Heart-Valve Disease Linked To Two Parkinson's Drugs
The risk of heart valve damage with two drugs for Parkinson's disease may be far greater than was known, new research suggests. The drugs are not the main treatment for Parkinson's, but one is also sometimes used to treat restless legs syndrome. A study by Italian researchers found that roughly one-fourth of Parkinson's patients taking pergolide or cabergoline, sold as Permax, Dostinex and other brands, had moderate to severe heart valve problems. Another study, by German doctors, found that users of either drug were five to seven times more likely to have leaky heart valves than those on other types of Parkinson's medications. Both studies were reported in Thursday's New England Journal of Medicine
