Diphenhydramine and Migraine Treatment Failure in Pediatric Patients Receiving Prochlorperazine.

The objectives are to determine whether diphenhydramine coadministered with prochlorperazine versus prochlorperazine only is associated with a difference in the risk of migraine treatment failure, as measured by the need for additional therapy, hospitalization rates, and 72-hour return rates, and to compare extrapyramidal adverse effects between groups. Retrospective cohort of patients aged 7 to 18 years treated in the emergency department for migraines using prochlorperazine with or without diphenhydramine between 2013 and 2019. Patients were included if they had International Classification of Diseases, Ninth or Tenth Revision, codes for migraine or unspecified headache and were treated with prochlorperazine as part of their initial migraine therapy. Data collected included demographics, medications administered, pain scores, neuroimaging, disposition, return visits, and documentation of extrapyramidal adverse effects. Multivariable logistic regression was used to estimate the association between diphenhydramine coadministration and each of the outcomes. A total of 1683 patients were included. Overall, 13% required additional therapy with a 16.7% admission rate and a 72-hour return rate of 5.3%. There was no association between initial treatment with diphenhydramine and the odds of additional therapy (adjusted odds ratio [aOR], 0.74 [95% confidence interval {CI}, 0.53-1.03]), admission rates (aOR, 1.22 [95% CI, 0.89-1.67]), or return visit rates (aOR, 0.91 [95% CI, 0.55-1.51]). Extrapyramidal adverse effects occurred in 2.4% of patients in the prochlorperazine group and 0% in the prochlorperazine with diphenhydramine group. There was no association between diphenhydramine coadministration and the need for additional therapy, 72-hour return visit rates or admission rates. Extrapyramidal effects did not occur in patients treated with diphenhydramine.

Results of a Web-Based Survey on 2565 Greek Migraine Patients in 2023: Demographic Data, Imposed Burden and Satisfaction to Acute and Prophylactic Treatments in the Era of New Treatment Options.

Objective: The Greek Society of Migraine and Headache Patients conducted its third in-line population web-based survey in 2023 to ascertain if the burden of the disease and the patients' satisfaction with conventional and novel migraine therapies are changing compared to our previous findings from 2018 and 2020. Methods: The sampling process was based on a random call to participants to reply to a specific migraine-focused self-administered questionnaire, including 83 questions in Greek, which was distributed nationwide through the online research software SurveyMonkey. Results: We eventually enrolled 2565 patients, the majority of which were females. Our findings clearly demonstrate that migraine is still a burdensome condition. The degree of its impact on all aspects of productivity depends on the monthly frequency of migraine and the response rates to acute and prophylactic treatments. A total of 1029 (42.4%) of the patients had visited the emergency room mainly for unresponsiveness to acute treatments or aura-related symptoms. Triptans seem to be partly effective as acute therapies. OnabotulinumtoxinA seems to be effective for almost half of chronic migraine patients (43.9%) to report adequate satisfaction with this treatment (27.8% were "fairly happy", 10.6% were "very happy", and 5.5% were "extremely happy"). Due to their high rates of preventative effectiveness, most respondents treated with anti-CGRP Mabs expressed their optimism concerning their future while living with their migraine (88.25%), as well as towards further improvements in their quality of life (82.8%) status, mostly with fremanezumab. Conclusions: The patients recognize the usefulness of anti-CGRP Mabs in migraine prevention and consequently seem to be more optimistic than before about living with migraine. Considering the market change that is anticipated with the use of gepants and ditans, larger longitudinal population-based studies are warranted to further explore if the new era of migraine therapeutics might further lessen the burden of the disease.

Use of Calcitonin Gene-Related Peptide Monoclonal Antibodies for the Treatment of Migraines in Individuals With Multiple Sclerosis.

