“…Topical application of 5% lidocaine medicated plaster was compared with pregabalin in patients with PHN in a randomised, open‐label, multicentre, non‐inferiority study (Baron et al, 2009). Lidocaine plaster was shown to be more efficacious, was associated with fewer AEs and related discontinuations, and had greater improvements in patient satisfaction and QOL.…”

BackgroundClinical trials have not yet compared the efficacy of capsaicin 8% patch with current standard therapy in peripheral neuropathic pain (PNP).ObjectivesHead‐to‐head efficacy and safety trial comparing the capsaicin patch with pregabalin in PNP.MethodsOpen‐label, randomized, multicentre, non‐inferiority trial. Patients with PNP, aged 18–80 years, were randomly assigned to either the capsaicin 8% patch (n = 282) or an optimised dose of oral pregabalin (n = 277), and assessed for a ≥30% mean decrease in Numeric Pain Rating Scale (NPRS) score from baseline to Week 8. Secondary endpoints included optimal therapeutic effect (OTE), time‐to‐onset of pain relief and treatment satisfaction.ResultsThe capsaicin 8% patch was non‐inferior to pregabalin in achievement of a ≥30% mean decrease in NPRS score from baseline to Week 8 (55.7% vs. 54.5%, respectively; Odds ratio: 1.03 [95% CI: 0.72, 1.50]). The proportion of patients achieving OTE at Week 8 was 52.1% for the capsaicin 8% patch versus 44.8% for pregabalin (difference: 7.3%; 95% CI: −0.9%, 15.6%). The median time‐to‐onset of pain relief was significantly shorter for capsaicin 8% patch versus pregabalin (7.5 vs. 36.0 days; Hazard ratio: 1.68 [95% CI: 1.35, 2.08]; p < 0.0001). Treatment satisfaction was also significantly greater with the capsaicin 8% patch versus pregabalin. TEAEs were mild‐to‐moderate in severity, and resulted in treatment discontinuation only with pregabalin (n = 24). Systemic adverse drug reactions ranged from 0 to 1.1% with capsaicin 8% patch and 2.5 to 18.4% with pregabalin.ConclusionsThe capsaicin 8% patch provided non‐inferior pain relief to an optimized dose of pregabalin in PNP, with a faster onset of action, fewer systemic side effects and greater treatment satisfaction.

“…85,87,93 Lidocaine patches are generally safe, because of their low systemic absorption, and well-tolerated adverse events (mild skin reactions such as erythema or rash). 243,244 Lidocaine patches have been used in NCP where allodynia exists. 113 It has also been used for central NCP in a patient with metastatic epidural spinal cord compression, with promising results, offering new treatment options.…”

Pharmacological Treatment of Neuropathic Cancer Pain: A Comprehensive Review of the Current Literature

et al. 2011

Neuropathic cancer pain (NCP), commonly encountered in clinical practice, may be cancer-related, namely resulting from nervous system tumor invasion, surgical nerve damage during tumor removal, radiation-induced nerve damage and chemotherapy-related neuropathy, or may be of benign origin, unrelated to cancer. A neuropathic component is evident in about 1/3 of cancer pain cases.Although from a pathophysiological perspective NCP may differ from chronic neuropathic pain (NP), such as noncancer-related pain, clinical practice, and limited publications have shown that these two pain entities may share some treatment modalities. For example, co-analgesics have been well integrated into cancer pain-management strategies and are often used as First-Line options for the treatment of NCP. These drugs, including antidepressants and anticonvulsants, are recommended by evidence-based guidelines, whereas, others such as lidocaine patch 5%, are supported by randomized, controlled, clinical data and are included in guidelines for restricted conditions treatment. The vast majority of these drugs have already been proven useful in the management of benign NP syndromes. Treatment decisions for patients with NP can be difficult. The intrinsic difficulties in performing randomized controlled trials in cancer pain have traditionally justified the acceptance of drugs already known to be effective in benign NP for the management of malignant NP, despite the lack of relevant high quality data. Interest in NCP mechanisms and pharmacotherapy has increased, resulting in significant mechanism-based treatment advances for the future. In this comprehensive review, we present the latest knowledge regarding NCP pharmacological management. n INTRODUCTIONFollowing EFIC's (European Federation of IASP Chapters) declaration in 2001, pain is not a symptom but a disease in its own right, necessitating appropriate treatment. The word pain usually refers to a discrete sensory experience, triggered by an identifiable set of ''painful'' stimuli, acting on a unique or stable ''pain'' pathway and eliciting an invariant sensation. However, pain, and particularly neuropathic pain (NP) can also exist as a diverse group of complex phenomena of unpleasant and distressing nature. NP encloses numerous complicated neurobiologic constituents and reflects potentially dynamic mechanisms, interacting at multiple neuraxial sites. 1Modern neurobiological techniques have led to tremendous progress in the exploration of pain pathogenetic mechanisms. [2][3][4] Research indicates that pain can be produced in multiple ways, at different locations, co-existing between and across various pathological conditions. 5,6 Novel therapeutic targets have been discovered and are used by the pharmaceutical industry for the construction of highly specific molecules, acting as potential innovative analgesics. Recent targets' application, specific to precise NP mechanisms, will very soon enable treatment to be focused at particular mechanisms, introducing a mechanism-based therap...
