Gabapentin and pregabalin belong to the same class of medicines — gabapetinoids. So, there are a lot of similarities between them. They both work in a similar way, although researchers aren't While gabapentin (Neurontin) and pregabalin (Lyrica) share many similarities, there are a few things that set them apart. We’ll highlight seven key differences between these medications below. 1. Pregabalin is FDA approved for more uses than gabapentin, but both are often used off-label. Gabapentin is indicated as adjunct therapy for partial seizures and postherpetic neuralgia. 4 Pregabalin is indicated for the same uses as gabapentin, plus the management of fibromyalgia and neuropathic pain associated with diabetes, specifically diabetic neuropathy. 5 Gabapentin and pregabalin are antiepileptic drugs commonly used for neuropathic pain management and pain reduction in adults. Both medications are classified as antiepileptic medications, but they have differences in pharmacokinetics, safety profile, and clinical applications. Compare Gabapentin vs Pregabalin head-to-head with other drugs for uses, ratings, cost, side effects and interactions. Researchers publishing in JAMA Neurology describe the results of a unique trial in which 402 people with idiopathic sensory polyneuropathy were randomly assigned to one of four medications: duloxetine, mexiletine, nortriptyline, or pregabalin. After 12 weeks, each person rated their neuropathy symptoms on a scale from 1 to 10, noted any side Concerning the elderly, untreated persistent pain is associated with poor sleep, social isolation, functional deterioration and increased risk of falls . Anticonvulsants, such as pregabalin and gabapentin, as a first line therapy for neuropathic pain have are effective also for sleep disturbances. 2. Clinical Evaluation and Diagnosis The particular NNTs for pregabalin and gabapentin were 7.71 and 7.16, respectively. 10 A more recent meta-analysis in 2022 specifically focused on post-herpetic neuralgia and found greater efficacy with pregabalin in alleviating pain and improving global perception of pain and sleep. 15 Another meta-analysis published in 2021 reported similar Examples of pain-relieving anti-seizure medications include gabapentin (Neurontin, Gralise) and pregabalin (Lyrica). Side effects of these medications are common and may include nausea, dizziness, drowsiness and a sense of tiredness. The general recommendation is to commence treatment with gabapentin/pregabalin or a tricyclic antidepressant (eg, amitriptyline or nortriptyline) and, in case of focal neuropathy, topical lidocaine. The choice between a gabapentinoid and a tricyclic is based on considerations on tolerability rather than quality or intensity of pain. Gabapentin and pregabalin are analogs of gamma-aminobutyric acid (GABA) and share a similar mechanism of action, although they differ in some aspects. Both drugs bind to the α2δ subunit of calcium channels in neurons, but pregabalin exhibits greater affinity and potency in its binding (5, 6). Pregabalin and gabapentin both resulted in moderate to large increases in cognitive effects (4.8%), dizziness (25.6%), and weight gain (10.1%); pregabalin also resulted in large increases in the Both Lyrica and gabapentin are used as anti-epileptic medications and to treat nerve pain. But there are several differences between them. The main differences between Lyrica and gabapentin are: Lyrica is a brand name for pregabalin. Gabapentin is a generic name - brands of gabapentin include Neurontin, Gralise, and Horizant. In elderly patients with renal impairment, dose adjustment of gabapentin and pregabalin is required. Carbamazepine currently is the first line therapy for neuralgia. Gabapentin and pregabalin are recommended to be taken in short courses (two to four months) for certain types of neuropathic pain including diabetic neuropathy, central neuropathic INTRODUCTION. Chronic pain is one of the most common reasons that patients seek medical attention. Chronic pain results from combined biologic, psychologic, and social factors, and most often requires a multifactorial approach to management.

Both drugs are also indicated to treat partial seizures in adults and certain children with epilepsy (a seizure disorder) when taken along with other medication. Although several different types of anticonvulsants have been shown to modulate neuropathic pain activity, the 2 most commonly used are gabapentin (Neurontin, others) and pregabalin (Lyrica). Both gabapentin and pregabalin pre-synaptically bind to the a2d-subunit on voltage-dependent calcium channels, modulating calcium influx and reducing Pregabalin is licensed for peripheral and central neuropathic pain whereas gabapentin is licensed for peripheral neuropathic pain only. Use of gabapentin for central neuropathic pain is therefore off-label. Both drugs can be used in children. Lyrica is approved to treat partial onset seizures in children ages 1 month and older, while gabapentin is approved for this use in children ages 3 years and
