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.
The objective of this trial is to assess the safety, tolerability, and efficacy of three doses of BI 44370 TA in the treatment of patients with an acute migraine attack and headache pain of moderate or severe intensity, compared to placebo and an active comparator.
This study will be the first to provide data about the relationship between PFO and migraine in children. By establishing the actual prevalence, we will better understand if PFO plays a role in the occurence of pediatric migraine and, thus, provide the incentive to perform additional studies evaluating whether PFO closure is an effective treatment option for pediatric migraine. For children with migraine headaches, discovering novel and effective treatments would be life altering.
The purpose of this study is to evaluate the safety and effectiveness of an implantable device to treat migraine. There are a significant number of patients who have drug refractory migraine and alternative therapies are needed.
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
Purpose of the study is to evaluate dose response relationship, efficacy, safety and tolerability of target doses of GSK1838262 compared to placebo in the prophylactic treatment of migraine headache. Once subjects complete the baseline and meet the randomization criteria, they will complete a 5-wk flexible titration period and then enter the 12 week maintenance period.
The purpose of this study is to see if ramelteon will reduce the number of migraine headaches over a 12 week period. The safety and tolerability of ramelteon will also be evaluated. Ramelteon has been approved by the U.S. Food and Drug Administration (FDA) for insomnia (trouble sleeping); however; ramelteon has not been approved for the prevention of migraines.
Dexamethasone is a safe and cheap abortive therapy for migraine headache. The effect of it is never evaluate and not correlate with the effect of popular anti migraine medication such as dihydroergotamine. The investigators proposal is to compare its effect with dihydroergotamine.
The purpose of this study is to determine whether topiramate effective in treating dizziness symptoms that are associated with migraine headaches.
