Aborting a Migraine Attack: Naproxen Sodium v Ergotamine plus Caffeine

SYNOPSIS
The tolerability and efficacy of naproxen sodium and of ergotamine tartrate plus caffeine (ergotamine) were compared in the treatment of acute migraine attacks and associated symptoms. In this multicenter, double-blind, parallel study of up to six headaches over a 3-month period, patients took naproxen sodium 825 mg, ergotamine 2 mg, or placebo at the time of the first symptom of an attack; 30 minutes later, if necessary, patients repeated naproxen sodium 275 mg, ergotamine 1 mg or placebo, as appropriate. Rescue medication was allowed 30 minutes following the second dose if needed. Active drugs provided notably better relief of head pain than did placebo; 1 hour following the first dose the difference between naproxen sodium and placebo was statistically significant. Naproxen sodium was as efficacious as ergotamine in the relief of migraine attacks and associated symptoms. Relief of vomiting, nausea, photophobia, and motor symptoms favored naproxen sodium over ergotamine; these differences were statistically significant for nausea and motor symptoms. Ergotamine-treated patients reported more complaints and had more severe and longer-lasting complaints than patients on the other two regimens. Overall tolerance ratings by both investigators and patients indicated that naproxen sodium and placebo were tolerated significantly better than ergotamine.     

Sublingual Flunarizine: a New Effective Management of the Migraine Attack. A Comparison versus Ergotamine

SYNOPSIS
Flunarizine was found to be effective in the acute treatment of isosorbide dinitrate induced migraine attacks, when given in a dosage of 10 mg sublingually.
The present study consists of two parts: in the first preliminary investigation, 7 out of 8 migraine patients who developed a typical migraine attack after isosorbide dinitrate were relieved of pain within about 10 minutes. On the basis of this result a second, randomized controlled open trial was performed, in which the acute efficacy of flunarizine was compared with ergotamine tartrate, 0.25 mg i.m., on 40 migraine patients. Flunarizine was found as effective as ergotamine (75% positive responses in the flunarizine group, 70% in the ergotamine group). The mean latency of the flunarizine effect was significantly lower than that of the ergotamine ( r < 0.001, Student's t test). Moreover sublingual flunarizine was found to be virtually devoid of side effects.     

Acute migraine attack therapy: comparison of naproxen sodium and an ergotamine tartrate compound

The efficacy of safety of naproxen sodium and ergotamine tartrate were compared for the treatment of acute migraine attack in a randomized, parallel trial with 114 participating patients. At the start of symptoms, patients took either three tablets of naproxen sodium (275 mg each) or one of an ergotamine combination (containing 2 mg ergotamine tartrate, 91.5 mg caffeine, and 50 mg cyclizine chlorhydrate). Patients were followed for three months or until six attacks were monitored, whichever came first. Both medications substantially shortened the duration of migraine attacks and reduced the severity of symptoms. When the test medications were taken within 2 h of onset of attack, naproxen sodium was statistically significantly more effective than the ergotamine combination in reducing the severity of headache pain, nausea, and lightheadedness. The ergotamine combination was associated with significantly more vomiting, need for rescue medication, and side effects than was naproxen sodium. Four patients required discontinuation of the ergotamine combination and one of naproxen sodium. Both patients and investigators rated tolerance for naproxen sodium as superior to tolerance for the ergotamine combination. Naproxen sodium seems to be an effective and safe treatment for migraine attacks.     

Tolfenamic acid, metoclopramide, caffeine and their combinations in the treatment of migraine attacks

Tolfenamic acid is a fenamate which inhibits prostaglandin (PG) biosynthesis and may act as a PG antagonist as well. Caffeine and metoclopramide are used in combination with analgesics and ergotamine in the treatment of migraine attacks, but controlled clinical studies on fixed combinations with analgesics are rare. The effects of orally given tolfenamic acid (200 mg), caffeine (100 mg), metoclopramide (10 mg), tolfenamic acid + caffeine (200 mg + 100 mg), tolfenamic acid + metoclopramide (200 mg + 10 mg) and placebo were studied in 49 migraine patients (3 men, 46 women) in a double-blind randomized cross-over study comprising 482 migraine attacks. The patients were allowed to take either one or two capsules of each preparation for an attack. Additional drugs were allowed after 3 h. Parameters characterizing the effects and side-effects of the drugs were registered. Tolfenamic acid and its combinations were found to be effective in the treatment of acute migraine, but caffeine and metoclopramide alone did not differ from placebo. Combination with metoclopramide was better than tolfenamic acid alone as judged by the smaller dose needed and the intensity of attack. Between tolfenamic acid alone and its caffeine combination there were no statistically significant differences.     

