Abstract
OBJECTIVES The search for drugs that can protect the brain tissue and reduce nerve damage in acute ischemic stroke has emerged as a research hotspot. We investigated the potential protective effects and mechanisms of action of dihydroergotamine against ischemic stroke. METHODS C57BL/6 mice were subjected to middle cerebral artery occlusion (MCAO), and dihydroergotamine at a dose of 10 mg/kg/day was intraperitoneally injected for 14 days. Adhesive removal and beam walking tests were conducted 1, 3, 5, 7, 10, and 14 days after MCAO surgery. Thereafter, the mechanism by which dihydroergotamine regulates microglia/macrophage polarization and inflammation and imparts ischemic stroke protection was studied using enzyme-linked immunosorbent assay, immunofluorescence staining, and western blotting. RESULTS From the perspective of a drug repurposing strategy, dihydroergotamine was found to inhibit oxygen-glucose deprivation damage to neurons, significantly improve cell survival rate, and likely exert a protective effect on ischemic brain injury. Dihydroergotamine significantly improved neural function scores and survival rates and reduced brain injury severity in mice. Furthermore, dihydroergotamine manifests its protective effect on ischemic brain injury by reducing the expression of TNF-α and IL-1β in mouse ischemic brain tissue, inhibiting the polarization of microglia/macrophage toward the M1 phenotype and promoting polarization toward the M2 phenotype. CONCLUSION This study is the first to demonstrate the protective effect of dihydroergotamine, a first-line treatment for migraine, against ischemic nerve injury in vitro and in vivo.

Abstract
The advent of the triptans revolutionized acute migraine treatment. The older migraine-specific drugs, the ergot alkaloids (ergotamine and dihydroergotamine), also relieve migraine attacks through agonism at the 5-HT1B and 5-HT1D receptors, but the triptans have much greater specificity for these receptors. Unlike the ergot alkaloids, the triptans do not activate many other receptor types, and therefore are much better tolerated. This reduction in side effects greatly enhanced their clinical utility as it allowed a far greater proportion of patients to take a full therapeutic dose. As a result, the clinical use of ergotamine is minimal today, although dihydroergotamine still has a significant clinical role. There is extensive evidence that the seven triptans available today, sumatriptan, zolmitriptan, rizatriptan, eletriptan, naratriptan, almotriptan, and frovatriptan, are effective in the acute treatment of migraine. Available formulations include oral tablets, orally dissolving tablets, subcutaneous injections, nasal sprays, and in some countries, rectal suppositories. For optimal benefit, therapy needs to be individualized for a given patient both regarding the triptan chosen and the formulation. This chapter discusses the ergot alkaloids and the triptans, including mechanism of action, evidence for efficacy, clinical use, and adverse effects.

Abstract
OBJECTIVE To assess the effectiveness and adverse effects of acute cluster headache medications in a large international sample, including recommended treatments such as oxygen, commonly used medications such as opioids, and emerging medications such as intranasal ketamine. Particular focus is paid to a large subset of respondents 65 years of age or older. BACKGROUND Large international surveys of cluster headache are rare, as are examinations of treatments and side effects in older cluster headache patients. This article presents data from the Cluster Headache Questionnaire, with respondents from over 50 countries and with the vast majority from the United States, the United Kingdom, and Canada. METHODS This internet-based survey included questions on cluster headache diagnostic criteria, which were used as part of the inclusion/exclusion criteria for the study, as well as effectiveness of medications, physical and medical complications, psychological and emotional complications, mood scores, and difficulty obtaining medications. The diagnostic questions were also used to create a separate group of respondents with probable cluster headache. Limitations to the methods include the use of nonvalidated questions, the lack of a formal clinical diagnosis of cluster headache, and the grouping of some medications (eg, all triptans as opposed to sumatriptan subcutaneous alone). RESULTS A total of 3251 subjects participated in the questionnaire, and 2193 respondents met criteria for this study (1604 cluster headache and 589 probable cluster headache). Of the respondents with cluster headache, 68.8% (1104/1604) were male and 78.0% (1245/1596) had episodic cluster headache. Over half of respondents reported complete or very effective treatment for triptans (54%, 639/1139) and oxygen (54%, 582/1082). Between 14 and 25% of respondents reported complete or very effective treatment for ergot derivatives (dihydroergotamine 25%, 42/170; cafergot/ergotamine 17%, 50/303), caffeine and energy drinks (17%, 7/41), and intranasal ketamine (14%, 5/37). Less than 10% reported complete or very effective treatment for opioids (6%, 30/541), intranasal capsaicin (5%, 7/151), and intranasal lidocaine (2%, 5/241). Adverse events were especially low for oxygen (no or minimal physical and medical complications 99%, 1077/1093; no or minimal psychological and emotional complications 97%, 1065/1093), intranasal lidocaine (no or minimal physical and medical complications 97%, 248/257; no or minimal psychological and emotional complications 98%, 251/257), intranasal ketamine (no or minimal physical and medical complications 95%, 38/40; no or minimal psychological and emotional complications 98%, 39/40), intranasal capsaicin (no or minimal physical and medical complications 91%, 145/159; no or minimal psychological and emotional complications 94%, 150/159), and caffeine and energy drinks (no or minimal physical and medical complications 89%, 39/44; no or minimal psychological and emotional complications 91%, 40/44). This is in comparison to ergotamine/cafergot (no or minimal physical and medical complications 83%, 273/327; no or minimal psychological and emotional complications 89%, 290/327), dihydroergotamine (no or minimal physical and medical complications 81%, 143/176; no or minimal psychological and emotional complications 91%, 160/176), opioids (no or minimal physical and medical complications 76%, 416/549; no or minimal psychological and emotional complications 77%, 423/549), or triptans (no or minimal physical and medical complications 73%, 883/1218; no or minimal psychological and emotional complications 85%, 1032/1218). A total of 139 of 1604 cluster headache respondents (8.7%) were age 65 and older and reported similar effectiveness and adverse events to the general population. The 589 respondents with probable cluster headache reported similar medication effectiveness to respondents with a full diagnosis of cluster headache. CONCLUSIONS Oxygen is reported by survey respondents to be a highly effective treatment with few complications in cluster headache in a large international sample, including those 65 years or over. Triptans are also very effective with some side effects, and newer medications deserve additional study. Patients with probable cluster headache may respond similarly to acute medications as patients with a full diagnosis of cluster headache.

