The lack of difference in seizure control is also surprising in that the median dosages of gabapentin (1,500 mg/d) and pregabalin (450 mg/d) for the study are biased in regard to expected efficacy and in relation to the maximum dosages listed in the product labels for gabapentin (3,600 mg/d) and pregabalin (600 mg/d). A systematic search strategy employing different combinations of the keywords (bipolar, mania, hypomania, gabapentin, neurontin, gralise, gabarone, fanatrex, pregabalin, lyrica) was developed and performed in five databases namely OVID Medline, PubMed, ProQuest, PsychInfo and ScienceDirect from database inception to 7 June 2021. Newer anticonvulsants such as Gabapentin and Pregabalin have been proven beneficial in patients with peripheral neuropathic pain. Aims and Objectives: The aim of the study was to compare the efficacy of Gabapentin and Pregabalin in relieving the pain in patients of DPN. This meta-analysis aims to evaluate and compare the effectiveness and safety of pregabalin vs. gabapentin in managing neuropathic pain. Methods: This study followed PRISMA guidelines and employed the PICOS search strategy. Pregabalin showed superior results compared to gabapentin in the Visual Analog Scale (VAS) at various time intervals up to 12–14 weeks (SMD −0.47, 95% CI −0.74 to −0.19). The results of this analysis support the notion that there is no significant difference in meaningful pain reduction with gabapentin versus pregabalin. This study demonstrates that pregabalin may afford better tolerability and lower pill burden compared to gabapentin. The results of the meta-analysis showed that the PGIC score for pain in patients taking pregabalin and gabapentin was significantly improved compared with the placebo group, with the RR of the pregabalin group being 0.44 (95% CI 0.33–0.56, P < 0.05), as shown in Fig. 4A, and that of the gabapentin group being 0.18 (95% CI 0.12–0.23, P < 0. 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). We would like to show you a description here but the site won’t allow us. In particular as regards pregabalin, three studies compared pregabalin versus placebo21, 27, 29 and one compared limaprost versus pregabalin versus an association of both drugs in a three-arm trial. 28 Regarding gabapentin trials, one study compared this gabapentinoid with placebo, 20 one with no matched intervention, 31 and one compared tramadol versus gabapentin plus tramadol. 30 Double-blind randomised controlled trials (RCTs) that compared the efficacy of gabapentin or pregabalin with placebo in patients with fibromyalgia (aged 18 years or above) were eligible for inclusion. Methods: This clinical trial was conducted on 40 patients diagnosed with CIDP randomly allocated to treatment with 100-500 mg gabapentin (n=20) or 50-300 mg pregabalin (n=20) both co-medicated with 37.5 mg venlafaxine. The dose of gabapentin/pregabalin was adjusted based on the patient’s tolerability/response to the treatment. This randomized clinical trial of pregabalin vs gabapentin in 18 patients with chronic sciatica found that gabapentin was superior to pregabalin with greater reduction of leg pain intensity and fewer adverse events. Pregabalin (PGB) and gabapentin (GBP) are recommended as the first-line treatment for neuropathic pain due to SCI [18, 19]. Both drugs have been shown to be effective in the treatment of neuropathic pain due to postherpetic neuralgia [20 – 26] and diabetic peripheral neuropathy [24 – 29]. Pregabalin and gabapentin share a similar mechanism of action, inhibiting calcium influx and subsequent release of excitatory neurotransmitters; however, the compounds differ in their pharmacokinetic and pharmacodynamic characteristics. Gabapentin is absorbed slowly after oral administration, with m Keywords: Gabapentin, pregabalin, pain management, adverse effects, pharmacology. Introduction. The gabapentinoid drugs gabapentin and pregabalin are antiepileptic drugs that are considered as first-line treatments for the management of neuropathic pain. 1 Pregabalin is also approved for generalised anxiety disorders in the United Kingdom. The Conclusions and relevance: Pregabalin and GBP were both significantly efficacious. However, GBP was superior with fewer and less severe adverse events. Gabapentin should be commenced before PGB to permit optimal crossover of medicines. Trial registration: anzctr.org.au Identifier: ACTRN12613000559718. Unlike gabapentin, they also reported a dose response, with a greater response being seen in those taking 600 mg daily than in those taking 300 mg . Pregabalin has also been shown to decrease health care and non–health care costs compared with gabapentin in the treatment of peripheral neuropathic pain . Gabapentin and pregabalin are structurally related compounds with recognized efficacy in the treatment of both epilepsy and neuropathic pain. The pharmacological mechanisms by which these agents exert their clinical effects have, until recently, remained unclear. The interaction of gabapentin and pr This is the first trial aimed at comparing gabapentin with pregabalin in NLBP. Although the results are preliminary, in our pilot study pregabalin was found to be superior in pain reduction, gabapentin demonstrated better effect on anxiety, insomnia and fatigue symptoms.
