Active clinical trials for "Neuralgia"

The purpose of this trial is to determine if XPF-002 is safe and effective for the treatment of pain in subjects with Postherpetic Neuralgia

The primary purpose is to study the predictive value of preserved nociceptors and large afferent fibers and dynamic mechanical allodynia on the effect of lidocaine patch. The primary outcome measure is the predictive role for these three measures for obtaining a response to lidocaine. A responder is defined as a person with at least a 2-point pain reduction to lidocaine (change in median pain intensity (measured on a 10 point numeric rating scale) of pain from the baseline week to the last week of lidocaine treatment). Secondary effect variable will be efficacy of lidocaine on pain reduction (baseline week versus last week of each treatment) and pain relief (complete, good, moderate, slight, none, or worse) for spontaneous and evoked pain, and effect on ongoing pain, brush evoked allodynia, cold and warm allodynia, and pinprick hyperalgesia evaluated on each visit.

Use lay language. The aim of this study is to evaluate on pain scores (neuropathic pain questionnaire and pain numeric scale) and on quality of life, the effect of oral magnesium intake on patients with neuropathic pain comparing with patients receiving placebo,. The study drug will be taken during 4 weeks.

Symptoms that herald herpes zoster include pruritus, dysesthesia and pain along the distribution of the involved dermatome. The most distressing symptom is typically pain and the most feared complication is postherpetic neuralgia (PHN), the persistence of pain long after rash healing. PHN is defined as pain persisting more than 3 months after the rash has healed. Both, the acute pain associated with herpes zoster and the chronic pain of PHN, have multiple adverse effects on health-related quality of life. The primary objective of the trial presented is to investigate whether a 4 week semi-standardised acupuncture is non-inferior (first step) or superior (second step) to (a) the anticonvulsive drug gabapentin and (b) sham laser acupuncture in the treatment of pain associated with herpes zoster in addition to standardised analgesics. Secondary objectives include an assessment of the change of sensoric function, of long-term effectiveness, the occurrence of PHN and an evaluation of several pain specific questionnaires

The purpose of this study is to determine if Oxymorphone Extended Release is effective and safe in treating chronic pain in patients with cancer or neuropathic pain.

Objectives : to investigate the analgesic effects and safety of intradermal botulinum toxin A injection in the treatment of focal painful neuropathies (eg, postherpetic neuralgia, nerve trauma)

This study will test the efficacy and safety of two doses levels of RN624 versus placebo for the relief of pain caused by post-herpetic neuralgia (PHN).

Pliaglis™ (lidocaine and tetracaine) Cream 7%/7% is a topical local anesthetic cream that forms a pliable peel on the skin when exposed to air. When applied to intact skin, Pliaglis provides local dermal analgesia by the release of lidocaine and tetracaine from the peel into the skin. Pliaglis is currently approved in the United States for use on intact skin in adults to provide topical local analgesia for superficial dermatological procedures such as dermal filler injection, pulsed dye laser therapy, and facial laser resurfacing. This study will evaluate lidocaine and tetracaine cream 7%/7% for the treatment of pain associated with postherpetic neuralgia (PHN).

Pregabalin is an alpha-2 delta ligand approved for the treatment of neuropathic pain, however, not all patients will respond to this drug. This study will compare the efficacy of pregabalin when administered with an experimental drug PF-00489791, in patients with post-herpetic neuralgia. The efficacy of this combination will be compared to pregabalin alone.

Gabapentin and pregabalin are treatments for some types of neuropathic pain, including postherpetic neuralgia (PHN). However, these treatments usually need to be taken 3 times a day for effective pain control. The purpose of this study is to determine whether a new gabapentin tablet, which only needs to be taken once a day, is safe and effective for the treatment of postherpetic neuralgia.
