Fibromyalgia (FM) is an illness that may involve medical, rheumatologic, autoimmune, sleep, endocrine and psychiatric pathology. It is a syndrome of recurrent pain at trigger points. Greater than 90% of these patients will report fatigue as a key symptom as well. There are several investigation lines into the treatment of FM induced pain. Exercise, behavioral therapy, amitryptiline, duloxetine, tramadol, sodium oxybate, pregabalin all have randomized trials and almost all focus on pain. There are very few studies evaluating cyclobenzaprine and none studying to Cyclobenzaprine ER formulation. None evaluate pain reduction, sleep and fatigue improvement.