Abstract
PURPOSE OF REVIEW This article provides a systematic, evidence-based approach to acute medication choices for the patient with migraine. RECENT FINDINGS Recent clinical trials, meta-analyses, and practice guidelines have confirmed that four nonsteroidal anti-inflammatory drugs (NSAIDs) with randomized controlled trial evidence for efficacy in migraine (ibuprofen, naproxen sodium, diclofenac potassium, and acetylsalicylic acid) and seven triptans (sumatriptan, rizatriptan, eletriptan, zolmitriptan, almotriptan, frovatriptan, and naratriptan) are appropriate medications for acute migraine treatment. Dihydroergotamine (DHE) is also suitable for selected patients. SUMMARY NSAIDs and triptans are the mainstays of acute migraine therapy, and antiemetic drugs can be added as necessary. Opioids and combination analgesics containing opioids should not be used routinely. Patient-specific clinical features should help guide the selection of an acute medication for an individual patient. Acute medications can be organized into four treatment strategies for use in various clinical settings. The acetaminophen-NSAID strategy is suitable for patients with attacks of mild to moderate severity. The triptan strategy is suitable for patients with severe attacks and for those with attacks of moderate severity who do not respond well to NSAIDs. The refractory migraine strategies may be useful for patients who do not respond well to the NSAIDs or triptans alone and include using triptans and NSAIDs simultaneously in combination, DHE, and rescue medications (eg, dopamine antagonists, combination analgesics, and corticosteroids) when the patient's usual medications fail. Strategies for patients with contraindications to vasoconstricting drugs include use of NSAIDs, combination analgesics, and dopamine antagonists.Acetaminophen is the safest acute migraine drug during pregnancy, and acetaminophen with codeine is also an option. Sumatriptan may be an option during pregnancy for selected patients and is compatible with breast-feeding.

Abstract
BACKGROUND Numerous medications are available for the acute treatment of migraine in adults, and some have now been approved for use in children and adolescents in the ambulatory setting. A systematic review of acute treatment of migraine medication trials in children and adolescents will help clinicians make evidence-informed management choices. OBJECTIVES To assess the effects of pharmacological interventions by any route of administration versus placebo for migraine in children and adolescents 17 years of age or less. For the purposes of this review, children were defined as under 12 years of age and adolescents 12 to 17 years of age. SEARCH METHODS We searched seven bibliographic databases and four clinical trial registers as well as gray literature for studies through February 2016. SELECTION CRITERIA We included prospective randomized controlled clinical trials of children and adolescents with migraine, comparing acute symptom relieving migraine medications with placebo in the ambulatory setting. DATA COLLECTION AND ANALYSIS Two reviewers screened titles and abstracts and reviewed the full text of potentially eligible studies. Two independent reviewers extracted data for studies meeting inclusion criteria. We calculated the risk ratios (RRs) and number needed to treat for an additional beneficial outcome (NNTB) for dichotomous data. We calculated the risk difference (RD) and number needed to treat for an additional harmful outcome (NNTH) for proportions of adverse events. The percentage of pain-free patients at two hours was the primary efficacy outcome measure. We used adverse events to evaluate safety and tolerability. Secondary outcome measures included headache relief, use of rescue medication, headache recurrence, presence of nausea, and presence of vomiting. We assessed the evidence using GRADE (Grading of Recommendations Assessment, Development and Evaluation) and created 'Summary of findings' tables. MAIN RESULTS We identified a total of 27 randomized controlled trials (RCTs) of migraine symptom-relieving medications, in which 9158 children and adolescents were enrolled and 7630 (range of mean age between 8.2 and 14.7 years) received medication. Twenty-four studies focused on drugs in the triptan class, including almotriptan, eletriptan, naratriptan, rizatriptan, sumatriptan, sumatriptan + naproxen sodium, and zolmitriptan. Other medications studied included paracetamol (acetaminophen), ibuprofen, and dihydroergotamine (DHE). More than half of the studies evaluated sumatriptan. All but one study reported adverse event data. Most studies presented a low or unclear risk of bias, and the overall quality of evidence, according to GRADE criteria, was low to moderate, downgraded mostly due to imprecision and inconsistency. Ibuprofen was more effective than placebo for producing pain freedom at two hours in two small studies that included 162 children (RR 1.87, 95% confidence interval (CI) 1.15 to 3.04) with low quality evidence (due to imprecision). Paracetamol was not superior to placebo in one small study of 80 children. Triptans as a class of medication were superior to placebo in producing pain freedom in 3 studies involving 273 children (RR 1.67, 95% CI 1.06 to 2.62, NNTB 13) (moderate quality evidence) and 21 studies involving 7026 adolescents (RR 1.32, 95% CI 1.19 to 1.47, NNTB 6) (moderate quality evidence). There was no significant difference in the effect sizes between studies involving children versus adolescents. Triptans were associated with an increased risk of minor (non-serious) adverse events in adolescents (RD 0.13, 95% CI 0.08 to 0.18, NNTH 8), but studies did not report any serious adverse events. The risk of minor adverse events was not significant in children (RD 0.06, 95% CI - 0.04 to 0.17, NNTH 17). Sumatriptan plus naproxen sodium was superior to placebo in one study involving 490 adolescents (RR 3.25, 95% CI 1.78 to 5.94, NNTB 6) (moderate quality evidence). Oral dihydroergotamine was not superior to placebo in one small study involving 13 children. AUTHORS' CONCLUSIONS Low quality evidence from two small trials shows that ibuprofen appears to improve pain freedom for the acute treatment of children with migraine. We have only limited information on adverse events associated with ibuprofen in the trials included in this review. Triptans as a class are also effective at providing pain freedom in children and adolescents but are associated with higher rates of minor adverse events. Sumatriptan plus naproxen sodium is also effective in treating adolescents with migraine.

