West Lafayette, Indiana - Researchers have discovered that a known neurotoxin may cause chronic pain in people who suffer from paralysis, and a drug that has been shown to remove the toxin might be used to treat the pain.
The toxin, called acrolein, is produced in the body after nerve cells are injured, triggering a cascade of biochemical events thought to worsen the injury's severity. The drug hydralazine, which has been approved by the U.S. Food and Drug Administration for hypertension, has been shown to be effective in reducing acrolein levels in the body.
New research shows hydralazine is effective in reducing chronic pain in laboratory animals and potentially in people who have suffered neurotrauma resulting in paralysis, said Riyi Shi (pronounced Ree Shee), a professor of neuroscience and biomedical engineering in Purdue's Department of Basic Medical Sciences, School of Veterinary Medicine, and Weldon School of Biomedical Engineering.
