Compare Gabapentin vs Gabapentin Enacarbil head-to-head with other drugs for uses, ratings, cost, side effects and interactions. To synthesize evidence from available randomized controlled trials (RCT) to compare the efficacies of dopaminergic drugs (pramipexole, ropinirole and rotigotine) and α-2-δ ligands (gabapentin enacarbil and pregabalin) for the treatment of restless legs syndrome (RLS). We searched PubMed for all elig Lee DO, Ziman RB, Perkins AT, et al; XP053 Study Group. A randomized, double-blind, placebo-controlled study to assess the efficacy and tolerability of gabapentin enacarbil in subjects with restless legs syndrome. J Clin Sleep Med. 2011;7(3):282-292. Walters AS, LeBrocq C, Dhar A, et al; International Restless Legs Syndrome Study Group. In double-blind, multicentre trials, treatment with gabapentin enacarbil 600 mg/day for 12 weeks significantly improved the symptoms of moderate to severe primary RLS in adults. Gabapentin enacarbil also significantly improved RLS pain scores and generally improved sleep and mood outcomes. Horizant is a brand-name-only tablet that contains gabapentin enacarbil, a prodrug of gabapentin. Prodrugs like gabapentin enacarbil turn into the active form of the medication once they enter the body. Horizant is FDA-approved to treat nerve pain from shingles (postherpetic neuralgia) and restless leg syndrome (RLS) in adults. What is Gralise? 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. Horizant ® is absorbed differently from regular gabapentin. This means it provides extended release, working day and night to treat Restless Legs Syndrome (RLS) and Postherpetic Neuralgia (PHN). Learn more about how Horizant ® works differently in the body from other prescription medications in the same drug class. More about Horizant (gabapentin enacarbil) Ratings & Reviews Gabapentin has an average rating of 7.2 out of 10 from a total of 2568 ratings on Drugs.com. 64% of reviewers reported a positive effect, while 21% reported a negative effect. In vitro and in vivo studies have demonstrated that gabapentin enacarbil has improved absorption, bioavailability and pharmacokinetics compared with gabapentin. Phase II and III studies have demonstrated that gabapentin enacarbil is generally well tolerated and is useful in the treatment of RLS. There are three gabapentinoids on the market: gabapentin, gabapentin enacarbil, and pregabalin. These drugs are considered first-line therapy for RLS. Gabapentin enacarbil and pregabalin tend to be absorbed better and more reliably effective than gabapentin due to variability in how gabapentin is absorbed in the intestines. Published concerns about dopaminergic augmentation of RLS symptoms from levodopa date back to the mid-1990s. 29 Heightened awareness of augmentation with long-term dopamine agonist use emerged in the early 2000s as their clinical use became widespread. 29 – 33 Furthermore, the occurrence of impulse control disorders in patients with RLS Compare the effectiveness of gabapentin vs. gabapentin enacarbil for restless legs syndrome based on the experiences of 2,275 members of the restless legs syndrome research community. Placebo-controlled trials of gabapentin enacarbil demonstrate considerable efficacy in the treatment of RLS. However, head-to-head trials comparing gabapentin enacarbil with other medications used in the treatment of RLS, including gabapentin, are lacking. Results and recommendations: In moderate to severe primary RLS, clinicians should consider pre-scribing medication to reduce RLS symptoms. Strong evidence supports pramipexole, rotigotine, cabergoline, and gabapentin enacarbil use (Level A); moderate evidence supports ropinirole, pre-gabalin, and IV ferric carboxymaltose use (Level B). Technically it’s gabapentin enacarbil, and the “enacarbil” refers to a molecule added to the drug which allows it to be absorbed along the entire GI tract, resulting in greater blood levels for a longer period of time. The recommended dosage for RLS is Horizant 600mg once daily at about 5pm. The effectiveness of gabapentin enacarbil in the treatment of moderate-to-severe primary RLS was demonstrated in two 12-week randomized, placebo-controlled clinical studies in adults diagnosed with RLS using the International Restless Legs Syndrome Study Group diagnostic criteria. 3 4 Statistically significant differences (P<0.05) between the In terms of efficacy, both Gabapentin enacarbil and Gabapentin have been shown to be effective in treating RLS and neuropathic pain. However, some studies suggest that Gabapentin enacarbil may have a more rapid onset of action and longer duration of effect compared to Gabapentin. 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 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. 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.