Abstract
Migraine constitutes a relatively common reason for pediatric emergency room visits. Given the paucity of randomized trials involving pediatric migraineurs in the emergency department setting compared with adults, recommendations for managing these children are largely extrapolated from adult migraine emergency room studies and trials involving outpatient home pediatric migraine therapy. We review current knowledge about pediatric migraineurs presenting at the emergency room and their management, and summarize the best evidence available to guide clinical decision-making.

Abstract
Migraineurs often do not use acute migraine-specific medications. Patient-reported satisfaction with triptans is modest. Patients are generally interested in obtaining more rapid and complete symptom relief. The role of trigeminal vascular activation may explain why some patients fail to respond to current treatment. Novel formulations of currently available acute migraine treatments have been developed, with improved clinical outcomes, response times, and pain-free rates. Currently available effective, novel, acute migraine therapies include needle-free injectable sumatriptan and effervescent diclofenac. Orally inhaled dihydroergotamine is a new treatment modality. These novel formulations may help patients achieve desirable outcomes, including faster and more complete relief, more consistent response, and improved drug tolerability.

Abstract
The duration of postoperative ileus following abdominal surgery is quite variable, and prolonged postoperative ileus is an iatrogenic phenomenon with important influence on patient morbidity, hospital costs and length of stay in hospital. Adequate treatment for prolonged postoperative ileus is important to improve patient morbidity and clinical efficiency. Both clinical and pharmacological management strategies have improved rapidly over the last decade, and appropriate and timely management using multimodal techniques should be used for optimal care. In this review, we define postoperative ileus, describe the pathogenesis and briefly discuss clinical management before detailing potential pharmacologic management options.

Abstract
Headache continues to be a frequent cause of emergency department (ED) use, accounting for 2% of all visits. Most of these headaches prove to be benign but painful exacerbations of chronic headache disorders, such as migraine, tension-type, and cluster. The goal of ED management is to provide rapid and quick relief of benign headache, without causing undue side effects, and to recognize headaches with malignant course. Although these headaches have distinct epidemiologies and clinical phenotypes, there is overlapping response to therapy; nonsteroidals, triptans, dihydroergotamine, and the antiemetic dopamine antagonists may play a therapeutic role for each of these acute headaches. This article reviews the diagnostic criteria and management strategies for the primary headache disorders.

Abstract
Hypotension during pregnancy must be taken seriously. This complication is definitely serious enough to merit treatment. However, examinations have been lacking so far proving the advantages or possible risks of antihypotensive therapy. A short while ago the authors reported on favourable results obtained with dihydroergotamin (DHE) in hypotensive patients. It was the aim of the present study to test this finding, which had been obtained with a relatively small group of patients, by employing a large group. The evaluation was based on the statistical data from 400 hypotensive pregnant women who had delivered during the time between 1.1. 1982 and 31.8. 1983 in the obstetrical department of the Berlin-Neukölln Hospital Pregnant women were considered to be hypotensive if they had appeared for examination at least three times up to the 28th week of pregnancy with a maximum systolic blood pressure of less than or equal to 110 mmHg and diastolic pressure of less than or equal to 60 mm Hg. In relation to the total number of births of 4763, the proportion of hypotensives was 8.4%. 204 (4.3%) hypotensive women were subjected to DHE treatment; 156 of these took regularly 2 X 2.5 mg DETMS retard, whereas compliance was irregular with the remaining 50 patients. 196 (4.1%) refused treatment. The fact that the percentage of women willing to undergo treatment was relatively low (39%) is attributed partly to pregnant women being afraid of taking drugs, and partly to the attitude adopted by gynaecologists who are often hardly convinced that hypotension is a grave sign.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Despite a large array of currently marketed, frequently effective drugs for the acute treatment of migraine headache, comprising various classes and formulations, predictably reliable treatment for most headache types is often lacking. Dihydroergotamine mesylate (DHE) is a comparatively safe and effective therapy for migraine headache that could potentially be used for a broader range of headache types than occurs at present. The features of DHE supporting this assertion include (1) effectiveness in terminating severe, long-lasting headaches, (2) rapid onset of action, (3) very low rates of headache recurrence, (4) minimal risk of medication-overuse headache, and (5) in the nasal spray formulation, suitability for outpatients (especially patients who are very nauseated or vomiting, potentially obviating the need for an office or hospital visit for acute care). Conditions or circumstances for which there are data supporting the expanded use of DHE include menstrual migraine, migraine with central sensitization and cutaneous allodynia, medication-overuse headache, migraine recurrence, and status migrainosus. The introduction of the intranasal formulation of DHE provides both pharmacologic and patient-convenience advantages for use in migraine therapy. This article reviews the rationale for the use of DHE in these common, often difficult-to-treat migraine forms.

Abstract
Migraine headaches can be frequent and disabling. Effective acute treatment can improve the quality of life for migraineurs. The migraine attack is made up of phases, which include the prodrome, aura and the headache itself. Not every migraineur experiences each phase. Each phase, however, has its own distinct pathogenesis and its own unique acute therapy. This review article will help to define the treatment strategies for the various phases of the migraine attack. It will discuss some general principles of acute migraine treatment, specific acute medications and some unique clinical situations (treatment of the prolonged aura and treating when pain is mild versus moderate/severe). It should be very apparent that a better understating of migraine pathogenesis has led to improved and more effective acute therapies for migraine.

