INTRODUCTION: Pain can affect people regardless of age, gender or ethnicity. Chronic central neuropathic pain (CCNP) is a debilitating condition that affects populations such as stroke survivors, amputees, spinal cord injury patients and patients with multiple sclerosis, with prevalence rates between 30% and 80%. This condition can be caused by a lesion or disease affecting the somatosensory system. CCNP is notoriously drug resistant, and few effective CCNP treatment or management strategies exist...

Leflunomide, an immunosuppressive drug approved for the treatment of patients with rheumatoid arthritis, exhibits many mechanisms which may affect the nociceptive processing. Therefore, the present study aimed to evaluate the effect induced by leflunomide on the mechanical allodynia in models of inflammatory and neuropathic pain in mice and investigate mechanisms mediating such effects. Per os (p.o.) administration of leflunomide (25, 50 or 100 mg/kg) inhibited the inflammatory edema and mechanical allodynia induced by intraplantar carrageenan...

BACKGROUND AND AIM: The FOLFOX family of chemotherapy regimens are hampered by the development of a painful neuropathy. Current clinical treatments are inadequate, and furthermore, the research of innovative drugs is strongly disadvantaged by the absence of a preclinical model based on the complete mixture of FOLFOX components. The aim of this study was to set up a rat model of FOLFOX-induced neuropathy in rats, validate its predictability by reference drugs, and evaluate the effectiveness of the new anti-neuropathic compound dimiracetam...

Gabapentin (Neurontin) and Pregabalin (Lyrica) are first and second-generation α2δ [1,2] ligands, respectively, and are both approved for use as adjunctive therapy in pain control. Although they do not bind to gamma-aminobutyric acid (GABA) receptors they have been successfully used to treat neuropathic pain conditions. Their mechanism of action is not yet fully understood, but research has demonstrated promising results. Despite their similarities, they have been used in combination in both clinical and research situations, and have been noted to have a synergistic effect in pain control without concern for clinically significant pharmacokinetic interactions...

The treatment of neuropathic pain is very complex and there are few drugs approved for this purpose. Among the studied compounds in the literature, sigma-1 receptor antagonists have shown to be promising. In order to develop QSAR studies applied to the compounds of 1-arylpyrazole derivatives, multivariate analyses have been performed in this work using partial least square (PLS) and artificial neural network (ANN) methods. A PLS model has been obtained and validated with 45 compounds in the training set and 13 compounds in the test set (r(2)training = 0...

Understanding of the causes and underlying mechanisms of pain in people with RA is rapidly changing. With the advent of more effective disease modifying drugs, joint inflammation is becoming a more treatable cause of pain, and joint damage can often be prevented. However, the long-term prognosis for pain still is often unfavourable, even after inflammation is suppressed. Pain is associated with fatigue and psychological distress, and RA pain qualities often share characteristics with neuropathic pain. Each of these characteristics suggests key roles for central neuronal processing in RA pain...

Although inflammation-induced peripheral sensitization oftentimes resolves as an injury heals, this sensitization can be pathologically maintained and contribute to chronic inflammatory pain. Numerous inflammatory mediators increase the production of reactive oxygen (ROS) and nitrogen species (RNS) during inflammation and in animal models of chronic neuropathic pain. Our previous studies demonstrate that ROS/RNS and subsequent DNA damage mediate changes in neuronal sensitivity induced by anticancer drugs and by ionizing radiation in sensory neurons, thus we investigated whether inflammation and inflammatory mediators also could cause DNA damage in sensory neurons and whether that DNA damage alters neuronal sensitivity...

Breast cancer is the most common cancer among women worldwide, and survival rates are increasing. Chemotherapy-associated peripheral neuropathy (PN) is clinically important because of effects on quality of life (QOL) and potential effects on dose limitations. This adverse drug reaction is associated with certain classes of chemotherapy and commonly presents as peripheral sensory neuropathy whose natural course is largely unknown. The literature was reviewed to determine the frequency and characteristics of PN associated with adjuvant chemotherapy in early-stage breast cancer (ESBC) to explore the potential impact on long-term (one or more years after diagnosis) health outcomes and QOL...

BACKGROUND: The tricyclic antidepressant amitriptyline, the serotonin and noradrenaline reuptake inhibitor duloxetine, and gabapentinoids are first-line drugs for treatment of neuropathic pain. The analgesic effect of these drugs relates to brainstem-spinal descending noradrenergic systems. However, amitriptyline utilizes a variety of mechanisms for analgesia in neuropathic pain, and it is unclear which mechanism is most important. In the present study, we investigated the role of descending noradrenergic systems in the analgesic effect of these drugs for treatment of neuropathic pain...

Preclinical Research Gabapentin is an anticonvulsant used to treat neuropathic pain. Mangiferin is an antioxidant that has antinociceptive and antiallodynic effects in inflammatory and neuropathic pain models. The purpose of this study was to determine the interaction between mangiferin and gabapentin in the development and maintenance of formalin-induced secondary allodynia and hyperalgesia in rats. Gabapentin, mangiferin, or their fixed-dose ratio combination were administrated peripherally. Isobolographic analyses was used to define the nature of the interaction of antiallodynic and/or antihyperalgesic effects of the two compounds...

Simvastatin is a lipid-lowering agent that blocks the production of cholesterol through inhibition of 3-hydroxy-methyl-glutaryl coenzyme A (HMG-CoA) reductase. In addition, recent evidence has suggested its anti-inflammatory and antinociceptive actions during inflammatory and pain disorders. Herein, we investigated the effects of simvastatin in an animal model of complex regional pain syndrome-type I, and its underlying mechanisms. Chronic post-ischemia pain (CPIP) was induced by ischemia and reperfusion (IR) injury of the left hind paw...
