Greater ONB does not reduce the frequency of moderate to severe migraine days in patients with episodic or chronic migraine compared to placebo.The study was registered with ClinicalTrial.gov (NCT00915473).
Objectives:The primary objective of this guideline is to assist the practitioner in choosing an appropriate acute medication for an individual with migraine, based on current evidence in the medical literature and expert consensus. It is focused on patients with episodic migraine (headache on ≤ 14 days a month). Methods: A detailed search strategy was used to find relevant meta-analyses, systematic reviews and randomized double-blind controlled trials. Recommendations were graded with the Grading of Recommendations Assessment, development and evaluation (GRAde) Working Group, using a consensus group. In addition, a general literature review and expert consensus were used for aspects of acute therapy for which randomized controlled trials are not available. Results: Twelve acute medications received a strong recommendation for use in acute migraine therapy (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, zolmitriptan, ASA, ibuprofen, naproxen sodium, diclofenac potassium, and acetaminophen). Four received a weak recommendation for use (dihydroergotamine, ergotamine, codeine-containing combination analgesics, and tramadol-containing combination analgesics). Three of these were nOT recommended for routine use (ergotamine, and codeine-and tramadol-containing medications). Strong recommendations were made to avoid use of butorphanol and butalbital-containing medications. Metoclopramide and domperidone were strongly recommended for use where necessary. Our analysis also resulted in the formulation of eight general acute migraine treatment strategies. These were grouped into: 1) two mild-moderate attack strategies, 2) two moderate-severe attack or nSAId failure strategies, 3) three refractory migraine strategies, and 4) a vasoconstrictor unresponsive-contraindicated strategy. Additional strategies were developed for menstrual migraine, migraine during pregnancy, and migraine during lactation. Conclusion: This guideline provides evidence-based advice on acute pharmacological migraine therapy, and should be helpful to both health professionals and patients. The available medications have been organized into a series of strategies based on patient clinical features. These strategies may help practitioners make appropriate acute medication choices for patients with migraine.RÉSUMÉ: Lignes directrices de la Canadian Headache Society : médicaments pour traiter la crise aiguë de migraine. Objectifs : L'objectif principal de ces lignes directrices est d'aider le médecin à choisir une médication appropriée pour un individu qui présente des crises aiguës de migraine. Ces lignes directrices sont basées sur les données actuelles de la littérature médicale et sur un consensus expert. elles sont ciblées sur les patients qui souffrent de migraine épisodique (céphalée présente ≤ 14 jours par mois). Méthode : Une stratégie de recherche détaillée a été utilisée pour identifier les méta-analyses pertinentes, les revues systématiques et les essais contrôlés randomisés, à double insu.

We strongly recommend the use of prochlorperazine based on a high level of evidence, lysine acetylsalicylic acid, metoclopramide and sumatriptan, based on a moderate level of evidence, and ketorolac, based on a low level of evidence. We weakly recommend the use of chlorpromazine based on a moderate level of evidence, and ergotamine, dihydroergotamine, lidocaine intranasal and meperidine, based on a low level of evidence. We found evidence to recommend strongly against the use of dexamethasone, based on a moderate level of evidence, and granisetron, haloperidol and trimethobenzamide based on a low level of evidence. Based on moderate-quality evidence, we recommend weakly against the use of acetaminophen and magnesium sulfate. Based on low-quality evidence, we recommend weakly against the use of diclofenac, droperidol, lidocaine intravenous, lysine clonixinate, morphine, propofol, sodium valproate and tramadol.
Dietary triggers are commonly reported by patients with a variety of headaches, particularly those with migraines. The presence of any specific dietary trigger in migraine patients varies from 10 to 64 % depending on study population and methodology. Some foods trigger headache within an hour while others develop within 12 h post ingestion. Alcohol (especially red wine and beer), chocolate, caffeine, dairy products such as aged cheese, food preservatives with nitrates and nitrites, monosodium glutamate (MSG), and artificial sweeteners such as aspartame have all been studied as migraine triggers in the past. This review focuses the evidence linking these compounds to headache and examines the prevalence of these triggers from prior population-based studies. Recent literature surrounding headache related to fasting and weight loss as well as elimination diets based on serum food antibody testing will also be summarized to help physicians recommend low-risk, non-pharmacological adjunctive therapies for patients with debilitating headaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
