Patients suffering from menstrual migraine (MM) may be ideal candidates for an intermittent prophylaxis, usually termed short-term or mini-prophylaxis. It covers the whole period of vulnerability, e. g., the perimenstrual period, starting some days before the expected onset of MM attack. Theoretically MM attacks are an optimal target for drugs specifically developed for acute head pain. Unfortunately, due to their particular tendency to be longer, more intense and less responsive to analgesics, symptomatic approaches alone are not often able to completely control pain and its correlates. Many drugs have been proposed for short-term prophylaxis of MM. In this paper we analyse only non-steroidal anti-inflammatory drugs, coxibs and triptans (especially those with longer half-life, naratriptan and frovatriptan). Moreover, MM can be prevented by a variety of hormonal manipulations, including oral contraceptives, which may be administered with an extended-dosing strategy; oestrogen replacement therapy; antioestrogen agents (danazol, tamoxifen); gonadotropin-releasing hormone agonists followed by oestrogen add-back therapy. Finally, the use of some products, such as magnesium and phytoestrogens, that probably meet the requirements of those patients that appreciate a more "natural" approach, is discussed.

Menstrual migraines are particularly difficult-totreat. Few studies on the use of triptans in short-term prophylaxis of menstrually related migraine have been recently conducted, but evidences of triptans' efficacy in the specific case of pure menstrual migraine (PMM) are lacking. The aim of this study is to explore the efficacy and tolerability of naratriptan as short-term prophylaxis of pure menstrual migraine (PMM) attacks. A multi-centre, open, non comparative, pilot six-month study was conducted in women, aged 18 years or older, with regular menstrual cycles and with a history of migraine without aura exclusively associated to the perimenstrual period. After an observation period of three months, patients took for three consecutive menstrual cycles oral naratriptan 1 mg twice daily, starting two days before the expected onset of menstruation and continuing for six days. Ninety-eight women with a history of PMM were screened for study participation, and 61 entered the study. Fifty-nine comprised the intent-to-treat population. The mean number of PMM attacks decreased from 3.5+/-1.4 in the 3-month observation period to 1.6+/-1.3 in the 3-month treatment with naratriptan. The pecentage of responders (subjects who recorded a decrease-equal or more than 50%-in the mean number of attacks) was 61.4%. A tendency towards a decrease in headache severity and in the presence of associated symptoms was observed during treatment. At least one adverse event during the treatment period was reported by 19 patients (31.1%). No serious adverse events occurred. Naratriptan may be an effective and safe treatment option in the short-prophylaxis of PMM.

Many women experience headaches, including migraine, in association with their menstrual cycles. Although definitions vary, menstrual migraine generally refers to migraine without aura that occurs within several days prior to and several days after the onset of menses. Although menstrual migraine has been reported to be more difficult to treat than other types of migraines, there is no evidence from controlled clinical trials to support this assertion. Thus, the pharmacological treatment of menstrual migraine should be similar to that of other types of migraines, except with respect to the use of hormonal manipulations to treat menstrual migraine. Serotonin 5-HT(1B/1D) receptor agonists (triptans) are effective for the acute treatment of both menstrual and non-menstrual migraines. When used as acute therapy, a triptan should be administered early, when the headache is still mild in severity. Ideally, an acute therapy will provide rapid and complete pain relief with no disability. Some patients may require preventive therapy for menstrual migraine based on suboptimal response to an adequate trial of acute therapy. Patient diaries that record headache onset, relationship to the menstrual cycle and treatment response through three complete cycles will allow accurate prediction of the onset of menstrual migraine; this information is also needed to make decisions about timing of intermittent preventive therapy. The goals of intermittent preventive therapy are to reduce the frequency, duration and intensity of menstrual migraine attacks. Clinical studies show that triptans are effective when used as either acute therapy or as intermittent preventive therapy for menstrual migraine. Sumatriptan and zolmitriptan have been evaluated in prospective, randomised, controlled trials for acute treatment. Retrospective analyses and open-label studies also support the use of other triptans as acute therapy. In addition, sumatriptan, frovatriptan, naratriptan and zolmitriptan have been evaluated as intermittent preventive therapy in prospective studies. Thus, data from clinical studies indicate that triptans are effective for the treatment of menstrual migraine.

Although migraine is more common in women than men and often linked to the menstrual cycle, few studies have investigated the biological basis of hormonal influences on the trigeminovascular system. In the present study we investigated the effect of physiological levels (10(-9) m) oestrogen on female rat trigeminal ganglia in vitro. Immunocytochemical analysis demonstrated the presence of oestrogen receptor-alpha in a predominantly cytoplasmic location and in neurites. Microarray analysis demonstrated that oestrogen treatment regulates several genes with potential relevance to menstrual migraine. The genes that were upregulated included synapsin-2, endothelin receptor type B, activity and neurotransmitter-induced early gene 7 (ania-7), phosphoserine aminotransferase, MHC-1b, and ERK-1. Down-regulated genes included IL-R1, bradykinin B2 receptor, N-tropomodulin, CCL20, GABA transporter protein, fetal intestinal lactase-phlorizin hydrolase, carcinoembryonic antigen-related protein, zinc finger protein 36, epsin 1 and cysteine string protein. Protein activity assays demonstrated that exposure of the cultured neurons to oestrogen leads to activation of ERK, which has been linked to inflammatory pain. Immunocytochemistry demonstrated that activated ERK was present in neurons containing peripherin, a marker of nociceptive neurons. Several of the genes in the present study may provide potential targets for understanding the association of oestrogen with migraine and other hormone-related orofacial pain.

