Restless legs syndrome (RLS) is a neurologic movement disorder that affects approximately 10 percent of adults. 1 – 3 About one third of those with RLS have symptoms of moderate to severe The FDA approved gabapentin enacarbil in 2011 as the first non-dopaminergic agent for the treatment of restless legs syndrome (RLS) symptoms. Although gabapentin enacarbil is a pro-drug of gabapentin, its pharmacokinetics differ. To request a copy of the clinical practice guideline, “Treatment of restless legs syndrome and periodic limb movement disorder,” or the systematic review, meta-analysis, and GRADE assessment, or to arrange an interview with Dr. Winkelman or an AASM spokesperson, please contact the AASM at media@aasm.org. Accepted papers, which are published This article explains what gabapentin is, its approved and off-label uses, and how the drug works to treat restless legs syndrome and other medical conditions. It also describes the possible side effects and risks and lists other drugs and treatments that may help ease RLS symptoms. Gabapentin enacarbil is used to treat moderate-to-severe primary Restless Legs Syndrome (RLS). RLS is a neurologic disorder that makes the legs feel uncomfortable. This results in an irresistible feeling of wanting to move your legs to make them comfortable. Objective: To assess the effects of gabapentin on sensory and motor symptoms in patients with restless legs syndrome (RLS). Methods: Patients with RLS (22 idiopathic, 2 secondary to iron deficiency) were randomized and treated for 6 weeks with either gabapentin or placebo. e2 Allen RP, Walters AS, Montplaisir J, et al.

Gabapentin enacarbil available under the trade name Horizant is the only gabapentin product approved for treatment of Restless Legs Syndrome (RLS). A daily dose of 1200 mg provided no additional benefit compared with the 600 mg dose, but caused an increase in adverse reactions. Restless legs syndrome (RLS) is a common sleep-related neurological disorder that is characterized by the urge to move, worsening at rest, improvement with activity, and worsening in the evening and night. Dopamine agonists are usually the first-line therapy. Restless legs syndrome and cardiovascular disease: a research roadmap. Sleep Med. 2017;31:10–17. Crossref Google Scholar; 66.

Sleep Med Rev. 2023;69:101770. The use of gabapentin for restless legs syndrome (RLS) is off-label. Initial dose of 300 mg if the person is under 65 years old and 100 mg if the person is over 65 years old. Maximum recommended dose for RLS is 2700 mg. CKS did not identify any specific guidance on dose titration for use in RLS. Gabapentin enacarbil (marketed as Horizant) carries an FDA indication for the treatment of restless legs syndrome at a dose of 600 mg in the early evening, although FDA-approved doses of 1200 mg are permitted for other indications and used in some of the RLS clinical trials. Objective: To assess the effects of gabapentin on sensory and motor symptoms in patients with restless legs syndrome (RLS). Methods: Patients with RLS (22 idiopathic, 2 secondary to iron deficiency) were randomized and treated for 6 weeks with either gabapentin or placebo. Gabapentin, primarily used for seizures and nerve pain, is also employed for Restless Legs Syndrome (RLS). It affects nerve signalling rather than muscles. Gabapentin’s effectiveness for RLS may take weeks, with dosage ranging from 300 mg to 3,600 mg daily. Keywords: restless legs syndrome, pharmacotherapy, gabapentin, gabapentin enacarbil Introduction Restless Legs Syndrome (RLS) is a prevalent, disabling sleep-associated movement disorder requiring long-term drug therapy. Restless legs syndrome (RLS) is a common disorder. The population prevalence is 1.5% to 2.7% in a subgroup of patients having more severe RLS with symptoms occurring 2 or more times a week and causing at least moderate distress. It is important for primary care physicians to be familiar with the disorder and its management. Much has changed in the management of RLS since our previous revised Restless legs syndrome (RLS) refers to an urge to move the legs, usually associated with unpleasant sensations. The urge to move the legs is worse at rest and at night and is relieved by movement. RLS is commonly associated with sleep disturbance and with involuntary, jerking movements of the legs during sleep, known as periodic limb movements A. Gabapentin enacarbil (Horizant) has been approved by the FDA for the treatment of restless legs syndrome (RLS) and postherpetic neuralgia (the pain that can linger after a bout of shingles). It is different from plain gabapentin (Neurontin or Gralise).
