Cannabidiol induces antiallodinic and antihiperalgesic effects via D2-NFKB dopamine receptor in hemiparkinsonian male rats (Neuroscience 2025) - "Most patients with Parkinson's disease have neuropathic pain and do not receive adequate treatment or do not respond to treatment, even though there are various first-line treatments, such as tricyclic antidepressants, gabapentin, pregabalin, duloxetine and fluoxetine. There are alternative treatments such as lidocaine or capsaicin patches, opioids, and cannabis...On the other hand, we find a decrease in NFKB immunoreactivity and cytokines production. These results show that CBD has analgesic activity and exerts it effect by D2DR via NFKB in 6-OHDA-lesion male rats."

Utility Values From Pooled Analysis of High Concentration (179 mg) Capsaicin Patch (HCCP) Studies In Peripheral Neuropathic Pain (PNP) (ISPOR-EU 2025) - "This pooled analysis of clinical trials provides robust utility estimates that capture the quality-of-life impact of different pain severities in PNP. The clear separation between pain-defined utility states highlights the substantial impact of even moderate pain on patient quality of life and supports the relevance of pain-defined health states in health economic evaluations."

Real-world evidence on repeated high-concentration (179 mg) capsaicin patch (HCCP) treatment for chemotherapy-induced peripheral neuropathy (CIPN) — focusing on pain relief, quality of life (QoL) and reduced systemic analgesic use (CASPAR study) (DGHO 2025) - "The results indicate that repeated HCCP treatments may improve pain, sleep, and QoL in patients with CIPN, while reducing the need for systemic medications. Tolerability was favorable, with mostly mild local ADRs that became less frequent with repeated use."

Comprehensive insights into diabetic peripheral neuropathy: pathophysiology and therapeutic approaches. (PubMed, J Diabetes Metab Disord) - "The United States Food and Drug Administration has approved pharmacological treatments for painful diabetic peripheral neuropathy: pregabalin, duloxetine, gabapentin, extended-release tapentadol, tramadol, and the capsaicin 8% patch. Non-Food and Drug Administration-approved therapies, such as amitriptyline and the 5% lidocaine patch, are also widely used...A multifaceted approach incorporating pharmacological and non-pharmacological therapies is essential for optimizing patient outcomes in diabetic peripheral neuropathy. Targeting underlying pathophysiological mechanisms while providing symptomatic relief can enhance treatment efficacy and improve the quality of life for individuals with diabetic peripheral neuropathy."

Long-Term Efficacy and Safety of Treatments for Peripheral Neuropathic Pain: A Systematic Review (NeuPSIG 2025) - "For 4 treatments ≥5 studies with duration ≥ 6 months had been published (all 4 identified in the original search and 1 via the addendum search).The highest number of studies was recorded for high concentration (179mg) capsaicin patch (n=9; 6 with follow up >6 months) followed by duloxetine (n=7; 4 with follow up >6 months), gabapentin (n=6; 1 with follow up >6 months) and pregabalin (n=5; 3 with follow up >6 months). Although PNP is a chronic disorder often requiring long-term treatment, only 4 of the first- and second-line therapies recommended by NeuPSIG, have ≥5 published studies evaluating their long-term efficacy/effectiveness in PNP patients. A substantial evidence gap remains for all other treatments recommended for PNP in the NeuPSIG guidelines, underscoring the need for long-term research, and long-term data (with evaluation of ≥ 6 months) for future guidelines.Table 1: Original in and exclusion criteria"

QUTENZA (8% Capsaicin Plaster) Efficacy and Tolerability, an observational clinical study (NeuPSIG 2025) - "Our data will reinforce and add objectivity for the consideration of capsaicin plaster in treatment of localised neuropathic pain where conventional anti neuropathic have failed or have not been tolerated by patients. The initial results suggest increasing trend towards better patient satisfaction, reduction of sedative pain medications and improved quality of life for selected patient cohorts. We look forward to presenting our data in greater detail at the conference."

Effect of high concentration capsaicin patch (HCCP) treatment on neuropathic pain symptoms across etiologies: data from clinical practice (CASPAR) (NeuPSIG 2025) - "In this cohort of patients with PNP and largely comparable baseline characteristics, distinct symptom patterns were observed accross etiologies. Treatment with HCCP was associated with a reduction in PDQ7 item scores across etiologies. However, the extent of improvement varied among individual symptoms."

Is there benefit from treatment with a topical TRPV-1 agonist in Complex Regional Pain Syndrome (CRPS): observational cohort study (CASPAR) (NeuPSIG 2025) - "This study evaluates the effect of repeated treatment with high concentration (179 mg) capsaicin patch (HCCP) on pain intensity, sleep quality, quality of life (QoL) and daily functioning and tolerabilty in patients with CRPS under real-world clinical conditions. This retrospective cohort study is part of a broader investigation analyzing anonymized routine care data from the German Pain eRegistry... Repeated HCCP treatment in CRPS patients led to important improvements in pain intensity, sleep, QoL, and suicidal ideation in this study. Application site reactions, which were primarily mild to moderate were noted in association with the application process."

Topical treatment of chemotherapy-induced peripheral neuropathy (CIPN) with high concentration capsaicin patch (HCCP): results of an observational cohort study (CASPAR) (NeuPSIG 2025) - "Repeated HCCP treatment was associated with progressive reductions in pain intensity and neuropathic symptoms in patients with CIPN. A significant proportion of non-responders after the first treatment converted to responders following additional treatments. Improvements in all individual painDETECT® symptoms were observed, with the most notable improvement in allodynia."

Evaluation of the treatment effect of capsaicin (179mg) patch on Chronic Regional Pain syndrome (NeuPSIG 2025) - "The findings suggest that Capsaicin 179mg transdermal is an effective approach to managing localized PNP secondary to CRPS, contributing to substantial improvements in quality of life and reductions in pain interference and intensity. The treatment's ability to provide sustained relief with minimal systemic side effects makes it a valuable alternative to conventional pharmacological approaches. Findings support the use of Capsaicin 179mg as a viable option for neuropathic pain in those diagnosed with CRPS and highlights the need for further research to confirm these results in larger and more diverse patient populations."

Health Care Professionals’ Perspectives of Inadequately Managed Painful Diabetic Peripheral Neuropathy: A Qualitative Analysis (PAINWeek 2025) - "Five products have been approved by the US Food and Drug Administration (FDA) for the management of pain associated with DPN: duloxetine, pregabalin, tapentadol, capsaicin 8% patch, and spinal cord stimulation devices...The most frequently prescribed first-line therapies included gabapentin (n=16), pregabalin (n=7), topical creams (n=7), and duloxetine (n=6)... Twenty HCPs participated in the study, with an equal distribution between generalists (family medicine or internal medicine; n=10) and specialists (neurology, n=5; pain medicine, n=5). The sample was mostly male (n=13, 65%) and White (n=11, 55%). On average, participants had 24.3 years of experience managing painful DPN and reported treating between 2-50 patients with pain associated with DPN per week."

Efficacy and safety of different medications compared for the treatment of postherpetic neuralgia: a network meta-analysis. (PubMed, Front Pharmacol) - "Amitriptyline plus pregabalin demonstrated the highest probability of clinical superiority (SUCRA = 0.92). The study showed that capsaicin patches and hydromorphone were more significant in relieving pain in PHN, whereas calcium channel modulators were more comprehensive in clinical management. The inclusion of more high-quality articles was needed to support this evidence due to quality bias in the literature."