Abstract
The clinical science of migraine headache continues to evolve. Theories of the pathophysiology of migraine have progressed from the early vascular basis of migraine to more complex current theories that emphasize the centrality of neuronal dysfunction. The most recently articulated theory of migraine is the central sensitization hypothesis, which proposes that altered processing of sensory input in the brainstem, principally the trigeminal nucleus caudalis, could account for many of the temporal and symptomatic features of migraine, as well as its poor response to triptan therapy when such treatment is initiated hours after the onset of pain. Both preclinical and clinical data support the central sensitization theory. A critical clinical implication of this theory is that drugs that are capable of either aborting or arresting the process of central sensitization, most prominently dihydroergotamine, may have a unique role in the treatment of migraine. An additional, and highly practical, implication is based upon the finding that cutaneous allodynia-pain arising from innocuous stimulation of the skin, as in hair brushing or the application of cosmetics-is an easily identifiable marker of central sensitization. Thus, the presence or absence of cutaneous allodynia can be integrated into the routine clinical assessment of migraine and utilized as a determinant of treatment. Future basic and clinical research on central sensitization is likely to be of ongoing importance to the field.

Abstract
OBJECTIVE To evaluate the safety and efficacy of a repetitive intranasal (IN) dihydroergotamine (DHE) burst protocol for treatment of refractory headaches. RESEARCH DESIGN AND METHODS Patients with refractory headaches were enrolled in a prospective, open-label, pilot study. Patients were instructed to self-administer IN DHE every 8 hours for 3 days; each IN DHE dose consisted of one 0.5-mg spray in each nostril that was repeated 15 minutes later, for a total of 2.0 mg DHE per dose. Follow-up visits were scheduled approximately 3 weeks later. MAIN OUTCOME MEASURES Efficacy and safety measurements were collected during patient interviews. Primary efficacy measures were the change in headache frequency, duration, and severity (rated from 0 [none] to 5 [extremely severe]) between the initial and follow-up visits. Safety was assessed at the follow-up visits through the occurrence of adverse events (AEs). RESULTS Twenty-six patients were enrolled in the study. Follow-up visits were completed by 24 patients whose mean headache frequency at study entry was 6.6 d/wk. The IN DHE burst protocol was associated with significant mean decreases in headache frequency (2.6 d/wk, p < 0.001), duration (5.8 hours, p = 0.03), and severity (1.2 units, p < 0.001) between study entry and the follow-up visit. One patient discontinued IN DHE use early because of an AE (nasal stuffiness); two additional patients each reported one AE (fatigue and increased headache) that was attributed to IN DHE. CONCLUSIONS The results of this pilot study suggest that the IN DHE burst protocol may be an effective and safe treatment for refractory headaches; interpretation of these results is limited by the open-label, uncontrolled design and the small number of patients. The development of a double-blind, placebo-controlled study to further evaluate this treatment regimen is warranted.

Abstract
The crustacean nervous system is an important source of substances with diverse biological activities, particularly affecting invertebrate cardiocirculatory physiology. However, the effects of these substances on the cardiovascular system of higher vertebrates are not very well documented. The purpose of this study was to evaluate the effects of a cardioexcitatory substance (CES) isolated from the eyestalk of the shrimp Peneaus vanameii on rat cardiovascular function. The administration of a purified fraction of this substance raised mean arterial pressure by 37.33 +/- 5.00 mm Hg, pulse pressure 35.00 +/- 4.93 mm Hg and heart rate 80.00 +/- 12.83 beats/min over basal values (p < 0.01). Evaluation of the possible underlying mechanisms of this hypertensive and tachycardic effect reveled that dihydroergotamine pretreatment (20 microg/0.2 mL) reduced the effect of CES on mean blood pressure, but not on heart rate. Propranolol pretreatment (4 microg/0.2 mL) reduced the tachycardia, but not the hypertensive response. Enalapril pretreatment (5 microg/0.2 mL) did not modify the effects induced by CES on heart rate or blood pressure, and the verapamil pretreatment (1 microg/0.2 mL) reduced both cardiovascular changes by 85% (p < 0.01). These results indicate that CES isolated from the shrimp eyestalk produces hypertension and tachycardia mediated by adrenergic receptors in association to calcium channels activation.

Abstract
Migraine is a chronic disorder that can be debilitating, especially when the attacks are severe and frequent. Children and adolescents are significantly affected. The prevalence of migraine in this age group is higher than predicted due to more recognition of the disease in this population throughout the past century. Severe chronic migraine can cause failure in academic work and may lead to depression. Multiple medications are used to break an acute attack. Most approaches are based on outpatient treatments and include the use of over-the-counter medications and triptans and narcotics. This manuscript reviews most of the available therapies for acute treatment of primary headache that did not respond to outpatient management.

