nnt gabapentin neuropathic pain gabapentin is what class of drug

Critical appraisal of included RCTs indicated that gabapentinoids are effective in reducing neuropathic pain in adults. The Neuropathic Pain Special Interest Group (NeuPSIG) has recommended antiepileptic drugs to manage neuropathic pain [1]. In a Cochrane Database review of morphine vs placebo for chronic neuropathic pain in adults, Cooper et al. found only a moderate (30%) improvement in neuropathic pain, which was experienced by 63% of patients, and the NNT to achieve this moderate reduction in pain was 3.7 (2.6–6.5) . Cooper concluded that there is insufficient high-quality The present work aimed to update the recommendations of the Special Interest Group on Neuropathic Pain (NeuPSIG) of the International Association for the Study of Pain (IASP) (www.neupsig.org) on the systemic and topical pharmacological treatments of neuropathic pain. 19 Non-pharmacological management such as neurostimulation techniques were N.B. Indication = peripheral neuropathic pain: 1–4 patches to the painful area for 30–60 min every 3 months: WEAK: Moderate–high N.B. Potential safety concerns over sensation with long–term use: Moderate–high: Lidocaine plasters N.B. Indication = peripheral neuropathic pain: 1–3 5% plasters to region of pain one per day for up to 12 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). The NNT for effective pain relief in diabetic neuropathy was 2.9 (95% CI 2.2 to 4.3) and for post herpetic neuralgia 3.9 (95% CI 3 to 5.7). Authors' conclusions: There is evidence to show that gabapentin is effective in neuropathic pain. There is limited evidence to show that gabapentin is ineffective in acute pain. From each study we extracted information as described earlier [31].NNT for 50% pain intensity reduction (alternatively, 30% pain reduction or at least good pain relief) was the primary effect measure [61], and NNH was calculated as the number of patients that needed to be treated for one patient to drop out due to adverse effects. 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 diabetic neuropathy. Gabapentin provides pain relief of a high level in about a third of people who take if for painful neuropathic pain. Adverse events are frequent, but mostly tolerable. More conservative estimates of efficacy resulted from using better definitions of efficacy outcome at higher, clinically important, pain, post-traumatic or post-surgical neuropathic pain including plexus avulsion and complex regional pain syndrome type 2 (which was generally subsumed into post-traumatic or post-surgical neuropathic pain), central post-stroke pain, spinal cord injury pain, and multiple-sclerosis-associated pain. Neuropathic pain pertaining to 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 diabetic neuropathy. Thirty-seven studies (5633 participants) studied oral gabapentin at daily doses of 1200 mg or more in 12 chronic pain conditions; 84% of participants were in studies of postherpetic neuralgia, painful diabetic neuropathy or mixed neuropathic pain. Gabapentin at doses of 1800 mg to 3600 mg daily (1200 mg to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy. This summary uses a Cochrane review, updated in 2014, to address the efficacy of gabapentin compared with placebo to palliate neuropathic pain. 3 The Cochrane review includes 37 trials enrolling In patients with moderate or severe neuropathic pain from postherpetic neuralgia or painful diabetic neuropathy, oral gabapentin (1200-3600 mg/day for 4-12 weeks) was associated with pain reduction of at least 50% in 14-17% more patients than placebo. In patients with neuropathic pain, this review shows that gabapentin is associated with a greater likelihood of achieving substantial or moderate pain relief vs placebo. These findings permitted a strong recommendation for use and proposal as first-line treatment in neuropathic pain for tricyclic antidepressants, serotonin-noradrenaline reuptake inhibitors, pregabalin, and gabapentin; a weak recommendation for use and proposal as second line for lidocaine patches, capsaicin high-concentration patches, and For people with neuropathic pain. Gabapentin at a dose of 1800 to 3600 mg daily (1200 to 3600 mg gabapentin encarbil) can provide good levels of pain relief to some people with postherpetic neuralgia and peripheral diabetic neuropathy. Evidence for other types of neuropathic pain is very limited. One other review has provided NNTs for gabapentin in different neuropathic pain conditions based on 50% pain relief, quoting NNTs of 4.7 and 4.3 for neuropathic pain and peripheral pain, and 4.6 and PHN and 3.9 for PDN (Finnerup 2005). Statistically significant pain relief (assessed as ≥ 30% pain reduction over baseline) was achieved with gabapentin (daily dose 2400 mg) compared to placebo over 12 weeks with RR (95% CI) of 1.6 (1.1 to 2.4) and corresponding NNT (95% CI) of 5.4 (2.9 to 31).
