Newest firstBACKGROUND: Neuropathic pain (NP) is a chronic and debilitating condition that remains difficult to treat, with opioids like morphine often leading to tolerance and reduced efficacy over time. Cannabidiol (CBD) has emerged as a potential therapeutic for NP even in morphine tolerance conditions; however, its effects on nociceptive modulation and neurotransmitter metabolism in morphine-tolerant NP models remain poor…
Open article record in new tab ↗Background Chronic neuropathic pain (CNP) involves complex interactions between resident and peripheral immune cells, as well as modulation of the endocannabinoid system. Cannabis-based products have emerged as promising therapeutic options, but their effects on immune cells remain unclear. This study evaluated the effects of a cannabidiol (CBD)-enriched Cannabis sp. extract administered via the oral mucosa in a C…
Prescription opioid misuse is a significant public health concern among individuals with chronic pain. Treating severe pain often requires high doses of opioids, increasing the risk of developing an opioid use disorder. Cannabidiol (CBD) is a non-intoxicating component of cannabis that has shown therapeutic potential without abuse liability. This study investigated the effects of CBD on oxycodone self-administrati…
Background Although fibromyalgia is a disabling disease, there is no targeted therapy for specific neurotransmitters or inflammatory mediators. Our aim was to provide neurologists with practical guidance for the management of these difficult patients based on a critical, narrative and non-systematic review of randomized controlled trials (RCTs) from the last 10 years. Methods The members of the Special Interest Gr…
Neuropathic pain resulting from injury to the somatosensory nervous system affects approximately 6.9-10% of the general population and significantly impacts quality of life. Common presentations include burning, stabbing, tingling, or electrical sensations, occurring spontaneously or through hyperalgesia or allodynia. Treatment approaches follow a tiered system. First-line therapies include gabapentinoids (e.g., g…
Inflammation is the critical component of neuropathic pain; therefore, this study aimed to assess the potential anti-inflammatory effects of Cannabis sativa L. extracts in a vincristine-induced model of neuropathic pain. The effects of different doses (5.0-40.0 mg/kg) of two Cannabis sativa L. extracts (B and D) on COX-1, COX-2, TNF-α, and NF-κB mRNA and protein levels were examined in the rat hippocampus, cerebra…
Chronic low back pain (CLBP) affects over half a billion people worldwide. Current pharmacologic treatments offer limited efficacy and carry substantial risks, warranting the development of safe and effective alternatives. This multicenter, randomized, placebo-controlled phase 3 trial evaluated the efficacy and safety of VER-01 in CLBP. It enrolled 820 adults with CLBP (VER-01, n = 394; placebo, n = 426) and inclu…
Development of paclitaxel-induced neuropathic pain (PINP) during chemotherapy may lead to paclitaxel discontinuation, potentially compromising effective anticancer therapy. PINP can manifest as allodynia. One recently discovered key factor in paclitaxel-induced mechanical allodynia (PIMA) pathogenesis is the elevated activity of monoacylglycerol lipase (MAGL), an enzyme that metabolizes the endocannabinoid 2-arach…
Open article record in new tab ↗Neuropathic pain is a clinically challenging syndrome that is largely refractory to conventional therapies. It arises from lesions or diseases affecting somatosensory pathways, which trigger extensive neuroplastic and neuroimmune remodeling. Unlike nociceptive pain, which establishes a protective response to tissue injury, neuropathic pain arises from maladaptive signaling within the nervous system. In this contex…
Neuropathic pain is a complex and challenging condition that arises from abnormal processing of somatosensory information, often following nerve injury or dysfunction. Its diagnosis involves a detailed clinical history, sensory examination, and diagnostic tests such as electromyography, nerve conduction studies, and MRI to identify nerve damage or structural causes. In athletes, neuropathic pain can result from ne…
Open article record in new tab ↗Background Chronic neuropathic pain (CNP) is a debilitating condition, often refractory to currently available drugs. Understanding biochemical alterations in peripheral tissues such as blood will be useful for understanding underlying pathophysiological processes relating to CNP. Methods We collected blood from two independent cohorts of CNP and pain-free controls (CNP n = 129/Controls n = 127) in the UK and Irel…
Background Disordered autonomic nervous system regulation and supraspinal pain inhibition have been repeatedly described in chronic pain. We aimed to explore the effects of δ-9-tetrahydrocannabinol (THC), an emerging treatment option, on autonomic nervous system and central pain modulation measures in patients with chronic pain. Methods Twelve male patients with chronic radicular neuropathic pain participated in a…
Chronic pain conditions affect nearly 20% of the population in the United States. Current medical interventions, such as opioid drugs, are effective at relieving pain but are accompanied by many undesirable side effects. This is one reason increased numbers of chronic pain patients have been turning to Cannabis for pain management. Cannabis contains many bioactive chemical compounds; however, current research look…
Cannabis sativa L. (hemp) is a herbaceous plant rich in cannabinoids with a long history of use in pain treatment. The most well-characterized cannabinoids, cannabidiol (CBD) and Δ9-tetrahydrocannabinol (Δ9-THC), garnered much attention in chemotherapy-induced peripheral neuropathy (CIPN) treatment. However, few studies have investigated the biological benefits and mechanism of hemp extract on CIPN. In the present…
The transcription repressor REST in the dorsal root ganglion (DRG) is upregulated by peripheral nerve injury and promotes the development of chronic pain. However, the genes targeted by REST in neuropathic pain development remain unclear. The expression levels of four opioid receptor genes (Oprm1, Oprd1, Oprl1 and Oprk1) and the cannabinoid CB1 receptor (Cnr1) gene in the DRG regulate nociception. In this study, w…
Post-traumatic trigeminal neuropathy (PTTN) is a sensory abnormality caused by injury to the trigeminal nerve during orofacial surgery. However, existing analgesics are ineffective against PTTN. Abnormal microglial activation in the caudal part of the spinal trigeminal nucleus caudal part (Sp5C), where the central trigeminal nerve terminals reside, plays an important role in PTTN pathogenesis. Therefore, regulatin…
Purpose of review This manuscript summarizes novel clinical and interventional approaches in the management of chronic, nociceptive, and neuropathic pain. Recent findings Pain can be defined as a feeling of physical or emotional distress caused by an external stimulus. Pain can be grouped into distinct types according to characteristics including neuropathic pain, which is a pain caused by disease or lesion in the…
Introduction Cannabis sativa L. (CSL) extract has pain-relieving potential due to its cannabinoid content, so the effects of two CSL extracts on alleviating neuropathic pain were investigated in vivo. Methods and groups: Male Wistar rats (n = 130) were divided into groups and received vincristine (0.1 mg/kg) and gabapentin (60 mg/kg) to induce and relieve neuropathic pain or CSL extracts (D and B). The mRNA and pr…
The rostral agranular insular cortex (RAIC) has been associated with pain modulation. Although the endogenous cannabinoid system (eCB) has been shown to regulate chronic pain, the roles of eCBs in the RAIC remain elusive under the neuropathic pain state. Neuropathic pain was induced in C57BL/6 mice by common peroneal nerve (CPN) ligation. The roles of the eCB were tested in the RAIC of ligated CPN C57BL/6J mice, g…
The role of endogenous cannabinoids in neuropathic pain has been actively studied, among which 2-arachidonoyl glycerol (2-AG) has received the most attention. However, owing to its chemical properties, direct detection of 2-AG distribution in tissues is difficult. Moreover, although desorption electrospray ionization mass spectrometry imaging (DESI-MSI) has enabled the detection of 2-AG, its distribution in the br…