Abstract
OBJECTIVE Treatment of pediatric migraine includes an individually tailored regimen of both nonpharmacologic and pharmacologic measures. The mainstay of symptomatic treatment in children with migraine is intermittent oral or suppository analgesics, but there is no coherent body of evidence on symptomatic treatment of childhood migraine available. The objective of this review is to describe and assess the evidence from randomized and clinical controlled trials concerning the efficacy and tolerability of symptomatic treatment of migraine in children. DESIGN Systematic review according to the standards of the Cochrane Collaboration. METHODS Databases were searched from inception to June 2004. Additional reference checking was performed. Two authors independently selected randomized and controlled trials evaluating the effects of symptomatic treatment in children (<18 years old) with migraine, using headache (HA) clinical improvement as an outcome measure. Two authors assessed trial quality independently by using the Delphi list, and data were extracted from the original reports by using standardized forms. Quantitative and qualitative analysis was conducted according to type of intervention. RESULTS A total of 10 trials were included in this review, of which 6 studies were considered to be of high quality. The number of included participants in each trial ranged from 14 to 653, with a total of 1575 patients included in this review. Mean dropout rate was 19.8% (range: 0-39.1%), and the mean age of participants was 11.7 +/- 2.2 years (range: 4-18 years). All studies used HA diaries to assess outcomes. In most studies, a measure of clinical improvement was calculated by using these diaries. Improvement often was regarded as being clinically relevant when the patients' HA declined by > or =50%. Regarding oral analgesic treatment, the effectiveness of acetaminophen, ibuprofen, and nimesulide were evaluated. When compared with placebo, acetaminophen (relative risk [RR]: 1.5; 95% confidence interval [CI]: 1.0-2.1) and ibuprofen (pooled RR: 1.5; 95% CI: 1.2-1.9) significantly reduced HAs. We conclude that there is moderate evidence that both acetaminophen and ibuprofen are more effective in reduction of symptoms 1 and 2 hours after intake than placebo with minor adverse effects. No clear differences in effect were found between acetaminophen and ibuprofen or nimesulide. Regarding the nonanalgesic interventions, nasal-spray sumatriptan, oral sumatriptan, oral rizatriptan, oral dihydroergotamine, intravenous prochlorperazine, and ketorolac were evaluated. When compared with placebo, nasal-spray sumatriptan (pooled RR: 1.4; 95% CI: 1.2-1.7) seemed to significantly reduce HAs. We conclude that there is moderate evidence that nasal-spray sumatriptan is more effective in reduction of symptoms than placebo but with significantly more adverse events. No differences in effect were found between oral triptans and placebo. All medications were well tolerated, but significantly more adverse events were reported for nasal-spray sumatriptan compared with placebo. We also conclude that there is moderate evidence that intravenous prochlorperazine is more effective than intravenous ketorolac in the reduction of symptoms 1 hour after intake. No differences in effect were found between oral dihydroergotamine and placebo. CONCLUSIONS Acetaminophen, ibuprofen, and nasal-spray sumatriptan are all effective symptomatic pharmacologic treatments for episodes of migraine in children. The new frontier for symptomatic treatment is likely to be the development of triptan agents for use in children. Most treatments have only been evaluated in 1 or 2 studies, which limits the generalizability of the findings. We strongly recommend performing a large, high-quality randomized, controlled trial evaluating different symptomatic medications compared with each other or to placebo treatment. Favorable high-quality studies should be performed and reported according to the CONSORT statement. Clinical improvement of HA should be used as the primary outcome measure, but quality of life, days missed at school, and satisfaction of child or parents should also be used as an outcome measure in future studies.

Abstract
Migraine headache can be debilitating. If initiated early, aggressive management may prevent severe disability and failure at school. It must be noted that treatments available for use for acute migraine headache in children and adolescents are off-label. Their use is widespread, but double-blind, placebo-controlled studies are still unavailable for this age group.

Abstract
STUDY OBJECTIVE Many therapies are used in the treatment of acute migraine headache, with little agreement on effectiveness. This systematic review is designed to determine the effectiveness of parenteral dihydroergotamine in reducing pain, nausea, and relapse for episodes of acute migraine in adults. METHODS Randomized controlled trials were identified using MEDLINE, EMBASE, other computerized databases, hand searching, bibliographies, and contacts with industry and authors. Studies in which dihydroergotamine (alone or in combination with an antiemetic) was compared with placebo or any other common migraine therapy were considered. Relevance, inclusion, and study quality were assessed independently by 2 reviewers. RESULTS From 281 potentially relevant abstracts, 11 studies met the inclusion criteria. Solitary dihydroergotamine use was compared to sumatriptan and phenothiazines in 3 studies; results failed to demonstrate a significant benefit of dihydroergotamine over these therapies. In 8 combination treatment studies, heterogeneity in study methodology prevented statistical pooling. However, dihydroergotamine administered with an antiemetic was as effective as or more effective than meperidine, valproate, or ketorolac across all pain, nausea, and relapse outcomes reported in all studies. CONCLUSION This evidence suggests that dihydroergotamine is not as effective as sumatriptan or phenothiazines as a single agent for treatment of acute migraine headache; however, when administered with an antiemetic, dihydroergotamine appears to be as effective as opiates, ketorolac, or valproate. Given its nonnarcotic properties, parenteral dihydroergotamine combined with an antiemetic should be considered as effective initial therapy in clinical practice.

Abstract
Migraine, according to the criteria of the International Headache Society, occurs in about 5 to 10% of children. Management of acute headache is only one of the parts of the treatment, along with identification of migraine precipitants, adjustments in lifestyle, and when necessary the use of preventive therapy, which can include non pharmacologic (relaxation or biofeedback) or pharmacologic treatment. In the acute migraine attack, a single dose of either ibuprofen 10 mg/kg or paracetamol 15 mg/kg has been shown to be effective, with only a few adverse effects. In severe migraine attacks, dihydroergotamine mesylate administered orally (20 to 40 microg/kg) or intravenously (maximum 1 mg/day) may be helpful, but there have been no large placebo-controlled trials of this treatment. Among the different triptans, it is the sumatriptan nasal spray whose efficacy has been best demonstrated. The most frequent adverse event is transitory unpleasant taste.