Migraines are a common comorbidity and source of disability in patients with chronic inflammatory diseases like multiple sclerosis (MS). Recently, therapeutic agents for episodic and chronic migraine known as calcitonin gene-related peptide (CGRP) inhibitors have shown to effectively control migraine attacks and improve quality of life in the general population. This study explored the use of these novel agents in individuals with comorbid MS. This was a retrospective, population-based cohort study at the University of South Florida's neurology clinic; it evaluated individuals with both MS and migraine. A total of 27 individuals with MS and chronic or episodic migraine who received treatment with a CGRP monoclonal antibody were identified. Of these, 63% reported a reduction in their migraine frequency of greater than 75%. Concurrent use of a disease-modifying therapy (DMT) for MS occurred in 82% of patients, and in 37% of these, the DMT used was also a monoclonal antibody. Adverse effects from CGRP monoclonal antibodies were mild and occurred in only 11% of patients, and no patient experienced worsening of their MS symptoms during cotreatment over the duration of the study. Our study showed a significant reduction in migraine frequency and a favorable adverse event profile for individuals with comorbid MS who took CGRP monoclonal antibodies and experienced no worsening of MS symptoms. In individuals with MS, CGRP monoclonal antibodies seem to be a safe and effective therapy for episodic or chronic migraine.

Transcranial direct current stimulation for migrane

Migraine is one of the most common primary headache disorders. Nowadays, there is an increase in the prevalence of migraine. It causes a significant reduction in the Quality of Life of those affected. There are two major approaches to treating migraines: attack management and prevention. The concept of primary prophylactic therapy of migraine has developed rapidly. In addition to standard medication, there are increasing data indicating the usefulness and feasibility of non-drug treatments, such as TES (transcranial electrical stimulation). Both cathodal and anodal stimulation have been shown to be effective in migraine treatment: after a course of TES, the number of days per month with headache decreased, the duration and intensity of migraine attacks decreased, and some studies reported a reduction in the number of medications used. O1/O2 (1–2 mA) for cathodal stimulation and F3/F4 (1–2 mA) for anodal stimulation were the most frequently stimulated cortical areas. The average duration of each session was 20 minutes. The length of TES sessions varied from study to study. TES has shown efficacy and safety in treating various forms of migraine. Using this non-invasive method to prevent attacks may be one of the directions for personalizing migraine treatment.

Application and Effectiveness of Dietary Therapies for Pediatric Migraine

Migraine is a representative type of primary headache and a common chronic neurological disease that accounts for a large proportion of headaches in children, adolescents, and adults. Unlike migraine in adulthood, pediatric migraine occurs when brain development is not yet complete. This characteristic may require a new perspective for the treatment and management of pediatric migraine. Dietary therapies, mainly the ketogenic diet and its variants, can have positive effects on pediatric migraine. Several recent studies have revealed that dietary therapies, such as the classic ketogenic diet, modified Atkins diet, and low glycemic index diet, improve various neurological diseases by improving dysbiosis of microbiota, reducing proinflammatory cytokines, and increasing mitochondrial function. Nonetheless, the mechanism through which active dietary therapy affects pediatric migraine requires further research. To achieve this, an important role is played by the neuro-nutritional team, which can develop and manage tolerable diets for pediatric migraine patients through mutual collaboration among pediatric neurologists, nurses, and nutritionists.

Long-Term Outcome After Discontinuation of CGRP-Targeting Therapy for Migraine.

Calcitonin gene-related peptide (CGRP)-targeting agents are potential candidates for disease-modifying migraine drugs. However, most studies on CGRP-targeting agents have assessed efficacy outcomes rather than long-term effects after discontinuation. This review aimed to synthesize and scrutinize the latest clinical data on the outcomes after the discontinuation of CGRP-targeting therapy in patients with episodic and chronic migraine, with a particular focus on chronic migraine. Real-world studies involving patients with migraine have reported consistent findings of worsened headache frequency and quality of life after the discontinuation of CGRP monoclonal antibodies (CGRP mAbs). Although many patients maintain improvements for up to 4months after discontinuation compared to baseline (before starting CGRP mAbs), no studies have evaluated the effects of stopping treatment for > 5months, which is the five-half-life of CGRP mAbs. Several studies have suggested that patients treated with CGRP receptor mAbs experience more rapid deterioration than those treated with CGRP ligand mAbs after discontinuing CGRP mAbs. The results of real-world studies suggest that for many patients with migraine, the benefits of CGRP mAbs diminish months after discontinuation. Therefore, anti-CGRP therapies may not be considered disease-modifying. However, the comprehensive assessment of the disease-modifying potential of these drugs requires studies with extended treatment and cessation durations.

