Another noninjectable drug that probably is already being overused against MS has shown promise in an animal study, researchers at Pennsylvania State University reported at the WCTRIMS. It is naltrexone, developed for treatment of drug abuse.

"Thousands of people are taking this drug for MS on the basis of what other people have said," said Dr. Ian S. Zagon, distinguished university professor in neural and behavioral sciences at Penn State. "So, we decided to do animal studies about its efficacy."

The study of animals with an MS-like condition found that low-dose naltrexone helped, but high doses worsened the disease, Zagon said. Penn State is organizing a human trial of low-dose naltrexone in MS, he said. Meanwhile, use of the drug for the condition is not recommended, Zagon said.
