October 26, 20000 - For those that suffer from restless legs syndrome (RLS), there is news that cabergoline may be effective in reducing symptoms of RLS.

May 2, 2000 - Neurologists from Emory University have released data that demonstrates that a low dosage of the drug ropinirole is a safe and effective treatment for restless legs syndrome (RLS), a common but often undiagnosed neurologic disorder.

It has been known for over 30 years that anemia and low levels of iron in the blood are associated with symptoms of RLS. Chronic conditions such as diabetes, peripheral neuropathy (damage to the nerves in the hands and feet), alcoholism, Parkinson's disease, kidney failure, and rheumatoid arthritis may induce a longer-lasting RLS.

Ropinirole is a dopamine agonist that has been FDA-approved for use in the treatment of Parkinson's disease. It has not yet been approved for use in treating RLS.

This data was presented Monday, May 1 at the American Academy of Neurology's 52nd Annual Meeting in San Diego. (link no longer available)
