Gabapentin enacarbil is a novel prodrug of gabapentin designed to overcome these pharmacokinetic limitations. In vitro and in vivo studies have demonstrated that gabapentin enacarbil has improved absorption, bioavailability and pharmacokinetics compared with gabapentin. 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. After a 1-week washout they crossed over to the alternative treatment In patients with secondary RLS associated with end-stage renal disease/hemodialysis (ESRD/HD): Moderate Evidence Vitamin C and E supplementation (alone or in combination) (Level B). Weak Evidence Ropinirole, levodopa, or exercise (Level C). Insufficient Evidence Gabapentin or IV iron dextran in RLS associated with ESRD/HD (Level U).

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. Learn how gabapentin, a medication for seizures and nerve pain, can also help with restless legs syndrome. Find out the dosage, effectiveness, side effects, and precautions of gabapentin for RLS. 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). Learn about the symptoms, causes and treatments of restless legs syndrome (RLS), a condition that causes uncomfortable sensations in the legs and an urge to move them. Find out how gabapentin and other medicines may help with RLS symptoms. This article reviews the management of restless legs syndrome (RLS), a common disorder with symptoms of leg discomfort and movement. It discusses nonpharmacologic and pharmacologic approaches, including alpha 2 -delta ligands, dopamine agonists, opioids, and iron therapy. Gabapentin enacarbil has theoretical pharmacokinetic advantages over gabapentin, and as such, could also be considered if a patient fails gabapentin RLS therapy. The dose of gabapentin for the treatment of RLS is 300–1800 mg daily, typically administered in two to three doses throughout the day. 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 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. Keywords: Restless legs syndrome, Dopamine agonists, Ropinirole, Pramipexole, Rotigotine, Gabapentin enacarbil, Opioids, Methadone, Augmentation, Anticonvulsants Introduction Restless legs syndrome (RLS) is a neurological sensorimotor disorder that is diagnosed based on 4 essential clinical criteria that were established by the International Gabapentin Gabapentin may help relieve RLS symptoms and is used when RLS is accompanied by pain. Pregabalin Pregabalin , a nondopaminergic alpha-2-delta ligand, may also be useful for RLS accompanied by pain although use of this medication to treat RLS has not been extensively studied. 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. The American Academy of Sleep Medicine recommends gabapentin, gabapentin enacarbil, and pregabalin as strong options for restless legs syndrome (RLS) treatment. These medications are not associated with the augmentation of RLS symptoms observed with dopamine agonists. Gabapentin enacarbil is a prescription medicine used to treat moderate-to-severe primary restless legs syndrome (RLS). It is also used to manage postherpetic neuralgia, a condition caused by shingles. Learn about its side effects, precautions, and interactions. 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.
