Duloxicaine is part of the 
Local Anesthetic / SNRI Kits class and treats 
Fibromyalgia, 
Depression, 
Anxiety and other conditions. Local anesthetic/
SNRI kits are co-packaged products used to treat diabetic peripheral neuropathic 
pain, fibromyalgia, and other 
musculoskeletal pain. SNRI changes perception of pain by increasing levels of serotonin and norepinephrine in the brain. Local anesthetic works by  blocking nerve impulses to reduce pain. Duloxicaine is only available as a brand name drug.
