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. In contrast, new evidence supporting three alpha-2-delta ligand calcium channel blockers — gabapentin enacarbil, gabapentin, and pregabalin — led the task force to support them as strong recommendations for RLS treatment. 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. We define refractory RLS and describe management approaches, including combination therapy and the use of high-potency opioids. Treatment of RLS in pregnancy and childhood is discussed. Iron status should be assessed in all patients with restless legs syndrome (RLS) and appropriate oral or intravenous iron therapy considered. Gabapentin has been shown to improve RLS in a small number of clinical studies, but is limited by its short half-life and variable bioavailability. Gabapentin enacarbil is a novel prodrug of gabapentin designed to overcome these pharmacokinetic limitations. Gabapentin. GBP is structurally analogous to the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) ().It is an effective anticonvulsant and analgesic however only minimally ameliorates RLS due to several pharmacokinetic limitations. Keywords: restless legs syndrome, RLS, gabapentin enacarbil, Horizant, dopamine agonists. Introduction. Restless legs syndrome (RLS) is a common neurological disorder among adult patients that often disrupts sleep and can impact activities of daily living. Opioids should be considered for RLS patients, especially for those who have failed other therapies since they are very effective for severe cases. When monitored appropriately, they can be very safe and durable for long term therapy. Restless legs syndrome and cardiovascular disease: a research roadmap. Sleep Med. 2017;31:10–17.

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 How Gabapentin Works for Restless Legs Syndrome. Gabapentin’s mechanism of action involves binding to specific calcium channels in the nervous system. By doing so, it decreases the release of excitatory neurotransmitters such as glutamate. In moderate to severe primary restless legs syndrome (RLS), clinicians should consider prescribing a pharmacologic agent to reduce RLS symptoms: Strong Evidence Pramipexole, rotigotine, cabergoline*, and gabapentin enacarbil (Level A). 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 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. Abstract. Gabapentin enacarbil is a prodrug of the anticonvulsant gabapentin. The efficacy and safety of gabapentin enacarbil for the treatment of moderate to severe primary restless legs syndrome (RLS) has been evaluated in several clinical trials in the United States and Japan. Gabapentin (Neurontin).Gabapentin was effective in treating RLS in limited studies. 29, 30 In a crossover study (22 patients), individuals receiving gabapentin experienced improvement in 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. Restless legs syndrome (RLS) is a sensory-motor neurologic disorder present to a clinically significant degree in 2% to 3% of the adult population, more commonly with advancing age and in women, that dramatically affects sleep and quality of life. Addressing factors that worsen RLS (eg, iron deficiency, antidepressant or antihistamine administration, OSA) is an important first step in 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.
