Learn how gabapentin and pregabalin differ in pharmacokinetics, pharmacodynamics, and indications for neuropathic pain. Find out how to convert gabapentin to pregabalin and vice versa, and what factors to consider when choosing between the two drugs. Pharmacist's Letter membership benefits include:. 12 issues every year — what you need to know and do, right now; Quick, practical reference charts and tools; Comprehensive CE library to meet license renewal and state requirements There is no established guidance on the conversion of gabapentin to pregabalin or vice versa. The product information suggests gradual discontinuation over a week, but this may not be relevant for neuropathic pain. Studies have used different conversion ratios, but these are not widely used or proven. One group of drugs, collectively referred to as gabapentinoids, have become useful tools for the hospice clinician, specifically gabapentin (Neurontin) and pregabalin (Lyrica). no clear evidence that either gabapentin or pregabalin is more effective than the other for neuropathic pain,1 patients may bene-fi t from switching. In an open-label study, analgesia improved after switching from gabapentin to pregabalin.3 There is no established guidance on converting between gabapentin and pregabalin.4 The manufacturers of both An open label study substituted gabapentin with pregabalin in patients with neuropathic pain due to peripheral neuropathy. The author describes an overnight switch from gabapentin to pregabalin, based on a conversion table which is described in the paper as “of the author’s creation” (table 1). How does pregabalin compare to gabapentin in the treatment of neuropathic pain? David F. McAuley, Pharm.D. GlobalRPh Inc. Pregabalin versus gabapentin: Pregabalin, like gabapentin, is an amino acid derivative of gamma-amino butyric acid (GABA analogue).1,2 Pregabalin is the pharmacologically active S-enantiomer of 3-aminomethyl-5-methyl-hexanoic acid, and has a similar pharmacological profile Pregabalin (Lyrica®) PGB Primidone (Mysoline®) PRM Felbamate (Felbatol®) FBM Gabapentin (Neurontin®) GBP Lacosamide (Vimpat®) LCM LamoTRIgine (Lamictal®) LTG LevETIRAcetam (Keppra®) LEV LORazepam (Ativan®) LZP ClonazePAM (Klonopin®) CZP Clorazepate (Tranxene®) CLZ DiazePAM (Valium®) DZP Eslicarbazapine (Aptiom®) ESL NO This document provides guidance on converting patients from pregabalin to gabapentin, including recommended total daily doses of gabapentin based on pregabalin dose. It also includes information on titrating the gabapentin dose, adjusting the dose based on renal function, standard and rapid titration schedules for gabapentin, maximum doses, and discontinuing gabapentin gradually over a week. Learn how to switch between gabapentin and pregabalin in adults with neuropathic pain, using a 6:1 dose equivalence ratio and different methods. Find out the considerations, interactions, and monitoring tips before switching. Systematic reviews have found moderate quality evidence to support the use of gabapentin and pregabalin in people with peripheral diabetic neuropathy and post-herpetic neuralgia. 4 Approximately 40% of people taking pregabalin (600 mg, daily) and 30% of people taking gabapentin (≥ 1,200 mg, daily) for at least eight weeks achieved ≥ 50% Previously, studies have shown 6:1 conversion factor, from gabapentin to pregabalin. (Pain Med. 2011 Jul;12(7):1112-6.) The Literature: Am J Ther. 2013 Jan;20(1):32-6.* Compared unidirectional switch from gabapentin to pregabalin with two rotation strategies: 1. Direct switch o Stop gabapentin, initiate pregabalin at next scheduled dose period Table 1: Proposed switching doses. Pregabalin is available as capsules of 25mg, 75mg and 150mg in New Zealand. Stop/start: Take the last dose of gabapentin at night and start the target dose of pregabalin the following day. Two papers utilising this approach reported that it was effective and well-tolerated.3,8. A chart showing the conversion between Lyrica and gabapentin doses for neuropathic pain. The web page also provides information on Shingrix, Admelog, and testosterone formulations. Learn how to convert gabapentin to pregabalin for neuropathic pain management. Find out the factors that affect the conversion, the dose equivalents, and the tapering strategies. This document provides a review of the literature and manufacturer's information on how to switch between pregabalin and gabapentin for neuropathic pain, and vice versa. It includes a dose conversion table from a study by Toth, but warns that there is limited evidence and no clear recommendations. Pregabalin to gabapentin dose equivalence calculation. using the 6:1 ratio an equivalent dose of gapapentinoid can be determined using a step-wise approach; determine total dose (in mg) taken by an individual in a 24-hour period; multiply total daily dose (in mg) of pregabalin by 6 to give total daily dose of gabapentin (in mg) In both studies conversion from Gabapentin to Pregabalin was achieved by discontinuation of Gabapentin therapy after an evening dose with initiation of Pregabalin therapy the following morning. Dose equivalencies of Gabapentin and Pregabalin The following conversion table was based on the assumption that Pregabalin has Both transition designs were studied at 3 dosage levels: gabapentin 900 mg/d to pregabalin 150 mg/d, gabapentin 1800 mg/d to pregabalin 300 mg/d, and gabapentin 3600 mg/d to pregabalin 600 mg/d. Overall drug exposure achieved during the 2 transition designs was the sum of the gabapentin and pregabalin concentrations, expressed as pregabalin MEDICATION*TITRATION*SCHEDULE*FOR*GABAPENTIN*&*PREGABALIN* Gabapentin 100MG (Amount of pills to take) Morning Noon Night 1st week X X 1 2nd week X 1 1 3rd week 1 1 1 4th week 1 1 2 5th week 1 2 2 6th week 2 2 2 Gabapentin 300MG (Amount of pills to take) Morning Noon Night 1st week X X 1 2nd week X 1 1 3rd week 1 1 1
