serotonin-norepinephrine reuptake inhibitors (SNRIs) are a class of drugs that treat depression and anxiety. They work by increasing the levels of serotonin and norepinephrine, two neurotransmitters that regulate mood, in the brain. SNRIs block the reabsorption of these chemicals by nerve cells, making them more available for communication between neurons. SNRIs can help improve symptoms such as low mood, lack of interest, nervousness, and worry.
