Switching between gabapentin and pregabalin for neuropathic pain. If treatment is not effective or tolerated, NICE guidance for neuropathic pain in adults recommends switching to an alternative treatment (1) may include switching between the gabapentinoids: gabapentin and pregabalin (1) Gabapentin and pregabalin both require dose adjustment in individuals with reduced renal function. Consult the summary of product characteristics (SmPC) for gabapentin and pregabalin for further information before determining an equivalent dose and switching strategy. 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 Pregabalin and gabapentin are anticonvulsant medications primarily used to treat nerve-related conditions. Both are structurally similar and have a similar mechanism of action. Gabapentin is commonly prescribed for conditions like neuropathic pain, postherpetic neuralgia, and seizure disorders. Several studies reviewing conversion of gabapentin to pregabalin predict that a rough ratio for conversion is about 6:1 gabapentin to pregabalin. In addition, a direct switch from gabapentin to pregabalin seems to be well tolerated, making the conversion simple. pregabalin dose and titrating up the gabapentin dose. Pregabalin total daily dose pre-switch Gabapentin total daily dose post switch (Toth study8) Suggested daily dose of gabapentin 150mg 900mg 300mg tds 225mg 901mg to 1500mg 400mg tds 300mg 1501mg to 2100mg 2x300mg tds 450mg 2101mg to 2700mg 2x400mg tds Two different gabapentin to pregabalin transition designs were simulated based on their respective population pharmacokinetic profiles. The first design involved immediate discontinuation of gabapentin therapy with initiation of pregabalin therapy at the next scheduled dose period. erent ways of switching between pregabalin and gabapentin. Below is a method for direct switching bet. peripheral neuropathic pain as a second or third therapy. Duloxetine is licensed in the UK at a maximum dose of 120mg a day. One group of drugs, collectively referred to as gabapentinoids, have become useful tools for the hospice clinician, specifically gabapentin (Neurontin) and pregabalin (Lyrica). N.B. Concurrent use of gabapentin and pregabalin is not funded. 15. For information on alternative medicines for neuropathic pain, see: nzf.org.nz/nzf_2556#nzf_70735. If treatment has been ineffective or adverse effects are intolerable, gradually discontinue pregabalin or gabapentin and/or switch to an alternative medicine. 17 There are no validated dose conversions between gabapentin and pregabalin due to differences in pharmacokinetics and varying efficacy seen in studies. However, some authors have proposed dose conversions based on these parameters (see Tables 1 and 2). One switching method suggests daily doses of gabapentin between 901 to 1,500 mg/day should be converted to pregabalin 225 mg/day in two divided Pregabalin or Gabapentin (note 1) Switch to the one which was not used first (gabapentin or pregabalin) if not tolerated Dose Titration Notes Pregabalin Initially 150mg in 2-3 divided doses. Max. 600mg daily Aim for twice a day dosing with pregabalin (benefit cost and compliance). maximum of 600mg/day after (150mg bd - £12.12) see appendix 1 replace gabapentin 600mg three times a day with pregabalin 200mg twice a day replace gabapentin 900mg three times a day with pregabalin 200mg twice a day (Note: switch to pregabalin 200mg twice a day is recommended from both 600mg and 900mg three times a day of gabapentin). The dose of pregabalin can be further increased Pregabalin (Lyrica) and gabapentin (Neurontin) are medications that treat certain types of seizures and nerve pain. Pregabalin has more FDA approved uses. Both are frequently used off-label for a wide range of health conditions. When comparing pregabalin versus gabapentin, they work in similar ways but pregabalin is absorbed more quickly and fully. Ensure that gabapentin and pregabalin are prescribed at an appropriate place in therapy for neuropathic pain taking into consideration value for money. Ensure prescribed (and taken) doses of pregabalin and gabapentin are not outside the therapeutic dose range. Prescribing of pregabalin capsules should be optimised to the 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 may include switching between the gabapentinoids: gabapentin and pregabalin (1) Neuropathic pain states are typically managed by super-adding anticonvulsant drugs onto simple drug regimens. drugs most commonly used are gabapentin (GBP) or pregabalin (PGB) 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). Daily Dose of Daily dose of pregabalin per day Dosing schedule of pregabalin gabapentin pre-switch post switch (mg/day) (mg/day) 0-900 150 75mg twice daily From the National Electronic Library for Medicines. www.nelm.nhs.uk 1 Medicines Q&As 901-1500 225 75mg in the morning and 150mg in the evening* 1501-2100 300 150mg twice daily 2101-2700 450 Conversion between Lyrica and gabapentin is generally well tolerated and direct switching minimizes potential for gaps in pain relief. In the absence of seizure history, the drugs can be directly interchanged; patients can be advised to discontinue Lyrica and begin gabapentin the following day.
