Horizant vs Gabapentin – Which Is Better For RLS? Due to the improved bioavailability and pharmacokinetics, Horizant is more effective for reducing the symptoms of restless legs syndrome than Gabapentin. 5.3 Lack of Interchangeability With Gabapentin HORIZANT is not interchangeable with other gabapentin products because of differing pharmacokinetic profiles. The same dose of HORIZANT results in different plasma concentrations of gabapentin relative to other gabapentin products [see Clinical Pharmacology (12.3)]. A total of 270 drugs are known to interact with Gabapentin: 28 major drug interactions (148 brand and generic names) 232 moderate drug interactions (1026 brand and generic names) Neurontin: Gabapentin · Oral capsule: 100 mg, 300 mg, 400 mg · Oral tablet: 600 mg, 800 mg · Oral solution: 50 milligrams per milliliter (mg/mL) Gralise: Gabapentin · Oral tablet: 300 mg, 600 mg: Horizant: Gabapentin enacarbil · ER tablet: 300 mg, 600 mg: Lyrica: Pregabalin The same dose of HORIZANT results in different plasma concentrations of gabapentin relative to other gabapentin products. The safety and effectiveness of HORIZANT in patients with epilepsy have not been studied. HORIZANT is not the same medicine as gabapentin [for example, NEURONTIN ® (gabapentin) and GRALISE ® (gabapentin)]. HORIZANT should not be used in their place.

CSA Schedule 1 View glossary of CSA terms 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).

HORIZANT is not the same medicine as gabapentin [for example, NEURONTIN ® (gabapentin) and GRALISE ® (gabapentin)]. HORIZANT should not be used in their place. Do not take these or other gabapentin products while taking HORIZANT. are pregnant or plan to become pregnant. It is not known if HORIZANT will harm your unborn baby. Patients (N=12) were randomized to 3 different treatment sequences, each receiving 3 doses: a 626 mg gabapentin-equivalent dose of Horizant® with food, a 626 mg gabapentin-equivalent dose of Horizant® without food, and a 600 mg dose of conventional gabapentin without food. Patients had a 7-day washout period between doses. Gabapentin is not the same as pregabalin, even though they both belong to the same class of medicine, called gabapentinoids, and work similarly. Lyrica and Lyrica CR are the only brands of pregabalin. Neurontin is a brand name for gabapentin. Other brands of gabapentin include Gralise and Horizant. Horizant is a brand-name version of gabapentin, which is also known as Neurontin, and is used to treat patients with moderate to severe Restless Leg Syndrome, RLS and postherpetic neuralgia. The main advantage of Horizant is that it is a “pro-drug”of gabapentin. Compare Gabapentin vs Horizant head-to-head with other drugs for uses, ratings, cost, side effects and interactions. Horizant contains gabapentin enacarbil, a prodrug of gabapentin. Each 600 mg tablet of Horizant, once metabolized, is equivalent to about 600 mg of gabapentin. This formulation allows for an extended-release, providing a controlled conversion to gabapentin in the body. Horizant is a prescription medication that combines gabapentin with an extended-release formulation of gabapentin, making it a convenient option for those who need to manage RLS and anxiety. However, Horizant can cause a range of side effects, including **dizziness**, **headaches**, and **fatigue**. No, don't take Gralise (gabapentin) with any other form of gabapentin, such as immediate-release gabapentin (Neurontin) or Horizant (gabapentin enacarbil). Taking more than one form of gabapentin at the same time puts you at risk for serious side effects like sleepiness, dizziness, and suicidal thoughts and behaviors. Key Differences: Pregabalin (Lyrica) vs. Gabapentin (Neurontin) Generic Drug and Brand Names. The generic drug gabapentin is available under the brand names Neurontin, Gralise, and Horizant. Gralise and Horizant are the extended-release formulations of gabapentin. HORIZANT provides approximately dose-proportional and extended exposure to gabapentin over the range 300 to 6,000 mg. HORIZANT and gabapentin are not interchangeable because the same daily dose of each results in different plasma concentrations of gabapentin. Gralise is another gabapentin product. Like Horizant, it’s a brand-name-only, ER tablet that lasts longer in the body than IR gabapentin. It’s approved to treat postherpetic neuralgia in adults. It contains the same active ingredient as IR gabapentin (it’s not a prodrug like Horizant).
