A drug used in over-the-counter cough medicine may treat symptoms of multiple sclerosis -- offering inexpensive therapy for a disease with few treatment options, according to UC Davis researchers.

In tests using mice, the drug, dextromethorphan, was found to significantly reduce the loss of myelin, the fatty sheath surrounding nerve fibers in the central nervous system. It also minimized the development of paralysis during MS attacks.

The finding provides an opportunity to pursue a new treatment strategy"with a drug that is widely available, inexpensive and known to be safe," said Wenbin Deng, principal investigator of the study and a UC Davis assistant professor.
