FDA-approved drug pregabalin effectively treats RLS symptoms with less side effects

In continuation of my update on pregabalin

A report in the Feb. 13 New England Journal of Medicine confirms previous studies suggesting that long-term treatment with the type of drugs commonly prescribed to treat restless leg syndrome (RLS) can cause a serious worsening of the condition in some patients. The year-long study from a multi-institutional research team found that pregabalin - which is FDA-approved to treat nerve pain, seizures, and other conditions - was effective in reducing RLS symptoms and was much less likely to cause symptom worsening than pramipexole, one of several drugs that activate the dopamine neurotransmission system and are FDA approved for treatment of RLS.

"Our key finding is that dopaminergic drugs, while very effective for many people with RLS, can worsen symptoms in some patients over time, while non-dopaminergic pregabalin is not associated with this disturbing side effect," says John Winkelman, MD, PhD, of the Massachusetts General Hospital Department of Psychiatry, senior author of the study. "Those treating RLS patients with dopaminergic drugs need to be aware of this common complication and exercise caution if their symptoms worsen."