Abstract
This study was conducted to compare the efficacy of intravenous diphenhydramine with dihydroergotamine mesylate (DHE-45; Novartis International AG, Switzerland) in the treatment of severe, refractory, migraine headache. A retrospective review was conducted to include eighty randomly chosen patients who were admitted to the Michigan Head Pain & Neurological Institute's inpatient program at Chelsea Community Hospital. Patients had received nine doses of diphenhydramine or nine doses of DHE-45 during a 3-day period. Patients receiving DHE-45 also received metoclopramide (Reglan; AH Robins Company, Inc., Richmond, VA) as prophylaxis for nausea. Demographics, headache diagnosis, psychiatric discharge diagnoses, abortive medications, and adverse events were recorded and assessed.

Abstract
INTRODUCTION Seglor capsules, a unique modified-release formulation of dihydroergotamine mesilate, have long been in clinical use in France for migraine prophylaxis. The aim of the PROMISE (PROphylaxis of MIgraine with SEglor) study was to establish the efficacy and tolerability of Seglor in the prevention of migraine in a general practice setting. METHODS The PROMISE study was a double blind, placebo-controlled, parallel-group study carried out in primary care practice. It included 363 migraine patients treated with Seglor or placebo for 5 months after a 1-month placebo run-in phase. RESULTS Migraine attack frequency (primary efficacy criterion) decreased markedly in the two treatment groups so that the difference in favour of Seglor did not reach statistical significance. However, most secondary outcome measures (duration of single attack, total duration of attacks over 1 month, consumption of mild opiate analgesics, subjective improvement) improved to a significantly greater degree in patients receiving Seglor than in those receiving placebo. In the 84.5% of patients who had impaired quality of life at entry, the percentage of reduction in attack frequency and most other efficacy measures showed significant improvement with Seglor. The safety profile for Seglor was comparable to that of placebo. CONCLUSION These results support the effectiveness of Seglor in patients with migraine-related quality-of-life impairment. The findings of the PROMISE study also suggest that patients' quality of life should be assessed systematically before initiating a preventive treatment for migraine.

Abstract
INTRODUCTION Transient global amnesia (TGA) is defined as a selective, or almost selective, deficit of the memory that appears suddenly and lasts less than 24 hours. The aetiopathogenesis of this syndrome remains unknown and different theories have been put forward about its epileptic or ischemic origin, or the relationship that exists with the neuronal depression that is produced in migraine. A number of triggering factors have been described, including the taking of distinct pharmaceutical preparations. CASE REPORT We report the cases of two patients with a history of migraines who suffered TGA after taking ergotamine and dihydroergotamine, respectively, to treat an attack of migraine. CONCLUSIONS Given the vasoconstriction effect of these drugs, it was concluded that in both cases the main factor that triggered the TGA was the ingestion of ergots.

Abstract
OBJECTIVE To evaluate the efficacy and safety of outpatient intravenous dihydroergotamine (DHE) for treatment of refractory cluster headache. METHOD Medical records were retrospectively reviewed of all patients with cluster headache who received outpatient intravenous DHE for treatment of refractory cluster headache between January 1992 and May 2000. RESULTS One hundred four treatments were identified in 70 patients. There were 7 dropouts. Of the 97 completed treatments, 60 were for episodic cluster headache and 37 were for chronic cluster headache. Results for all treatments showed complete resolution of pain during the intravenous phase at 1 month in 61 (63%) of 97 cases, partial resolution in 13 cases (15%), and failure in 23 cases (24%). For the treatment of episodic cluster headache, there was complete resolution in 44 (73%) of 60 cases, partial resolution in 9 cases (13%), and failure in 7 cases (12%). For treatment of chronic cluster headache, there was complete resolution in 17 (46%) of the 37 cases, partial resolution in 4 cases (11%), and 16 failures (43%). As regards side effects and safety, the treatment triggered chest pain suspected of being vasospastic angina in 1 patient on day 7 of the treatment, when she was in the subcutaneous phase. Two patients dropped out due to fear of the injection, 1 because of palpitations, 1 because of chest tightness, and 2 others because of leg cramps, nausea, and diarrhea. CONCLUSIONS Outpatient intravenous DHE is a safe treatment. It is useful for refractory cluster headache, is more effective for the episodic form than the chronic form, and has a rapid onset of action. It did not change the evolution of the episodic form, but it did appear to induce remission in the chronic form or transform it to the episodic form. We advance a hypothesis to explain this.

Abstract
Chronic daily headache (CDH) is a significant public health problem with 3 to 5% of the population worldwide experiencing daily or near-daily headaches. Patients with CDH can be particularly challenging, and clinicians require a systematic approach to help guide investigations and management. The revised 2004 International Headache Society Classification Criteria introduces formalized criteria for several CDH disorders including chronic migraine and medication overuse headache as well as new daily persistent headache, hemicrania continua, hypnic headache, and SUNCT syndrome. Medication overuse is common in patients with CDH who present to physicians. Familiarity and comfort with drug-withdrawal and detoxification strategies is therefore essential. Patients with chronic migraine and chronic cluster experience significant disability and diminished quality of life. The ability to manage these patients effectively is a rewarding clinical experience.

