For management of localised neuropathic pain including superficial, small fibre neuropathies, post herpetic neuralgia and painful diabetic peripheral polyneuropathy, consider: Localised neuropathic pain CARBAMAZEPINE – Start dose at 100mg twice daily and slowly titrate the dose based on response in steps of Neuropathic pain definition and treatment goals Neuropathic pain is either pain of nerve origin or pain that has not resolved within the normal healing time for a condition (pain which has continued for three months or longer). The goal of neuropathic pain treatment is to support initial symptomatic relief such that patients are second line treatments for peripheral neuropathic pain. The NHS Tayside guidance and algorithm for the treatment of neuropathic pain reflects the SMC advice and should be followed for the treatment of neuropathic pain within NHS Tayside. NICE clinical guidelines such as the guideline for the pharmacological management of neuropathic pain, do Guideline for managing neuropathic pain in primary care Page 4 of 11 First Produced: January 2008 Reviewed: April 2023 Next review date: March 2026 Neuropathic pain treatment pathway (Adapted from PrescQIPP bulletin 216 Neuropathic pain, 2021) (approx. cost for 6 months, DT Feb2023) Trigeminal neuralgia Use carbamazepine first line A Cochrane review of combination therapy for neuropathic pain demonstrated that gabapentin and opioids provide better pain relief than gabapentin or opioids alone, but this was associated with increased levels of adverse events. The calculated NNT was 9.5 (5.0–86), and the NNH was 10 (6.5–25). Administration of 4 different doses of gabapentin during the initial titration in outpatients with neuropathic pain resulted in a significant reduction in awakening from breakthrough pain and a reduction in the adverse effects of the medication. Gabapentin Dosing for Neuropathic Pain: Evidence from Randomized, Placebo-Controlled Clinical Trials Miroslav Backonja, MD,1 and Robert L. Glanzman, MD2 l Departments of Neurology, Anesthesiology, and Rehabilitation Medicine, University of Wisconsin Hospital and Clinics, Madison, Wisconsin, and 2pfizer lnc, New York, New York ABSTRACT Background: Pain is one of the most common reasons for Multidisciplinary conservative care and nonopioid medications (tricyclic antidepressants, serotonin norepinephrine reuptake inhibitors, gabapentanoids, topicals, and transdermal substances) are recommended as firstline therapy; combination therapy (firstline medications) and tramadol and tapentadol are recommended as secondline; serotonin-specif First line treatment can be initiated for possible neuropathic pain. If possible criteria is not satisfied it is unlikely to be neuropathic pain. Example: for radicular leg pain . Possible=pain in a specific dermatome . Probable= signs in that dermatome e.g. straight leg raise . Definite= an MRI showing nerve impingement at that level Background for FF #49: Gabapentin (Neurontin) is an antiepileptic that has FDA indication to treat postherpetic neuralgia and partial onset seizures. This Fast Fact will review gabapentin’s role in neuropathic pain. See Fast Fact #289 for a comparison of gabapentin with pregabalin, a similar neuropathic analgesic. Gabapentin was effective in the treatment of painful diabetic neuropathy, postherpetic neuralgia, and other neuropathic pain syndromes. It relieved symptoms of allodynia, burning pain, shooting pain, and hyperesthesia. for all neuropathic pain (except trigeminal neuralgia) a choice of amitriptyline, duloxetine, gabapentin or pregabalin should be offered as initial treatment for neuropathic pain (except trigeminal neuralgia) (1) from previous guidance there is some advice about titration. for amitriptyline Objectives: The goals of this article were to review data on the efficacy and tolerability of gabapentin in the treatment of neuropathic pain in adults and to determine the optimal dosing schedule. Methods: Randomized controlled studies of gabapentin for neuropathic pain were identified through a search of PubMed and MEDLINE from 1966 to the For immediate-release gabapentin (Neurontin), dosing may be initiated with 300 mg on day 1, doubled on day 2 (300 mg twice a day), and tripled on day 3 (300 mg 3 times a day). The dose can then be titrated up as needed for pain relief to a maximum dose of 1,800 mg daily (divided into 3 daily doses). Slower titration of gabapentin may be appropriate for individual patients to improve tolerability. Once a patient is on a 900mg dose, the dose can be increased in 300mg increments every two to three days until tolerated. However, the National Institute for Health and Care Excellence (NICE) recommends gabapentin as a first-line treatment option for adults with all neuropathic pain (except trigeminal neuralgia) [NICE, 2019a]. Fast titration (usually suitable for otherwise healthy younger adults). portance of dosage titration and the titration process, providing the person with individualised information and advice. A. Licensed for peripheral neuropathic pain such as painful diabetic neuropathy and post-herpetic neuralgia in adults. B. Licensed for peripheral and central neuropathic pain. C. Licensed for diabetic peripheral neuropathic pain. The established therapeutic dosing for gabapentin in neuropathic pain is 1800-3600 mg/day in 3 divided doses in patients with normal renal function. Neuropathic pain is a chronic debilitating pain syndrome that is complex to treat. Detailed Gabapentin dosage information for adults and children. Includes dosages for Restless Legs Syndrome, Epilepsy and Postherpetic Neuralgia; plus renal, liver and dialysis adjustments. Oral gabapentin dosed at 1,200 mg or more daily demonstrated a 50% reduction in pain intensity, with a number needed to treat (NNT) of eight for postherpetic neuralgia and an NNT of six for