A Comparative Trial of Ergotamine Tartrate, Acetyl Salicylic Acid and a Dextropropoxyphene Compound in Acute Migraine Attacks

SYNOPSIS
The effect of a dextropropoxyphene compound (Doleron(r)) was compared with that of ergotamine tartrate and acetyl salicylic acid on 525 acute migraine attacks in a double blind study of 25 adult female patients. Ergotamine and the dextropropoxyphene compound were approximately equally effective and significantly superior to acetyl salicylic acid in preventing the attacks entirely. In the cases in which the attack was only partially prevented, the dextropropoxyphene compound was more effective than ergotamine and acetyl salicylic acid in making the attacks milder and shorter. Side effects, especially gastrointestinal symptoms and fatigue, were less common with the dextropropoxyphene compound than from either of the two drugs. Probably for this reason, the patients' overall preference was clearly in favor of the dextropropoxyphene compound. The addition of dextropropoxyphene, a centrally active analgesic, to acetyl salicylic acid, gives an antimigraine compound which has an efficacy comparable with ergotamine but with less side effects.     

Bioavailability and antimigraine efficacy of effervescent ergotamine

SYNOPSIS
In about 20% of migraine patients treatment with enterally administrated ergotamine tartrate proves unsuccessful. One of the causes for this might be a poor systemic availability of the drug from the ordinary solid tablets. The present study aimed to investigate the bioavailability and the therapeutic value of ergotamine tartrate in effervescent form.
In twenty volunteers the plasma ergotamine levels were measured by using a radioimmunoassay after oral administration of 2.0 mg ergotamine tartrate combined with 50.0 mg caffeine in effervescent form. Measurable plasma drug levels were found in 14 (70%) of the subjects and the mean maximum plasma ergotamine level of 0.45 ng/ml was achieved at 30 minutes.
In the clinical part of the study 25 migraine patients treated their migraine attacks with effervescent ergotamine. The therapeutic value of it was considered as good by 9, moderate by 11 and poor by 5 of the patients. Among 18 of them the therapeutic effect seemed to be equal to their earlier ergotamine medications. The results indicate that the plasma pharmacokinetics of ergotamine tartrate in effervescent form is similar to and possibly faster on the absorptive phase than that reported earlier after enteral administration. In patients who do not gain benefit from the usual ergotamine tablets or suppositories, effervescent ergotamine would appear to be an alternative worth consideration.     

Reduced serotonin vascular sensitivity in ergotamine abusers

The action of ergotamine on the 5-hydroxytryptamine (5-HT) venous sensitivity was studied in ergotamine abuser and non-abuser migraine patients. Ergotamine abusers showed reduced 5-HT hand vein contraction during abuse, compared to seven days after ergotamine withdrawal. In non-ergotamine users, the 5-HT venoconstriction was not significantly modified 12 h after a single intramuscular ergotamine (0.25 mg) administration. Even the administration of ergotamine locally into the vein did not change the venospasm of 5-HT given acutely in the same vein. Therefore, it seems that the 5-HT antagonism does not contribute to the therapeutic effect of ergotamine during the migraine attack. Moreover, the reduced 5-HT responsiveness during ergotamine abuse may possibly be compatible with the chronic headache present in some abusers, the withdrawal headache attacks and the abuse itself.     

Ergotamine and dihydroergotamine: a review

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.     

Treatment choices and patterns in migraine patients with and without a cardiovascular risk profile

Treatment patterns in migraine patients with cardiovascular risk factors are largely unknown. A retrospective observational study was conducted to characterize the baseline cardiovascular risk profile of new users of specific abortive migraine drugs, and to investigate treatment choices and patterns in patients with and without a known cardiovascular risk profile. New users of a triptan, ergotamine or Migrafin^® ( n  = 36 839) from 1 January 1990 to 31 December 2006 were included. Approximately 90% of all new users did not have a clinically recognized cardiovascular risk profile. The percentage of new users with a cardiovascular risk profile did not differ between new users of a triptan, ergotamine or Migrafin^® and also did not change during the study period of 17 years. Differences in treatment choices and patterns between migraine patients with and without a known cardiovascular risk profile reveal a certain reticence in prescribing vasoconstrictive antimigraine drugs to patients at cardiovascular risk.     

Medical therapy for menstrual migraine

A menstrual migraine occurs in approximately 7-10 % of women suffering from migraine. The migraine occurs from 2 days before until 3 days after the end of the menstrual period. The choice of treatment depends on the duration of the attack, which ranges from 3 to 7 days. An attack of up to 3 days duration should be treated with acetylsalicylic acid, ergotamine tartrate or naproxen, each in combination with an antiemetic (domperidone, metoclopramide). If there is no response, sumatriptan can be administered orally (25-100 mg) or subcutaneously (6 mg). In the attacks continue for more than 3 days, short-term prophylaxis with naproxen or the application of an estrogen-containing patch is indicated. Neither ovulation inhibitors nor traditional migraine prophylaxis has an influence on menstrual migraine. Patients should keep a headache diary. Short-term prophylaxis with ergotamine tartrate or tamoxifen is obsolete.     