Abstract
BACKGROUND Ensuring the appropriate use of migraine therapies is an important consideration for care providers, patients, employers, and managed care organizations (MCOs) because of the high cost of treatment for this fairly prevalent disabling disease. A review of utilization of serotonin 5-HT1 receptor agonists (triptans) in an MCO determined that about 24% of the patients who received triptan therapy exceeded the manufacturers. recommendations regarding the maximum daily dose and safe treatment guidelines in a 30-day period. An initiative was designed to manage the coverage of migraine abortive therapies with the anticipated outcome of decreasing potential misuse or overuse of the medications. OBJECTIVE The objective of this retrospective, observational study was to determine the impact of a monthly drug-specific milligram coverage maximum (quantity limit) on serotonin 5-HT1 receptor agonists (triptans) and dihydroergotamine (DHE) nasal spray on the utilization and costs of migraine care in an MCO with approximately 600000 covered members. METHODS A longitudinal, retrospective cohort analysis was conducted. All migraine-related services were analyzed, including outpatient medical visits, emergency department utilization, inpatient hospitalizations, and outpatient prescription drug use. The analysis was conducted using medical and pharmacy administrative claims. Analysis of data was performed for the period 12 months prior (October 1999 to September 2000) and 18 months postimplementation of the monthly drug-specific milligram coverage maximum (October 2000 through March 2002). RESULTS Imposition of a monthly coverage maximum for migraine-abortive therapies was associated with a 26.1% reduction in overall per- patient-per-month (PPPM) medical costs for migraine care, from US dollars 55.52 PPPM to US dollars 41.02 PPPM (P<0.01). Utilization of serotonin 5-HT1 receptor agonists and DHE nasal spray declined by 16.7%, from 0.18 prescriptions PPPM to 0.15 prescriptions PPPM (P=0.039), and direct drug costs declined by 28.8%, from US dollars 29.18 PPPM to US dollars 20.78 PPPM (P<0.001). Utilization and costs of outpatient and inpatient migraine-related medical services declined by 40% from US dollars 16.58 PPPM in the preperiod to US dollars 9.94 PPPM in the postperiod (P<0.001). CONCLUSION A monthly drug-specific milligram coverage maximum was associated with significant reduction in drug costs and utilization of serotonin 5-HT1 receptor agonists (triptans) and DHE nasal spray. Utilization and costs of migraine-related medical services also declined after implementation of the coverage maximum for triptans and DHE nasal spray. The monthly drug-specific milligram coverage maximum appeared to have been successful in managing utilization of triptans and DHE nasal spray, including reduction of overall costs of migraine-related medical services and direct drug costs.

Abstract
Ergotamine and dihydroergotamine share structural similarities with the adrenergic, dopaminergic, and serotonergic neurotransmitters. As a result, they have wide-ranging effects on the physiologic processes that they mediate. Ergotamine and dihydroergotamine are highly potent at the 5-HT1B and 5-HT1D antimigraine receptors and, as a consequence, the plasma concentrations that are necessary to produce the appropriate therapeutic and physiologic effects are very low. The broad spectrum of activity at other monoamine receptors is responsible for their side effect profile (dysphoria, nausea, emesis, unnecessary vascular effects). Both ergotamine and dihydroergotamine have sustained vasoconstrictor actions. In acute migraine treatment, their mechanisms of action involve constricting the pain-producing intracranial extracerebral blood vessels at the 5-HT1B receptors and inhibiting the trigeminal neurotransmission at the peripheral and central 5-HT1D receptors. The scientific evidence for efficacy is stronger for dihydroergotamine than for ergotamine. Their wide use is based on long-term experience.

Abstract
The ergot alkaloids were the first specific antimigraine therapy available. However, with the advent of the triptans, their use in the treatment of migraine has declined and their role has become less clear. This review discusses the pharmacology, efficacy, and safety of the ergots. In randomized clinical trials, oral ergotamine was found to be superior to placebo, but inferior to 100 mg of oral sumatriptan. In contrast, rectal ergotamine was found to have higher efficacy (73% headache relief) than rectal sumatriptan (63% headache relief). Intranasal dihydroergotamine was found to be superior to placebo, but less effective than subcutaneous and intranasal sumatriptan. Ergotamine is still widely used in some countries for the treatment of severe migraine attacks. It is generally regarded as a safe and useful drug if prescribed for infrequent use, in the correct dose, and in the absence of contraindications; however, safer and more effective options do exist in the triptans. In patients with status migrainous and patients with frequent headache recurrence, ergotamine is still probably useful.

Abstract
STUDY OBJECTIVE The practice patterns of US emergency departments in the treatment of patients with isolated benign headache have been recently described. How treatment varies among EDs has not been reported. To assess institutional variability in the pharmacotherapy of patients with benign headache, we describe and analyze the practice patterns of 3 US EDs. METHODS This health records survey included a cohort sample of consecutive adult patients aged 16 to 65 years treated with parenteral medication for isolated benign headache at 3 nonaffiliated US EDs: a large, group-model health maintenance organization, a tertiary-care academic center, and a rural community hospital. Patients who underwent a diagnostic search for intracranial pathology, who had any nonheadache secondary diagnosis, or who had coexistent trauma, fever (temperature of > or =38.0 degrees C [100.4 degrees F]), or known pregnancy were excluded from study analysis. Demographic, clinical, and pharmacotherapeutic variables were collected for each ED visit. Descriptive analyses were performed; comparisons were made with t tests. RESULTS Of the 490 eligible patients treated during the 4-month study period, the mean age was 36.4 years, and 374 (76%) were women. During their 629 visits, 364 (58%) received a migraine diagnosis, and 258 (41%) received a nonspecific headache diagnosis. Polypharmacy was common: 515 (82%) received 2 or more medications, and 154 (25%) received 3 or more medications. Pharmacotherapy varied greatly among the EDs. Use of opioid agonists showed the widest variation (16% to 72%), although use of dihydroergotamine (5% to 16%), prochlorperazine (32% to 59%), and adjunct diphenhydramine with prochlorperazine (42% versus 88%) also varied. CONCLUSION Great institutional variability exists among US EDs in the parenteral treatment of patients with isolated benign headache.

Abstract
Carotidynia is characterized by throbbing pain over the carotid artery and may be caused by migraine. We report a case of a 54-year-old woman with recurrent dysphonia associated with carotidynia and other features of atypical migraine that resolved after treatment with dihydroergotamine. To our knowledge, this is the first report of dysphonia associated with migraine.

