Active clinical trials for "Migraine Disorders"

Traditionally, beta blockers have been used for migraine prophylaxis, but in later years also antiepileptic drugs. Contraindications and side effects have to some degree limited their use, and new prophylactics that can be used by most migraine sufferers and with little side effects are in demand. One product that may seem to fulfill these requirements is Acetyl-L-carnitine, which is a dietary supplement and naturally occurs in plants and animals. L-carnitine is necessary for fatty-acid metabolism and energy production. To our knowledge, no placebo-controlled studies have previously evaluated the efficacy of Acetyl-L-carnitine in adults with migraine. The aims of the present study is to evaluate the efficacy of Acetyl-L-carnitine as a prophylaxis in migraine patients

Pulsed electromagnetic field (PEMF) as prophylactic treatment may prevent the attacks of migraine or decrease them even in the patients with refractory migraine.

The investigators propose to test the efficacy of ketorolac nasal spray versus sumatriptan nasal spray versus placebo for acute abortive therapy of migraine head pain as well as for migraine associated symptoms including nausea and allodynia.

The purpose of the study is to evaluate the efficacy and safety of acetaminophen and aspirin versus placebo in the acute treatment of migraine

This is a research study to assess the safety of caffeine/propranolol at different dose levels. We want to find out what effects, good and/or bad, it has on patients and their migraines.

The purpose of this study is to determine the effectiveness of melatonin 3 mg compared to placebo and amitriptyline 25 mg in the preventive treatment of migraine.

The general aim is to evaluate the relative oral bioavailability of BI 44370 TA tablets during and between migraine attacks as well as Safety, Tolerability and Pharmacokinetic

This study will provide additional efficacy data for rizatriptan when used for an acute migraine attack in patients already taking topiramate for migraine prophylaxis.

This study was designed to determine how well the combination medication, sumatriptan and naproxen sodium, treats migraine headache in adolescents 12-17 years old

Triptans are first choice drugs in the acute treatment of migraine and cluster headache. However, while in cluster headache the response rate to subcutaneous sumatriptan is 96%, around 30% of patients fail to respond to a particular triptan. Nonresponse is likely to be due to a variety of factors, including low and inconsistent absorption, inadequate dosing, and variability in individual response5. Timing of administration is also a crucial issue. In fact, an early treatment of the attack, when the pain is still mild, may increase the responders rate by circumventing the development of cutaneous allodynia (expression of central sensitization of pain pathway) during the course of the attack. Several studies have been performed in an attempt to genetically, psychologically and clinically characterize the triptan responders but failed to provide conclusive results. Nevertheless, we suggested that the presence of UAs during the migraine attack might predict a good response to triptans. UAs are common in migraine patients. They have been reported in almost one out of two migraineurs (45.8%) attending a tertiary headache centre and in more than one out of four (26.9%) in a population-based study. In an open study with sumatriptan 50 mg performed on 72 migraine patients with UAs, we described pain relief in 65.3% of the patients at 1 h and in 81.9% at 2 h, while pain-free in 30.6% at 1 h and in 61.1% at 2 h. We hypothesized a large-scale recruitment of peripheral neurovascular 5-HT1B/1D receptors consequent to the activation of the trigeminal-autonomic reflex in such patients. Our hypothesis has received further confirmation by the demonstration of higher levels of calcitonin gene-related peptide, neurokinin A and vasoactive intestinal peptide (the hallmark of the activation of the trigeminal autonomic reflex) in external jugular blood in rizatriptan responders than in non-responders. The investigators therefore postulate that migraineurs with UAs may respond better to rizatriptan than "general" migraine population. The aim of the study is to evaluate the efficacy of rizatriptan 10 mg lyophilized wafer (MLT) compared to placebo in the treatment of acute migraine in patients with unilateral autonomic symptoms (UAs: unilateral lacrimation, eye redness, eyelid oedema, nasal congestion or rhinorrhoea, miosis or ptosis, forehead or facial sweating) during the migraine attack.
