That makes Cymbalta the first antidepressant approved to treat fibromyalgia, which is a chronic disorder of the muscles and related soft tissue, including ligaments and tendons. Its main symptoms are muscle pain, fatigue, sleep disturbances, and tender points at certain points of the body.
Cymbalta belongs to a class of drugs called serotonin and norepinephrine reuptake inhibitors (SNRIs).
For three months, the patients either took Cymbalta or a placebo. Cymbalta trumped the placebo at pain reduction and overall improvement.
Cymbalta is the second drug approved by the FDA to treat fibromyalgia. Nearly a year ago, the FDA approved Lyrica as the first drug treatment for fibromyalgia. Lyrica also treats nerve pain caused by shingles and diabetes, as well as reducing some forms of epileptic seizures.
