Ketamine and Neuropathic Pain

Neuropathic Pain

The primary outcome is to compare the analgesic efficacy of intravenous ketamine treatment to that of a placebo in patients with refractory neuropathic pain. The secondary outcomes are: - To compare the additive analgesic efficacy of prior administration of magnesium sulfate to that of placebo and ketamine only, on the effectiveness of intravenous ketamine treatment, - To study the evolution time of pain and analgesia after the intravenous administration of ketamine and placebo, - To study the correlation of the analgesic response to administered products respectively ketamine, ketamine and magnesium sulfate, placebo.

Amitriptyline or Pregabalin to Treat Neuropathic Pain in Incurable Cancer

CancerNeuralgia

Rationale: Often, incurable cancer patients suffer from severe symptoms as (neuropathic) pain and fatigue with polypharmaceutic interventions as a consequence. Regarding neuropathic pain in incurable cancer patients, pregabalin has been registered for neuropathic non-cancer pain, and amitriptyline is not registered for neuropathic pain, but is recommended as the drug of first choice in the Dutch handbooks of palliative care. As a consequence of an adaptation of a Dutch law (July 2007) about off-label medication prescription, off-label medication is not allowed anymore unless a standard or protocol exists. No clinical trials for this patient group have been published before. Objective: To compare efficacy, side effects and costs of a strategy with amitriptyline as drug of first choice versus a strategy with pregabalin as drug of first choice. Study design: An open label, randomised non-inferiority trial Study population: Incurable cancer patients with neuropathic pain Intervention: When a patient decides to take part in the study, he will be allocated randomly to one of the two study groups. A minimisation algorithm will be used, that balances for the cause of neuropathic pain (tumour related versus treatment related), type of treatment (ongoing chemo- or radiotherapy versus not ongoing chemo- or radiotherapy) and institution. Each drug will be prescribed in a step up procedure. Patients will be followed during 8 weeks. Main study parameters/endpoints: Neuropathic pain, as measured with the mean VAS and McGill questionnaire, strategy success, costs per strategy, side effects, quality of life and concomitant analgesic drugs. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are hardly any risks for the patients. The drugs in both arms already are usual care for the target population. If there is no or a too small effect, the drug of the other arm will be added, which strategy also is already usual care. All other medication, except for Tricyclic Antidepressants Drugs (TADs) and Anti Epileptic Drugs (AEDs), as well as radiotherapy and chemotherapy are allowed. The patient has to visit the hospital 2 times during the study period. The patient had to fill in a pain diary daily (5 min), cost diary and EQ-5D every other week (10 min), related questionnaires as HADS, McGill and EORTC-QLQ-C30 monthly (20 min).

Ketamine's Efficiency in the Treatment of Chronic Pain: Kynurenin Pathway

NeuralgiaChronic Pain1 more

The kynurenine pathway is involved in hyperalgesia. This pathway is activated by inflammation. Ketamine would interact with the kynurenine pathway and inflammation. Our working hypotheses are: the clinical effects of ketamine on neuropathic pain are greater in the presence of systemic inflammation and the mechanism of action involves an interaction on the kynurenine pathway. Study design: Interventional randomized placebo-controlled clinical trial. Main goals: To show a better clinical efficacy of ketamine in chronic pain in patients with an inflammatory component. Explore the anti-inflammatory activity of ketamine through the Kynurenine pathway.

Effect of Early Use of Oxycodone During the Acute Phase of Herpes Zoster on Preventing Postherpetic...

Herpes ZosterPost-herpetic Neuralgia

Postherpetic neuralgia (PHN) which persists more than 90 days after the resolution of the acute shingles episode is the most common complication of herpes zoster. The continued pain or paresthesia not only affects patient quality of life, but also causes physical disability, emotional distress and social isolation. Conventional treatments for PHN are only partially work in some patients or not work at all in others. Once PHN presences, it is often refractory to the treatment, therefore, it is important to prevent the occurrence of PHN. In the study, the investigators want to identift whether the additional use of oxycodone therapy to current standard treatment in acute herpes zoster patients will decrease the incidence of post-herpetic neuralgia.

Postoperative Analgesia in Patients With Microvascular Decompression

Trigeminal Neuralgia

Perioperative pain is caused by a variety of harmful factors through multiple mechanisms, therefore, reasonable postoperative analgesia should be combined with drugs or measures of different mechanism , which is called multimodal analgesia. Multimodal analgesia could minimize side effects and achieve a better analgesic effect. Commonly used strategies of multimodal analgesia are oral analgesic drug, nerve block, patient controlled analgesia and so on. This study will observe the effect of multimodal analgesia on postoperative pain in patients with microvascular decompression and record side effects. Finally, it will provide technical support for the guidance of postoperative analgesia in patients of trigeminal neuralgia.