New treatment for migraines: Use of monoclonal antibodies – Review

Migraine is one of the most prevalent diseases in the population and is also one of the main disabling diseases, having a negative impact on the sufferer's quality of life. Migraine mainly affects people of working age, reducing productivity and impacting the entire labor market. The field of migraine therapies includes monoclonal antibodies that inhibit the Calcitonin Gene Related Peptide (CGRP), which has a strong correlation with the pathophysiology of migraine attacks. Therefore, this study aims to investigate the literature to review the treatment of migraines with the use of monoclonal antibodies, analyzing the prognosis and improvement of patients who have undergone treatment. A systematic review of the literature was carried out between September 2021 and April 2022 by two independent researchers. A total of 1,105 articles were identified, of which 33 met the inclusion criteria and were then analyzed. The use of the monoclonal antibodies Erenumab, Eptinezumab, Fremanezumab and Galcanezumab showed better results in all the parameters analyzed when compared to the placebo groups. They showed a reduction in the average number of migraine days per month, a reduction in the number of days with crises, a reduction in the use of acute medication and an improvement in quality of life assessment scores. In conclusion, monoclonal antibodies are an innovative therapy for migraine and are emerging as preventive options with good tolerability in terms of adverse effects and efficacy. Further research should be carried out with a view to evaluating efficacy and long-term safety, given the recent introduction of this therapy.

Preventive Treatment of Migraine.

This article describes strategies for the preventive treatment of migraine including the emerging role of calcitonin gene-related peptide (CGRP)-targeted therapies and introduces novel paradigms for the preventive treatment of migraine. Multiple migraine medications targeting CGRP have been introduced since 2018, including injectable monoclonal antibodies (ie, eptinezumab, erenumab, fremanezumab, and galcanezumab) and oral small-molecule CGRP receptor antagonists (ie, ubrogepant, rimegepant, atogepant, and zavegepant). With the exceptions of ubrogepant and zavegepant, which are approved only as acute treatments, all of these agents have demonstrated efficacy in the preventive treatment of migraine; the monoclonal antibodies and atogepant have evidence of effectiveness in adults with either episodic or chronic migraine. The safety and tolerability profiles of CGRP-targeted therapies in migraine are favorable. The goals of preventive migraine therapy include reducing the frequency, severity, duration, and disability associated with attacks, reducing the need for acute treatment and the risk of medication overuse, enhancing self-efficacy and health-related quality of life, and reducing headache-related distress and interictal burden. Six drugs targeting CGRP (four monoclonal antibodies and two gepants) are now available for the preventive treatment of episodic migraine in adults. The efficacy of CGRP-targeted medications in the acute and preventive treatment of migraine, together with good safety and tolerability, has led to the emergence of new approaches to preventive treatment.

Restoring brain health: Electroacupuncture at GB20 and LR3 for migraine mitigation through mitochondrial restoration.

Electroacupuncture (EA) is a promising alternative therapy for migraine, with mitochondrial dysfunction hypothesized as a pivotal mechanism in migraine pathophysiology. This research endeavors to investigate the therapeutic potential of EA in addressing migraines and shed light on the associated mechanisms linked to mitochondrial anomalies. Migraine in rats was induced by 10 mg/kg nitroglycerin, followed by 2/15 Hz EA treatment at GB20 and LR3. Nociceptive behavior was recorded via a camera and analyzed using EthoVision XT 12.0 software. The hind-paw withdrawal threshold was assessed using the von Frey test. We assessed the levels of calcitonin gene-related peptide (CGRP), nitric oxide (NO), and endothelin (ET) - key parameters in migraine pathophysiology using immunohistochemistry and enzyme-linked immunosorbent assay. Mitochondrial morphology in brain tissues was observed through transmission electron microscopy. Reactive oxygen species (ROS) level in mitochondria was measured by flow cytometry. The levels of PINK1 and Parkin were assessed using Western blot analysis. EA at GB20 and LR3 decreased nociceptive behaviors (resting and grooming) and increased exploratory and locomotor behaviors in migraine rats. The hind-paw withdrawal threshold in migraine rats was significantly elevated following EA treatment. Post-EA treatment, levels of CGRP and NO decreased, while ET level increased, suggesting an alteration in pain and vascular physiology. Notably, EA treatment mitigated the mitochondrial damage and reduced ROS level in the brain tissues of migraine rats. EA treatment upregulated the expression of PINK1 and Parkin in migraine rats. EA at GB20 and LR3 may treat migraine by alleviating PINK1/Parkin-mediated mitochondrial dysfunction.

