Active clinical trials for "Neuralgia"

Neuropathic pain is caused by a virus commonly associated with chicken pox. This virus may become dormant in the nervous system and later reactivate causing herpes zoster, also known as "shingles". Post-herpetic neuralgia (PHN) is a persistent pain in the area of healed skin lesions. This study will test the safety and efficacy of treating PHN patients with the analgesic patch, Bupivacaine TTS (Eladur™).

The objective of this study is to investigate the safety and efficacy of an investigational drug, V3381, for the treatment of diabetic peripheral neuropathic (DPN) pain (pain in one's feet and legs, or even in one's hands and arms, sometimes experienced by people with diabetes). An investigational drug is one that is not approved by the United States Food and Drug Administration (FDA) and/or Health Canada.

The purpose of the study is to assess the efficacy and safety of NGX-4010 applied for 60 minutes for the treatment of postherpetic neuralgia (PHN).

The purpose of the study is to evaluate the safety and efficacy of NGX-4010 administered at intervals of no less than 12 weeks over 1 year, based on the presence or return of pain, for the treatment of painful HIV-AN and PHN. Participation is limited to former study subjects from previous trials of NGX-4010 at selected sites.

Efficacy and Safety of flexibly dosed pregabalin compared to placebo among subjects with central post stroke pain (CPSP)

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 or twice a day, is safe and effective for the treatment of postherpetic neuralgia.

Effective treatment of neuropathic foot pain in diabetic patients is very important to improve their quality of life. There are many medications used to reduce the diabetic neuropathic pain, including anticonvulsants, anti-depressants or analgesics, but none is universally satisfied. A few previous studies employing BOTOX® i.d. injection for control of trigeminal neuralgia, post-herpes neuralgia indicate that BOTOX® was effective in controlling neuropathic pain. Intradermal injection of BOTOX® to the dorsum of the foot in diabetics should be effective in controlling diabetes-associated polyneuropathic pain of the foot.

To evaluate the efficacy and safety of pregabalin administered twice a day compared to placebo in reducing pain in subjects with painful diabetic peripheral neuropathy.

The purpose of this study is to evaluate the pain-relieving effects of venlafaxine hydrochloride (Effexor) in chronic neuropathic (burning, shock-like, electric) pain after spinal cord injury (SCI). Although a number of medications have been used to treat SCI pain, no drug has been consistently helpful, and, therefore, many people with SCI continue to have difficult chronic pain. Venlafaxine is a new anti-depressant drug that has not been tested for use in SCI neuropathic pain, but has been helpful for other types of neuropathic pain.

To evaluate the efficacy of pregabalin, using a flexible, optimized dose schedule with dose adjustment based on Daily Pain Rating Scale (DPRS), compared to placebo in subjects with peripheral neuropathic pain.
