The purpose of this study is to evaluate the efficacy and effectiveness of daily dextromethorphan/quinidine (Nuedexta) in reducing the frequency and progression of episodic migraine.
The purpose of this study is to compare the rates of aspirin resistance (high residual platelet reactivity) between women with episodic and chronic migraine and women without migraine. Emerging evidence suggests that migraineurs, especially women < 45 years who have aura, have an increased risk of stroke and myocardial infarction (MI, or heart attack). The mechanism linking migraine, stroke and MI is unclear although increased platelet activation and aggregation observed during and between migraine attacks may be a plausible theory. Aspirin is an inexpensive, relatively safe antiplatelet drug that reduces the risk of stroke and MI. Preliminary data suggest that aspirin's (325mg) therapeutic effect on platelet inhibition may be reduced in migraineurs (i.e., aspirin resistance), thus limiting aspirin's effectiveness at preventing stroke and MI risks in persons with migraine. Additional research is warranted to confirm these findings in migraineurs because daily, low-dose aspirin 81 mg is the recommended first line therapy for primary and secondary prevention of stroke and MI The researchers hypothesize that resistance to aspirin 81mg may occur more frequently in women with episodic and chronic migraine than in women without migraine. The findings may have important implications for women who have migraine and use aspirin to prevent migraine symptoms or comorbidities associated with migraine including stroke and MI.
This is a pilot trial to collect data on the use of intravenous ibuprofen (IVIb) in the treatment of an acute migraine attack. Data will be collected on the efficacy of IVIb in subjects who are treated with study medication between 2 and 72 hours from time of onset of headache. Periodic safety and efficacy assessments will be performed prior to and after study drug administration. Null hypothesis: There is no difference in the proportion of subjects in the 2 treatment groups (active treatment and placebo) who have pain relief at 2 hours after the completion of the double-blind treatment infusion. Pain relief is defined as a reduction in headache pain level from severe or moderate decreased to mild or headache-free, respectively.
This is a 2 visit research study for patients with or without a diagnosis of migraine. Participants will be administered informed consent, have a medical history taken and a physical examination performed, and complete 3 questionnaires at the first visit. The participants will have a functional MRI performed after completion of Visit 1. Study stipends will be given for each completed research visit. The purpose of this study is to potentially identify risk factors and/or biomarkers (which are differences in the brain structures)by comparing the brain MRI scans of migraine sufferers to brain scans of control persons to attempt to identify migraine progression using the functional MRI scans.
Evidence-based medicine depends on distinguishing between pharmacological effects and placebo effects in randomized controlled trials (RCT). This proposal seeks to rigorously investigate fundamental questions concerning pharmacological effects, placebo effects and their interactions. Relief of symptoms of acute migraine will be the test condition for this scientific experiment because of migraine's evident clinical significance and the possibility of using participants as their own control during sequential acute migraine attacks. Our overall goal is to elucidate how the pharmacological effects of 100 mg rizatriptan (an FDA-proven effective medication for acute migraine) and the effects of placebo treatment can be modified by varied knowledge and/or expectation ("contextual") conditions. Such knowledge has the possibility to suggest potentially more efficient methodologies to test new medications that can be used to augment and enhance the apparatus of the RCT. General Aim: To elucidate and clarify what is a pharmacological effect and what is a placebo effect, how such effects vary in different knowledge/expectations contexts, and mutually constitute one another and interact. General Hypothesis: The measured pharmacological effect of an effective medication (rizatriptan) and the measured effect of placebo treatment are determined significantly by different knowledge/expectations contexts.
