Active clinical trials for "Trigeminal Neuralgia"

Trigeminal neuralgia is a paroxysmal extreme pain and is an unmet clinical need, we hope that our discovery about the antihistamine and acupuncture can be used in the treatment trigeminal neuralgia. This present study aims to further investigate whether antihistamine dexchlorpheniramine can facilitate the analgesic effect of acupuncture in patients with trigeminal neuralgia.

Trigeminal neuralgia (TN) is one of the most painful and common types of neuropathic pain encountered by clinicians. It is typically treated pharmacologically with anticonvulsants,but these can be ineffective, or can lose their effectiveness over time.Botulinum toxin type A (BoNT-A) is an exotoxin released by the Gram-positive, anaerobic bacillus Clostridium botulinum that causes flaccid paralysis by blocking neurotransmitter release by axonal terminals. As a contaminant, it is the cause of potentially lethal botulism poisoning; however, as a drug, it has been widely used in the treatment of dystonia, as well as for non-surgical cosmetic treatment. More recently, studies investigating the ability of BoNT-A to treat pain have been increasing. In 2012, the investigators reported the results of a randomized, double-blind, and placebo-controlled trial in which subcutaneous injection of BoNT-A at the site of pain provided long-term effective relief in TN. The investigators noted that adverse effects were mild, as well. Other studies on TN have estimated the effectiveness of BoNT-A treatment in TN to be 47-73%. However, BoNT-A treatment is still ineffective in more than 30% of patients.In this study, the investigators investigate whether different treatment methods have different efficacy and safety.

The purpose of this study is to determine whether the hyperbaric oxygen treatment reduces pain and improve the life quality in trigeminal neuralgia patients.

The primary objective is to establish the feasibility of using TMS for COFP pain management in the interim period before surgery. This will be investigated by comparing the non-intervention group's self-reported pain to those who recieved TMS at several timepoints.

This is a double blinded randomized control trial of a Surface Acoustic Wave Patch device for the treatment of Trigeminal Neuralgia. This will be a crossover study for the group that receives the sham device. Subjects will be monitored for subjective criteria of pain and quality of life, as well as objective measurement of analgesic usage.

To investigate the brain activations related to TN, using fMRI, and to evaluate changes in these activations following the application of pulsed and thermal Radiofrequency lesioning to the gasserien ganglion.

Clinical characteristics, neuroanatomical findings and efficacy of medical and surgical treatment of symptomatic trigeminal neuralgia - a systematic prospective study of 60 consecutive patients

This study is designed to investigate the effectiveness and safety of 3D-CT-guided percutaneous radiofrequency thermocoagulation for the treatment of tumor-related trigeminal neuralgia.

The nature of trigeminal neuralgia (TN) is fluctuating and patients can experience periods of complete remission of pain as well as periods with excessive pain. TN is often triggered by innocuous intra- and extraoral stimuli such as chewing. Since the first-line prophylactic drugs, i.e. carbamazepine and oxcarbazepine, are administered orally, medical treatment of TN can be problematic in periods of exacerbation. In cases of severe exacerbation, patients oftentimes become dehydrated and anorectic as eating and drinking will evoke pain. Treatment with drugs administered intravenously is needed in such situations. Phenytoin was the first drug to be used for TN but it is rarely used as long-time preventative because of frequent side-effects associated with long-term use. However, phenytoin has the advantage over other drugs, that it can be administered also intravenously as fosphenytoin (the prodrug of phenytoin). By clinical experience the efficacy is very good. However, evidence of the treatment is lacking as only case reports including a total of 5 patients described the effects and side effects with pain relief lasting two days. By providing solid observational evidence, the treatment can be considered for incorporation in local and international treatment guidelines. The aim of the study is to test the hypothesis that fosphenytoin loading reduces TN pain with at least 50 % in 80% of patients with trigeminal neuralgia experiencing exacerbation of TN pain. The study is a descriptive prospective observational pilot study with 3 months followup period.

There is a significant debate whether local infiltration techniques may be a method to treat complicated chronic pain syndromes, e.g. refractory headache. Until now there is a lack of evidence regarding efficacy of this treatment especially in long term follow up. Similarly, indication and management are under debate. Aim of this trial is to analyse pain scores during first treatment with anaesthesiological infiltration series.
