Serotonin and Norepinephrine Reuptake Inhibitors are used to treat depression.
Serotonin norepinephrine reuptake inhibitors (SNRIs) inhibit the reuptake of serotonin and norepinephrine at the level of the synapse. This class of antidepressant drugs are used to treat depression, anxiety, obsessive-compulsive disorder (OCD), neuropathic pain, and other conditions.
SNRIs increase the levels of the mood related neurotransmitters serotonin and norepinephrine. In contrast, the more widely used SSRI antidepressants only increase serotonin levels.
