Treatment of idiopathic restless legs syndrome (RLS) with gabapentin

Nine patients with idiopathic restless legs syndrome (RLS) were treated with 300 mg of gabapentin as an initial dose and an up-titration until relief of symptoms for 4 weeks. Subjective symptoms improved significantly. Polysomnographic data showed a reduction of periodic leg movements during sleep (PLMS) (p = 0.003) and PLMS index (p = 0.001). The authors conclude that gabapentin provides a well-tolerated and effective treatment of idiopathic RLS.