Anti-CGRP-based Migraine Medications: A Comprehensive Overview

In the early 1990s, the neuropeptide calcitonin gene-related peptide (CGRP) was identified as a key messenger in the pathophysiology of migraine and emerged as a treatment target, fundamentally transforming our approach to migraine therapy. While previous prophylactic drugs were non-specific and often caused intolerable side effects, the discovery of CGRP marked the advent of a new era in migraine treatment. The two main classes of CGRP-specific migraine treatments are monoclonal antibodies that bind to CGRP or the CGRP receptor, and CGRP receptor antagonists, the so-called gepants. Extensive clinical trials have conclusively demonstrated the safety, tolerability, and efficacy of monoclonal CGRP(-receptor) antibodies in the prophylactic treatment of both episodic and chronic migraine. The same positive results apply to the use of various gepants. They have proven to be not only an effective alternative to triptans in acute migraine therapy but also promising options for continuous use as prophylactic treatments. In this review, we aim to present the current state of research on CGRP-specific migraine therapy and insights in real-world data from the first years after their launch in clinical practice.

Structural equation modeling for identifying the drivers of health-related quality of life improvement experienced by patients with migraine receiving eptinezumab

BackgroundAs new migraine therapies emerge, it is crucial for measures to capture the complexities of health-related quality of life (HRQoL) improvement beyond improvements in monthly migraine day (MMD) reduction. Investigations into the correlations between MMD reduction, symptom management, and HRQoL are lacking, particularly those that focus on improvements in canonical symptoms and improvement in patient-identified most-bothersome symptoms (PI-MBS), in patients treated with eptinezumab. This exploratory analysis identified efficacy measures mediating the effect of eptinezumab on HRQoL improvements in patients with migraine.MethodsData from the DELIVER study of patients with 2–4 prior preventive migraine treatment failures (NCT04418765) were inputted to two structural equation models describing sources of HRQoL improvement via Migraine-Specific Quality-of-Life Questionnaire (MSQ) scores. A single latent variable was defined to represent HRQoL and describe the sources of HRQoL in DELIVER. One model included all migraine symptoms while the second model included the PI-MBS as the only migraine symptom. Mediating variables capturing different aspects of efficacy included MMDs, other canonical symptoms, and PI-MBS.ResultsIn the first model, reductions in MMDs and other canonical symptoms accounted for 35% (standardized effect size [SES] − 0.11) and 25% (SES − 0.08) of HRQoL improvement, respectively, with 41% (SES − 0.13) of improvement comprising “direct treatment effect,” i.e., unexplained by mediators. In the second model, substantial HRQoL improvement with eptinezumab (86%; SES − 0.26) is due to MMD reduction (17%; SES − 0.05) and change in PI-MBS (69%; SES − 0.21).ConclusionsImprovements in HRQoL experienced by patients treated with eptinezumab can be substantially explained by its effect on migraine frequency and PI-MBS. Therefore, in addition to MMD reduction, healthcare providers should discuss PI-MBS improvements, since this may impact HRQoL. Health technology policymakers should consider implications of these findings in economic evaluation, as they point to alternative measurement of quality-adjusted life years to capture fully treatment benefits in cost-utility analyses.Trial registration ClinicalTrials.gov (Identifier: NCT04418765; EudraCT (Identifier: 2019–004497-25; URL: https://www.clinicaltrialsregister.eu/ctr-search/search?query=2019-004497-25).Graphical

Migraine and gasdermin D: a new perspective on the inflammatory basis of migraine.