Enhancing the Effectiveness of Abortive Therapy: A Controlled Evaluation of Self-Management Training

Research suggests that approximately one half of recurrent headache sufferers fail to adhere properly to drug treatment regimens with as many as two thirds of patients failing to make optimal use of abortive medications such as ergotamine. In spite of these findings there are no controlled studies that have attempted to evaluate methods for improving adherence to drug regimens for the treatment of chronic headache disorders. In an initial effort to address this adherence problem thirty-four recurrent migraine sufferers were randomized to abortive therapy with ergotamine tartrate plus caffeine (standard abortive therapy) or to standard abortive therapy accompanied by a brief educational intervention designed to facilitate the migraine sufferer's effective use of ergotamine. Patients who received the adjunctive educational intervention attempted to abort a greater percentage of their migraine attacks (70% vs 40%) and showed larger reduction in headache activity (e.g., 40% vs 26% reduction in month two of treatment). However, patients in both treatment groups used similar amounts of abortive medication when attempting to abort a migraine attack and showed similar reductions in analgesic medication use with abortive therapy. There results suggest that brief educational interventions designed to address the problem of patient adherence may yield significant improvements in standard therapies. We argue that such educational interventions deserve more attention in the headache treatment literature than they have received to date.     

Atenolol for Migraine Prophylaxis

SYNOPSIS
The preventive effect of atenolol on migraine attacks was compared to placebo in a double-blind cross-over study. 24 patients with classic and/or common migraine entered the 36-week study; four subsequently dropped out. The effect of atenolol was significantly better than that of placebo. The number of headache attacks was reduced in 15 of 20 patients (r<0.05) and the values for integrated headache diminished in 19 of 20 patients (r<0.001).
Intake of ergotamine products was significantly lower in all patients using such drugs, while the consumption of common analgesics did not differ between the trial periods. No serious side effects were noted.     

Dihydroergotamine nasal spray during migraine attacks

Ergot derivatives have been used in the treatment of migraine for more than 50 years. We have compared the efficacy of dihydroergotamine (DHE) nasal spray with that of placebo in patients with classic or common migraine attacks. The study was performed in accordance with a double-blind, crossover design. In this study a great placebo effect was observed with a dose of 1.36 mg/attack, and the overall efficacy was rated by the patients to be 41% and 52% for placebo and DHE, respectively.     

Long-term ergotamine abuse: effect on adrenergically induced mydriasis.

The mydriatic action of sympathomimetic eyedrops after a therapeutic dose of ergotamine was measured in migraine patients with and without histories of long-term ergotamine abuse. Mydriasis induced by the postsynaptic alpha 1-agonist phenylephrine was similar in both groups of patients tested, whereas pupillary dilation caused by the release of noradrenaline tyramine was markedly greater in patients with histories of ergotamine abuse. The enhanced response to tyramine disappeared after drug withdrawal. These findings indicate that continuous ergotamine medication causes a reversible alterations in iris sympathetic transmission. This manifestation may reflect a central inhibition of pupillary sympathetic activity.     

History of the use of ergotamine and dihydroergotamine in migraine from 1906 and onward

Dale showed in 1906 in a seminal work that ergot inhibits the pressor effect of adrenaline. Stoll at Sandoz isolated ergotamine from ergot in 1918. Based on the belief that migraine was due to increased sympathetic activity, ergotamine was first used in the acute treatment of migraine by Maier in Switzerland in 1925. In 1938 Graham and Wolff demonstrated the parallel decrease of temporal pulsations and headache after ergotamine i.v. This inspired the vascular theory of Wolff: an initial cerebral vasoconstriction followed by an extracranial vasodilation. Dihydroergotamine (DHE) was introduced as an adrenolytic agent in 1943. It is still in use parenterally and by the nasal route. Before the triptan era ergotamine and DHE had widespread use as the only specific antimigraine drugs. From 1950 the world literature on ergotamine was dominated by two adverse events: ergotamine overuse headache and the relatively rare overt ergotism. Recently, oral ergotamine, which has an oral bioavailability of < 1%, has been inferior to oral triptans in randomized clinical trials. A European Consensus in 2000 concluded that ergotamine is not a drug of first choice. In an American review of 2003 it was suggested that ergotamine may be considered in the treatment of selected patients with moderate to severe migraine.     

