Queen’s University researcher Ian Gilron has uncovered a more effective way of treating fibromyalgia, a medical condition characterized by chronic widespread pain typically accompanied by fatigue, as well as sleep, mood and memory problems.
The results of the trial suggest that combining pregabalin, an anti-seizure drug, with duloxetine, an antidepressant, can safely improve outcomes in fibromyalgia, including not only pain relief, but also physical function and overall quality of life. Until now, these drugs have been proven, individually, to treat fibromyalgia pain.
“Previous evidence supports added benefits with some drug combinations in fibromyalgia,” says, Dr. Gilron (Anesthesiology, Biomedical Sciences). “We are very excited to present the first evidence demonstrating superiority of a duloxetine-pregabalin combination over either drug alone.”
Fibromyalgia was initially thought to be a musculoskeletal disorder. Research now suggests it’s a disorder of the central nervous system – the brain and spinal cord. Researchers believe that fibromyalgia amplifies painful sensations by affecting the level and activity of brain chemicals responsible for processing pain signals.
“The condition affects about 1.5 to 5 per cent of Canadians – more than twice as many women as men. It can have a devastating on the lives of patients and their families,” explains Dr. Gilron. “Current treatments for fibromyalgia are either ineffective or intolerable for many patients.”