Epidemiological data suggest a link between migraine and the female sex hormones. Indeed, it is known that estrogen affects various brain functions, including pain perception. The prevalence of migraine is similar in boys and girls before puberty, but is 3-fold higher in postpubertal females compared with males. Migraine attacks in women are more likely to occur in the perimenstrual period and occur exclusively so in some women. The acute treatment of menstrual migraine is similar to that of non-menstrually related attacks, but the response to treatment may be less favourable. Perimenstrual prophylaxis, with NSAIDs, triptans or estradiol, is effective in decreasing attack frequency and severity. The use of oral contraceptives (OCs) may change migraine frequency and severity. Since both migraine and hormonal contraceptive use are risk factors for ischaemic stroke, the use of OCs in women who experience migraine should be made only after consideration of the benefit-risk ratio. Migraine typically, but not invariably, improves during the last two trimesters of pregnancy, and may worsen in the postpartum period. When using drugs to treat migraine during pregnancy, potential risks to the mother and fetus should be considered. The prevalence of migraine decreases with advancing age and it improves in many, but not all, women after the menopause. However, in the perimenopausal period, migraine may worsen as a result of fluctuations in estrogen levels. Reducing the estrogen dose and changing the estrogen type or the route of administration of hormone replacement therapy (HRT) from oral to transdermal may reduce headache. Migraine is not a risk factor for stroke in postmenopausal women. When considering symptomatic HRT for postmenopausal migraneurs, the usual indications and contraindications should be applied. HRT may also exacerbate migraine.

Menstrual migraine (MM) attacks are a challenge for the headache specialist, because they are particularly difficult to treat. Almotriptan is a second-generation triptan successfully used for the acute treatment of migraine. No data on the efficacy and safety of almotriptan in MM treatment have been published previously. The objective was to evaluate the efficacy and tolerability of almotriptan in the symptomatic treatment of MM attacks and to compare these parameters to those obtained with zolmitriptan, another second-generation triptan. Data from a multicentre, multinational, randomised, double-blind, parallel clinical trial, conducted at 118 centres in 9 European countries, to evaluate the efficacy and tolerability of almotriptan 12.5 mg vs. zolmitriptan 2.5 mg in the acute treatment of migraine were analysed retrospectively. Of the 1061 patients included, 902 were women and 255 of these treated a MM attack: 136 with almotriptan and 119 with zolmitriptan. No significant difference between the two treatments was found. Two hours after dosing, 67.9% of almotriptan-treated and 68.6% of zolmitriptan-treated patients had obtained pain relief; while 44.9% and 41.2%, respectively, were pain free. Recurrence rates 2-24 h after dosing were 32.8% for almotriptan and 34.7% for zolmitriptan. Adverse events in the 24 h after dosing were reported by 19.8% of those taking almotriptan and 23.1% of those taking zolmitriptan. In conclusion, almotriptan is effective and safe in the treatment of MM attacks.

The changes in hormonal milieu associated with menarche, pregnancy, lactation, and menopause are frequently accompanied by changes in the patterns and frequency of migraine. Migraine headache is more common in females and, for many women, the onset of this condition occurs at menarche. As many as 60% of women migraineurs report an association between migraine and menstruation, and evidence suggests that estrogen withdrawal may be a trigger for menstrual migraine in susceptible women. Moreover, in the majority of women, migraine frequency increases during the pill-free interval with oral contraceptive use and during the postpartum period, which are other times of decreasing estrogen levels. Migraine frequency tends to decrease during periods of increasing or stable estrogen levels. For these reasons, the numerous neuroendocrine effects elicited by estrogen have been evaluated to explain its role in migraine. Overall, estrogen appears to be a key factor in menstrual migraine, but it is likely to be only one of several factors that act in concert to trigger migraine in susceptible women. Understanding the relationship of the different hormonal milieus through the natural course of women's lives can guide diagnosis and treatment.

The incidence of migraine varies over the course of the menstrual cycle. In the general population, approximately 60% of women with migraine report an increased frequency of headache during menses. The estrogen withdrawal that occurs just prior to the onset of menses and that leads to loss of serotonergic tone is thought to be the trigger for headaches that arise at this time of the menstrual cycle. The ability of triptans, specific serotonin receptor agonists, to prevent menstrual migraine is consistent with this hypothesis. Moreover, compared with headaches that occur during other times in the cycle, menstrual migraines are more severe in most women and may be of longer duration, as well as more resistant to treatment in a subset of women.

Many women report an increased frequency of headaches around the time of menses. For some women, these headaches are more severe, of longer duration, and lead to greater disability than those occurring at other times in the menstrual cycle. A headache diary is critical to properly diagnose menstrual migraine (MM) by prospectively documenting headache days, severity of headache, and the headaches' relationship to menses. In women with diagnosed MM, acute treatment has been proven to be effective in randomized clinical trials. For those women who have predictable periods and may require preventive therapy, short-term prevention is a reasonable approach due to the predictability of MM. Although several agents (eg, naproxen sodium, magnesium, triptans) have been evaluated for prevention of MM, all but triptans have been assessed in small trials of between 20 and 35 women. Naratriptan, frovatriptan, and, most recently, zolmitriptan have been proven effective in preventing MM. Triptans are generally well tolerated, and the long-term safety of these agents is currently being evaluated. The flexibility of using acute and preventive therapy allows physicians to tailor treatment of MM and meet the needs of individual patients.

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.