French guidelines for the diagnosis and management of migraine in adults and children

BACKGROUND: The French Recommendations for Clinical Practice: Diagnosis and Therapy of Migraine are guidelines concerning the overall management of patients with migraine, including diagnostic and therapeutic strategies and assessment of disability. OBJECTIVE: This article summarizes the guidelines as they apply to adults and children, and proposes future direction for steps toward optimal treatment of migraine in patients in France. METHODS: The recommendations were categorized into 3 levels of proof (A-C) according to the National Agency for Accreditation and Evaluation in Health (ANAES) methodology and were based on a professional consensus reached among members of the Working Group and the Guidelines Review Group of the ANAES. RESULTS: The International Headache Society diagnostic criteria for migraine should be used in routine clinical practice. Recommended agents for the treatment of migraine in adults include nonsteroidal anti-inflammatory drugs, acetylsalicylic acid (ASA) monotherapy or in combination with metoclopramide, acetaminophen monotherapy, triptans, ergotamine tartrate, and dihydroergotamine mesylate. Patients should use the medication as early as possible after the onset of migraine headache. For migraine prophylaxis in adults, the following can be used: propranolol, metoprolol, oxetorone, or amitriptyline as first-line treatment, and pizotifen, flunarizine, valproate sodium, or topiramate as second-line treatment. Migraine in children can be distinguished from that in adults by shorter duration (2-48 hours in children aged <15 years), more frequent bilateral localization, frequent predominant gastrointestinal disturbances, and frequent pallor hailing the onset of the attack. The following drugs are recommended in children and adolescents: ibuprofen in children aged >6 months, diclofenac in children weighing >16 kg, naproxen in children aged >6 years or weighing >25 kg, ASA alone or in combination with metoclopramide, acetaminophen alone or in combination with metoclopramide, and ergotamine tartrate in children aged >10 years. CONCLUSIONS: These guidelines are intended to help general practitioners to manage migraine patients according to the rules of evidence-based medicine.     

Divalproex sodium in migraine prophylaxis: a dose-controlled study

Objective : To evaluate the efficacy and safety of divalproex sodium (DVPX) when used as prophylactic monotherapy in patients with migraine. Design : Multicenter, double-blind, placebo-controlled, parallel group. Patients were previously untreated or had failed no more than two adequate trials of prophylactic therapy. During the 4-week (single-blind) baseline, patients received placebo and completed a headache diary. Patients with two or more migraine attacks during the baseline were randomized to receive a DVPX daily dose of 500, 1000, or 1500 mg, or to placebo. The experimental phase (EP) lasted 12 weeks, the first 4 weeks for dose escalation to randomized dose, and the remaining 8 weeks for maintenance at that dose. The primary efficacy variable was 4-week migraine attack frequency during the EP. Results : One-hundred-and-seventy-six patients (44 placebo, 132 DVPX) were randomized; 171 provided efficacy data and 137 completed the study. During the EP, after adjustment for differences in baseline migraine attack frequencies, mean reductions in the DVPX groups were 1.7 (500 mg), 2.0 (1000 mg) and 1.7 (1500 mg) migraine attacks per 4 weeks compared to a mean reduction of 0.5 migraine attacks in the placebo group ( p 0.05 vs placebo). Forty-four to 45% of DVPX-treated patients, compared to 21% of patients in the placebo group achieved 50% reduction in their migraine attack frequencies ( p 0.05 vs placebo). The recommended initial dose of DVPX in migraine prophylaxis is 500 mg per day, although some patients may benefit from higher doses. Adverse events were similar in the DVPX and placebo treatment groups except for nausea, dizziness and tremor, in which incidence rates were significantly higher in the DVPX 1500 mg group (nausea was also higher in 500 mg group) than in the placebo group. Conclusion : Divalproex sodium is an effective prophylactic treatment in migraine and is generally well tolerated.     

Comparison of pharmacodynamic effects and plasma levels of oral and rectal ergotamine

Plasma levels and the vasoconstrictive effect of 1 mg ergotamine tartrate given as tablets or suppositories were compared. In a crossover study, eight male volunteers received tablets or suppositories containing ergotamine in a drug combination (Anervan) and, as a control, suppositories without ergotamine. Blood sampling and measurement of toe-arm systolic gradients with a strain-gauge technique were done for up to 6 h and again after 24 h and 48 h. Only 29 of 160 blood samples contained detectable (greater than 0.1 ng/ml) amounts of ergotamine, and kinetic comparison could not be performed. Only ergotamine-containing suppositories caused a significant (p less than 0.008) decrease in toe-arm systolic gradient which was significantly different (p less than 0.003) from the effects of ergotamine tablets and control suppositories. Rectal ergotamine is thus more biologically active, for the factor used, than oral ergotamine. We suggest that a rectal dose of 1 mg ergotamine tartrate should be tried as the initial dose in the treatment of migraine attacks.