Abstract
MT 300 is an injectable formulation of dihydroergotamine mesylate (DHE; a serotonin 5-HT1 receptor agonist) that is being developed by POZEN for the acute treatment of migraine. POZEN intends to present MT 300 as a prefilled syringe that can be administered alone, or with an autoinjector. In September 2003, POZEN announced that it had formed a commercialisation agreement with Xcel Pharmaceuticals. Under the terms of the agreement Xcel will have exclusive rights to commercialise MT 300 in the United States, and will pay POZEN upfront and milestone payments, as well as royalties on future sales. In December 2002, POZEN submitted an NDA to the US FDA for MT 300 for the acute treatment of migraine with or without aura. In March 2003 POZEN announced that its New Drug Application (NDA) for MT 300 had been accepted for filing by the US FDA. Two phase III trials have been completed in the US. Both studies, the first involving 619 patients with migraine and the second (and final study) involving 550 patients with migraine, have produced promising results. POZEN received a US patent (6,495,535) with claims related to therapeutic packaging of dyhydroergotamine in a prefilled syringe. This is the first issued patent for MT 300. POZEN has multiple pending foreign patent applications. The patents have claims regarding liquid pharmaceutical compositions for the treatment of migraine, which contain concentrated dihydroergotamine.

The antimigraine 5-HT 1B/1D receptor agonists, sumatriptan, zolmitriptan and dihydroergotamine, attenuate pain-related behaviour in a rat model of trigeminal neuropathic pain.

Abstract
1. Peripheral lesion to the trigeminal nerve may induce severe pain states. Several lines of evidence have suggested that the antimigraine effect of the triptans with 5-HT(1B/1D) receptor agonist properties may result from inhibition of nociceptive transmission in the spinal nucleus of the trigeminal nerve by these drugs. On this basis, we have assessed the potential antinociceptive effects of sumatriptan and zolmitriptan, compared to dihydroergotamine (DHE), in a rat model of trigeminal neuropathic pain. 2. Chronic constriction injury was produced by two loose ligatures of the infraorbital nerve on the right side. Responsiveness to von Frey filament stimulation of the vibrissal pad was used to evaluate allodynia. 3. Two weeks after ligatures, rats with a chronic constriction of the right infraorbital nerve displayed bilateral mechanical hyper-responsiveness to von Frey filament stimulation of the vibrissal pad with a mean threshold of 0.38+/-0.04 g on the injured side and of 0.43+/-0.04 g on the contralateral (left) side (versus > or =12.5 g on both sides in the same rats prior to nerve constriction injury). 4. Sumatriptan at a clinically relevant dose (100 microg kg(-1), s.c.) led to a significant reduction of the mechanical allodynia-like behaviour on both the injured and the contralateral sides (peak-effects 6.3+/-1.1 g and 4.4+/-0.7 g, respectively). A more pronounced effect was obtained with zolmitriptan (100 microg kg(-1), s.c.) (peak-effects: 7.4+/-0.9 g and 3.2+/-1.3 g) whereas DHE (50-100 microg kg(-1), i.v.) was less active (peak-effect approximately 1.5 g). 5. Subcutaneous pretreatment with the 5-HT(1B/1D) receptor antagonist, GR 127935 (3 mg kg(-1)), prevented the anti-allodynia-like effects of triptans and DHE. Pretreatment with the 5-HT(1A) receptor antagonist, WAY 100635 (2 mg kg(-1), s.c.), did not alter the effect of triptans but significantly enhanced that of DHE (peak effect 4.3+/-0.5 g). 6. In a rat model of peripheral neuropathic pain, which consisted of a unilateral loose constriction of the sciatic nerve, neither sumatriptan (50-300 microg kg(-1)) nor zolmitriptan (50-300 microg kg(-1)) modified the thresholds for paw withdrawal and vocalization in response to noxious mechanical stimulation. 7. These results support the rationale for exploring the clinical efficacy of brain penetrant 5-HT(1B/1D) receptor agonists as analgesics to reduce certain types of trigeminal neuropathic pain in humans.

Abstract
Combinatorial drugs utilising a clinically-proven single agent approach in erectile dysfunction (ED) have led to the search for additional compounds to improve therapy and the safety profile. Selective inhibitors of Phosphodiesterase type 5, such as Sildenafil, demonstrate a defined failure rate in ED. The therapeutic concept to increase blood influx and or to decrease blood efflux in patients with ED under therapy encountered severe drawbacks. It appeared impossible to decrease the NO-content in the corpora cavernosa and associated organs followed by synchronized increase of NO by a second drug. One has to metabolically activate cAMP by the first acting compound followed by cGMP stimulation. The pharmacology of the counteractive drugs was investigated clinically and a combination of 50 mg sildenafil with 5 mg dihydro-ergotamine (DHE) was identified as of practical use in patients with low response to Sildenafil. The safety profile appeared to be improved by this combination therapy. The present study is a clinical follow-up of patients treated with different therapeutical regimens to document the effectiveness of Sildenafil in combination with DHE.

Abstract
Migraine is a recurrent clinical syndrome characterised by combinations of neurological, gastrointestinal and autonomic manifestations. The exact pathophysiological disturbances that occur with migraine have yet to be elucidated; however, cervico-trigemino-vascular dysfunctions appear to be the primary cause. Despite advances in the understanding of the pathophysiology of migraine and new effective treatment options, migraine remains an under-diagnosed, under-treated and poorly treated health condition. Most patients will unsuccessfully attempt to treat their headaches with over-the-counter medications. Few well designed, placebo-controlled studies are available to guide physicians in medication selection. Recently published evidence-based guidelines advocate migraine-specific drugs, such as serotonin 5-HT(1B/1D) agonists (the 'triptans') and dihydroergotamine mesylate, for patients experiencing moderate to severe migraine attacks. Additional headache attack therapy options include other ergotamine derivatives, phenothiazines, nonsteroidal anti-inflammatory agents and opioids. Preventative medication therapy is indicated for patients experiencing frequent and/or refractory attacks.
