Key takeaways Although gabapentin is traditionally prescribed for seizure management and postherpetic neuralgia, it is also used off-label for restless legs syndrome (RLS) and many other nerve conditions. Gabapentin enacarbil is one of four medications approved by the U.S. Food and Drug Administration (FDA) for the treatment of RLS. Gabapentin helps improve the nerve signals to the muscles of Horizant (gabapentin enacarbil) is the version approved for the treatment of RLS, while Neurontin (gabapentin) is the version sometimes used off-label to relieve RLS symptoms. 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. 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. Absorption of Abstract Objective: To assess the effects of gabapentin on sensory and motor symptoms in patients with restless legs syndrome (RLS). Gabapentin and pregabalin may be preferred in restricted patient groups, including patients with severe sleep disturbance (disproportionate to other RLS symptoms), co-morbid insomnia or anxiety, RLS related or co-morbid pain, or with a history of ICD. 3 However, in the first instance it is recommended that these co-morbidities are investigated 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 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. Other agents including benzodiazepines, narcotics, and anticonvulsants have been used to treat RLS. Gabapentin has been shown Description 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. Gabapentin enacarbil is also used to manage a condition called postherpetic neuralgia, which is pain that occurs after Gabapentin offers a promising treatment option for individuals suffering from restless legs syndrome, particularly for those who have not found sufficient relief with other medications. Its ability to modulate nerve signaling, alleviate discomfort, improve sleep quality, and reduce pain makes it a valuable tool in the management of RLS symptoms. 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 Gabapentin can help alleviate the uncomfortable sensations and urge to move the legs that are characteristic of RLS. How Gabapentin Works for RLS Gabapentin is an anticonvulsant and neuropathic pain medication. It’s thought to work by modulating neurotransmitters in the brain, especially those related to pain signaling and nerve activity. Q. What can you tell me about gabapentin for restless legs syndrome? I find it very helpful. Are there side effects I should watch for? 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). Medicines such as gabapentin, gabapentin enacarbil and pregabalin are the first line of treatment for most people with RLS. These medicines can cause side effects such as dizziness, unsteadiness, mental fog and weight gain. Medicines that increase dopamine in the brain. These medicines affect levels of the chemical messenger dopamine in the brain. Practice Guideline: Treatment of Restless Legs Syndrome in Adults This is a summary of the American Academy of Neurology (AAN) guideline, “Treatment of restless legs syndrome in adults,” which was published in Neurology® online on November 16, 2016, and appears in the December 13, 2016, print issue. Treatment of Restless Legs Syndrome in Adults This information sheet is provided to help you understand the evidence for treating restless legs syndrome (RLS). It is a service of the American Academy of Neurology (AAN). 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, 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. It’s initiated at a low dose and increased gradually. Continuity in usage is crucial, as full effects may take up to four weeks 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. These medications are not associated with the augmentation of RLS symptoms observed with the dopaminergic agents. HORIZANT® (gabapentin enacarbil) Extended-Release Tablets are indicated for the treatment of moderate-to-severe primary Restless Legs Syndrome (RLS) in adults. HORIZANT is not recommended for patients who are required to sleep during the daytime and remain awake at night. Restless legs syndrome is a common neurologic movement disorder that affects approximately 10 percent of adults. Of those affected with this condition, approximately one third have symptoms severe
