View clinical trials related to Postherpetic Neuralgia.
Filter by:Shingles is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chicken pox. Some people experience continued pain even after the shingles rash and blisters have healed; this pain is known as postherpetic neuralgia. The purpose of this study is to evaluate the effectiveness of a new topical treatment for postherpetic neuralgia in adults.
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)
The purpose of this study is to evaluate the safety, effectiveness, and tolerability of 200 mg of RWJ-333369 given twice daily compared with placebo in the treatment of postherpetic 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™).
This trial was the follow-on trial to a preceeding double-blind, placebo controlled trial which included patients with at least moderate pain due to postherpetic neuralgia. It was conducted at six sites in Germany and has been clinically finalized. The patients had successfully completed the above mentioned trial in postherpetic neuralgia and, in the investigator's opinion, would benefit from long-term administration of Lacosamide. After a 1-week run-in phase the patients were uptitrated to their optimal dose and then continued into the maintenance phase. Dose adjustments were allowed throughout the trial.The change in pain was measured daily as well as interference of pain with sleep and general activity. As per protocol this trial was terminated after two years of treatment.
4-month study including a 30-day baseline phase
The incidence and severity of HZ (or shingles), as well as the frequency and severity of its complications, increases markedly with increasing age. More than half of all cases occur in persons over the age of 60. Even without complications, HZ can interfere with an elderly patient's ability to perform essential activities of daily living, resulting in a loss of independence that is emotionally devastating and frequently irreversible. The most common complication of HZ in elderly persons is postherpetic neuralgia (PHN), which frequently results in disordered sleep, chronic fatigue, anxiety and severe depression. Antiviral therapy has a modest impact on the acute phase of HZ. However, it does not appear to prevent the development of PHN. This study is a 5.5 year randomized, double-blind, placebo-controlled, efficacy trial to determine whether vaccination with live-attenuated Oka/Merck varicella-zoster decreases the incidence and/or severity of herpes zoster (HZ) and its complications in adults 60 years of age and older.
