Treatment of restless legs syndrome: An evidence-based review and implications for clinical practice
Movement Disorders, 2008
Only in the last three decades, the restless legs syndrome (RLS) has been examined in randomized controlled trials. The Movement Disorder Society (MDS) commissioned a task force to perform an evidence-based review of the medical literature on treatment modalities used to manage patients with RLS. The task force performed a search of the published literature using electronic databases. The therapeutic efficacy of each drug was classified as being either efficacious, likely efficacious, investigational, nonefficacious, or lacking sufficient evidence to classify. Implications for clinical practice were generated based on the levels of evidence and particular features of each modality, such as adverse Produced by a task force commissioned by The Movement Disorder Society.
Update on the management of restless legs syndrome: existing and emerging treatment options
Nature and Science of Sleep, 2010
Restless legs syndrome (RLS) is a sensorimotor disorder, characterized by a circadian variation of symptoms involving an urge to move the limbs (usually the legs) as well as paresthesias. There is a primary (familial) and a secondary (acquired) form, which affects a wide variety of individuals, such as pregnant women, patients with end-stage renal disease, iron deficiency, rheumatic disease, and persons taking medications. The symptoms reflect a circadian fluctuation of dopamine in the substantia nigra. RLS patients have lower dopamine and iron levels in the substantia nigra and respond to both dopaminergic therapy and iron administration. Iron, as a cofactor of dopamine production and a regulator of the expression of dopamine type 2-receptor, has an important role in the RLS etiology. In the management of the disease, the first step is to investigate possible secondary causes and their treatment. Dopaminergic agents are considered as the first-line therapy for moderate to severe RLS. If dopaminergic drugs are contraindicated or not efficacious, or if symptoms are resistant and unremitting, gabapentin or other antiepileptic agents, benzodiazepines, or opioids can be used for RLS therapy. Undiagnosed, wrongly diagnosed, and untreated RLS is associated with a significant impairment of the quality of life.

Dopaminergic agents are the best-studied agents and are considered first-line treatment of restless legs syndrome (RLS). Extensive data are available for levodopa, pramipexole, and ropinirole, which have approval for the indication RLS, and to a smaller extent for cabergoline, pergolide, and rotigotine. Apart from one recent study, comparing two active drugs (levodopa and cabergoline), no comparative studies have been published. The individual treatment regimen with the most appropriate agent concerning efficacy and side effects has to be selected by the treating physician. On the basis of these clinical trials and expert opinion of the authors, a treatment algorithm is proposed to support the search for the optimal individual treatment. Opioids and anticonvulsants such as gabapentine are second-line options in individual patients. Iron substitution is justified in people with iron deficiency related RLS (ferritin concentration lower than 50 g/L).
Is restless legs syndrome underrecognized? Current management
Joint Bone Spine, 2006
Restless legs syndrome (RLS) is a poorly understood sensory-motor neurological disorder whose prevalence in Caucasian populations ranges from 10% to 15%. The patient reports unpleasant sensations in the lower limbs with dysesthesia resulting in an urge to move the legs. The symptoms occur during periods of inactivity, increasing in the evening and at night. Moving the legs provides relief. In 80% of cases, polysomnography shows periodic leg movements during sleep. Patients with idiopathic RLS often report similar symptoms in family members. Secondary RLS may be due to medications, diabetes mellitus, renal failure, iron deficiency, neurological disorders, or rheumatoid arthritis. In secondary RLS, the management rests on treatment of the cause. Symptomatic treatment is warranted in patients with moderateto-severe symptoms that adversely affect the quality of life. Dopaminergic agents are tried first. When they fail or induce adverse effects, weak opioids, benzodiazepines, anticonvulsants or, if needed, strong opioids, may be used.

Restless legs syndrome (RLS) (or Willis-Ekbom disease) is a neurological disorder with high prevalence among the endstage renal disease population. This is one of the most predominant types of secondary RLS, and it is called uremic RLS. Despite the fact that uremic RLS has been less studied compared to idiopathic RLS, recent studies now shed light in many aspects of the syndrome including clinical characteristics, impact, epidemiology, and treatment options. The current review discusses the above topics with special emphasis given on the management of uremic RLS, including the management of symptoms that often appear during a hemodialysis session. Uremic RLS symptoms may be ameliorated by using pharmacological and nonpharmacological treatments. Evidence so far shows that both approaches may be effective in terms of reducing the RLS symptom's severity; nevertheless, more research is needed on the efficiency of treatments for uremic RLS.
The pharmacological treatment for uremic restless legs syndrome: Evidence-based review
Movement Disorders, 2010
Restless legs syndrome (RLS) is a common and often misdiagnosed entity among the general population and it may be more common among dialysis patients, with an estimated prevalence of 6.6 to 21.5%. The treatment for uremic RLS has been controversial and therefore a systematic synthesis of the evidence is needed in order to evaluate the effectiveness and safety of treatments for uremic RLS. This was a systematic review of randomized or quasi-randomized doubleblind trials on treatments for uremic RLS. The outcomes considered were relief of RLS symptoms marked on a validated scale, subjective sleep quality, sleep quality measured using night polysomnography and actigraphy, quality of life measured subjectively, and adverse events associated with these treatments. Six eligible clinical trials were included. The results from subjective analyses in these studies were divergent, although objective analyses in one trial showed that there was a statistically significant improvement in periodic leg movement while asleep in the treatment group. No combined analysis (meta-analysis) was performed. The most common adverse event seen was gastrointestinal symptoms. Only a few therapeutic trials on patients with uremia with RLS have been published, and there is insufficient scientific evidence to favor any specific therapeutic regimen for uremic-associated RLS. Therapy using levodopa, dopaminergic agonists, anticonvulsants, and clonidine tend to be effective, but further studies are needed.

To make evidence-based recommendations regarding restless legs syndrome (RLS) management in adults. Articles were classified per the 2004 American Academy of Neurology evidence rating scheme. Recommendations were tied to evidence strength. In moderate to severe primary RLS, clinicians should consider prescribing medication to reduce RLS symptoms. Strong evidence supports pramipexole, rotigotine, cabergoline, and gabapentin enacarbil use (Level A); moderate evidence supports ropinirole, pregabalin, and IV ferric carboxymaltose use (Level B). Clinicians may consider prescribing levodopa (Level C). Few head-to-head comparisons exist to suggest agents preferentially. Cabergoline is rarely used (cardiac valvulopathy risks). Augmentation risks with dopaminergic agents should be considered. When treating periodic limb movements of sleep, clinicians should consider prescribing ropinirole (Level A) or pramipexole, rotigotine, cabergoline, or pregabalin (Level B).

Restless legs syndrome: diagnosis and review of management options
Neuropsychiatric Disease and Treatment, 2006
Restless legs syndrome (RLS) is one of the commonest movement disorders affecting sleep and also daytime functioning. The prevalence may be 8%-10% of the white Caucasian population. The diagnosis is simple and is based on a well-validated clinical questionnaire, yet misdiagnosis is common and the condition remains underdiagnosed and consequently inappropriately treated, often causing great distress to the sufferers. In spite of robust evidence for effective treatment of RLS, patients may often be told to "put up with the symptoms" and suffer the consequence of years of poor sleep which may lead to major lifestyle changes. This review addresses the diagnostic issues, the differential diagnosis, and the evidence base for treatment of the common condition.
