical supervision due to potential side effects.
