Objective: Gabapentin immediate release (GBP-IR), gabapentin gastric retentive (GBP-GR), and the prodrug gabapentin enacarbil extended release formulation (GEn) have been approved for management of postherpetic neuralgia (PHN) in adults. This is the first pharmacokinetic (PK) comparison of all three formulations using FDA-recommended doses for PHN. Gabapentin enacarbil is absorbed in the intestines by active transport through the proton-linked monocarboxylate transporter, MCT-1. Volume of distribution The volume of distribution is 76L. Protein binding Gabapentin plasma protein binding is less than 3%. Metabolism Gabapentin enacarbil does not interact with any of the major cytochrome P450 Gabapentin enacarbil (GEn) is an actively transported prodrug of gabapentin that provides sustained dose-proportional exposure to gabapentin and predictable bioavailability. Gabapentin enacarbil is approved by the US Food and Drug Administration for the treatment of moderate-to-severe primary restle The data suggest that dosage adjustment for gabapentin enacarbil is necessary in patients with impaired renal function. Gabapentin enacarbil, 600 mg, seemed to be well tolerated in this small selected population. Cautions for Gabapentin Contraindications Gabapentin: Known hypersensitivity to gabapentin or any ingredient in the formulation. Gabapentin enacarbil: Manufacturer states none known. Warnings/Precautions Sensitivity Reactions Drug Reaction with Eosinophilia and Systemic Symptoms/Multiorgan Hypersensitivity Drug reaction with eosinophilia and systemic symptoms (DRESS), also known as multiorgan The absorption and bioavailability of oral gabapentin are associated with a high degree of interindividual variability. Gabapentin enacarbil, a prodrug of gabapentin, is well absorbed and provides sustained, dose-proportional exposure to gabapentin. Gabapentin enacarbil is a transported prodrug of gabapentin that was developed to overcome the pharmacokinetic deficiencies of gabapentin. It has demonstrated efficacy and safety in treating Restless Leg Syndrome (RLS) in numerous clinical trials, with patients reporting sustained improvements in symptoms' severity. Gabapentin enacarbil is a carbamate ester that is the N- [1- (isobutyryloxy)ethoxy]carbonyl derivative of [1- (aminomethyl)cyclohexyl]acetic acid. The prodrug for gabapentin, used for treatment of neuropathic pain and restless legs syndrome. Gabapentin enacarbil is a long acting form of gabapentin that is used for restless leg syndrome and for painful postherpetic neuropathy. Gabapentin enacarbil and gabapentin are associated with a low rate of transient serum enzyme elevations during treatment and with rare instances of clinically apparent liver injury. Gabapentin enacarbil is converted to gabapentin during absorption, before reaching the systemic circulation. 16 Gabapentin produced by hydrolysis of gabapentin enacarbil is also eliminated by the renal clearance pathway, without further metabolism. 16, 17 In patients with normal CrCL (≥60 mL/min), CL R after oral administration of gabapentin Gabapentin enacarbil is licensed for restless leg syndrome in the United States. 17 GBP-GR is administered once daily and gabapentin enacarbil is administered in two divided doses. 18 GBP-GR exhibits saturable absorption similar to immediate-release gabapentin but this is enhanced by high-fat content in meals. 18 Pharmacokinetic comparisons immediate release: a gastric retentive formulation (GBP-GR) and a gastro-retentive prodrug gabapentin enacarbil that are approved for the management of postherpetic Abstract Gabapentin enacarbil (GEn) is an actively transported prodrug of gabapentin that provides sustained dose-proportional exposure to gabapentin and predictable bioavailability. Gabapentin enacarbil is approved by the US Food and Drug Administration for the treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults. Gabapentin enacarbil is a transported prodrug of gabapentin that provides sustained, dose-proportional exposure to gabapentin by taking advantage of high-capacity transport pathways expressed throughout the intestinal tract. This prodrug has shown efficacy in multiple clinical trials for the treatment of moderate-to-severe primary restless legs syndrome and could potentially represent the Gabapentin enacarbil is a prodrug of gabapentin (Neurontin®, Pfizer) which binds to the α2-δ subunit of L -type voltage-regulated calcium channels, reducing the release of several neurotransmitters. 122,123 Gabapentin enacarbil was discovered at XenoPort, co-developed with GlaxoSmithKline, is marketed under the brand name Horizant®, and is approved for the treatment of moderate to severe dexmethylphenidate increases effects of gabapentin enacarbil by decreasing metabolism. Minor/Significance Unknown. levocarnitine gabapentin enacarbil decreases levels of levocarnitine by unspecified interaction mechanism. Minor/Significance Unknown. pancuronium gabapentin enacarbil decreases effects of pancuronium by pharmacodynamic antagonism. Gabapentin enacarbil is converted to gabapentin during absorption, before reaching the systemic circulation. 16 Gabapentin produced by hydrolysis of gabapentin enacarbil is also eliminated by the renal clearance pathway, without further metabolism.16, 17 In patients with normal CrCL (≥60 mL/min), CL R after oral administration of gabapentin Gabapentin is available in 2 forms—gabapentin immediate release and the prodrug gabapentin enacarbil. Gabapentin is available in tablet form with strengths of 600 mg and 800 mg, capsules in strengths of 100 mg, 300 mg, and 400 mg, as well as an oral solution of 250 mg/5mL. Gabapentin enacarbil is a prodrug of gabapentin that is rapidly converted to gabapentin following oral administration; the therapeutic effects of gabapentin enacarbil are attributed to gabapentin. Includes Gabapentin Enacarbil indications, dosage/administration, pharmacology, mechanism/onset/duration of action, half-life, dosage forms, interactions, warnings, adverse reactions, off-label uses and more.
