Active clinical trials for "Neuralgia"

The purpose of this trial is to investigate the efficiency of pain relief and the safety of NPC-06 for the neuropathic pain associated with cancer, in addition to explore the effective concentration of NPC-06.

The purpose of this study is to propose a new flexible dose regimen starting from 75mg using the low dose pregabalin 25 mg and 50 mg comparing the side effect and compliance with the conventional flexible dose regimen staring from 150mg using the pregabalin 75mg.

Microvascular dysfunction underlies pain in different animal models of neuropathic pain. Pentoxifylline is a phosphodiesterase inhibitor that reduces cyclic adenosine monophosphate (cAMP) hydrolysis, enhances blood flow and reduces platelet aggregation, decreases blood viscosity, and increases the flexibility of red blood cells, all of which relieve microvascular dysfunction. Clonidine is an α2-adrenergic receptor agonist that decreases sympathetic outflow from the brainstem, vascular reactivity and has direct peripheral vasodilatory action. Topical combination of pentoxifylline and clonidine produced significant antiallodynic effects in rat models of neuropathic pain with sciatic nerve injury, painful diabetic neuropathy, and chemotherapy-induced painful neuropathy. In healthy volunteers with an experimentally-induced surrogate for neuropathic pain: post-capsaicin tourniquet exposure, the topical combination reduced areas of dynamic allodynia and mechanical hyperalgesia, in addition to reducing post-capsaicin ischemic pain. This study will investigate if the same topical combination of clonidine + pentoxifylline will relieve pain in patients with neuropathic pain following traumatic injuries of peripheral nerves.

Medically intractable pain caused by occipital neuralgia can be very difficult to control with traditional pain management. Peripheral nerve stimulation which is used in migraines and cluster headache can be an alternative for these patients with occipital neuralgias when medical treatment and traditional pain management have failed (drugs for neuropathic pain, infiltrations, psychobehavioral approaches and multidisciplinary approach in a pain center). Occipital nerve stimulation consists to put a lead subcutaneously in front of the occipital nerve and to connect the lead to a pulse generator. A retrospective study of 60 patients was conducted in Nantes University Hospital. The results were good with the Visual Analog Scale (VAS) decreased from 8.4 preoperatively to 2.85 postoperatively. The medical quantification scale (MQS) was reduced to about 50% (18 preoperatively versus 9.9 postoperatively). Stimulation was quiet stable over time with a mean follow-up of 24 months (range 6 to 72 months). The aim of StimO is to confirm this result through a national controlled randomized multicenter study where occipital nerve stimulation will be compared to the optimal medical management.

Two percutaneous procedures used in the treatment of idiopathic trigeminal neuralgia are analysed. The effects on pain relief, alterations in cutaneous sensibility and olfactory and salivatory functions are analysed as well.

The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in subjects suffering from severe chronic low back pain (LBP) who are taking WHO Step III analgesics and show lack of tolerability. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome. The trial will compare the effectiveness of previous analgesic treatment (WHO Step III) with that of tapentadol hydrochloride prolonged release treatment during defined periods of evaluation.

The primary aim of this study is to investigate if AZD1386 is efficacious as an analgesic in patients with peripheral neuropathic pain. This will be done by comparing the effect of AZD1386 to placebo ("inactive substance") on pain.

The purpose of the study is to determine the efficacy of etoricoxib on pain patients. The investigators assume that patients with neuropathic pain will have greater pain relief then patients on placebo.

The primary objective of this study is to assess the efficacy of Eslicarbazepine acetate (ESL) as therapy in subjects with Post-herpetic Neuralgia (PHN) over a 15 week treatment phase.

This study examines the safety of pregabalin over a 6 month period in patients with neuropathic pain associated with HIV infection as an extension of another trial that tests the efficacy of pregabalin.