Migraine is a common and disabling primary headache disorder and inflammation is a proposed factor in the complex ethiology of the disease. Gasdermin D (GSDMD) is a membrane pore-forming protein acting through the caspase system. End result is cell death caused by leakage of intracellular components to extracellular space which also results in inflammation. Stemming from this knowledge, the potential role of GSDMD in migraine was investigated in this prospective study. This prospective study was conducted between September 2022 to April 2023. 47 patients with migraine were designated as the patient group, whereas 47 healthy volunteers were designated as the control group. Serum GSDMD levels of both groups were compared, with an additional comparison between migraine patients during symptom-free and attack periods. Migraine related characteristics of the patients were also included in the study. Median GSDMD levels of the patient and control group did not reveal a significant difference. Nausea, vomiting and severity of headache were found to be correlated with GSDMD levels in migraine patients. Patients with nausea revealed a higher GSDMD level compared to patients without nausea during both symptom-free and attack periods (p = 0.021 and p = 0.01, respectively). Nausea was correlated to higher GSDMD levels in the patient population during symptom-free period (p = 0.030). The severity of pain was positively correlated with GSDMD levels during the attack period (p < 0.001). Gasdermin family and GSDMD in particular are promising prospects for therapy in a wide spectrum of disorders. Gasdermin proteins are candidates to be the focus for future studies both related to pathogenesis and drug therapy in migraine and varying inflammatory-driven clinical pictures.

Oxidative Stress and Migraine.

The pathogenesis of migraine is not completely understood, but inflammation and oxidative stress seem to be involved, according to data from an experimental model of the disease. This narrative review summarizes data from studies on oxidative stress markers in migraine patients, case-control association studies on the possible association of candidate genes related to oxidative stress with the risk for migraine, studies showing the presence of oxidative stress in experimental models of migraine, and studies on the efficacy of antioxidant drugs in migraine therapy. Many studies have addressed the value of concentrations of prooxidant and antioxidant substances or the activity of antioxidant enzymes in different tissues (mainly in serum/plasma or in blood cells) as possible biomarkers for migraine, being thiobarbituric acid (TBA) reactive substances (TBARS) such as malonyl dialdehyde acid (MDA) and 4-hydroxynonenal, and nitric oxide (this at least during migraine attacks in patients with migraine with aura (MWA) the most reliable. In addition, the possible usefulness of antioxidant treatment is not well established, although preliminary short-term studies suggest a beneficial action of some of them such as Coenzyme Q10 and riboflavin. Both topics require further prospective, multicenter studies with a long-term follow-up period involving a large number of migraine patients and controls.

Triptan treatment is associated with a higher number of red wine-induced migraine episodes: An exploratory questionnaire-based survey.

Diet, including foods and beverages, affects migraine. Conversely, the influence of migraine therapies on dietary habits is largely unknown. This study aimed at investigating the effects of triptan intake on foods and drinks consumed by adults with migraine with and/or without aura. An exploratory questionnaire-based survey took place online between November 2022 and June 2023. Participants were recruited through advertisements shared on social media accounts (e.g., Facebook and Instagram) and seasonal newsletters of three Danish patient associations. In addition, posters and flyers in headache and pain centers at Danish hospitals and private neurological, pain, and physiotherapeutic clinics were utilized. A total of 314 adults with migraine with and/or without aura completed the survey. Among the respondents, 236 individuals (75.2%) regularly used triptans to treat their migraines. Compared with non-triptan users, individuals using triptans were characterized by significantly more foods and/or drinks triggering migraine (74.2% vs. 56.4%, p = 0.005). Alcoholic beverages and most specifically red wine were overreported as migraine triggers by triptan users (48.3% vs. 21.8%, p < 0.001). In the week preceding the survey, red wine was significantly less consumed by triptan users than non-triptan users (92.4% vs. 76.9%, p < 0.001). Patients who regularly consume triptans report red wine most frequently as a migraine trigger. Triptan users are characterized by a lower consumption of red wine than non-triptan users, suggesting that a regular triptan intake may promote an increased sensitivity to red wine-induced migraine.

Efficacy of Acupuncture-Related Therapy for Migraine: A Systematic Review and Network Meta-Analysis.

Migraine is a common neurological disorder, which resulting in significant societal and personal burdens. Acupuncture has attracted widespread attention in migraine prophylaxis and treatment in recent years. Although some studies have confirmed the effectiveness of acupuncture therapy in treating migraines, there is still a lack of comprehensive evaluation regarding the comparison between different types of migraines and various acupuncture therapies. Furthermore, certain special acupuncture methods have not received sufficient attention and research. Therefore, the objective of this study is to summarize and expand upon previous research, update existing evidence, and compare the efficacy of different acupuncture therapies for migraine. We aim to provide stronger evidence-based support for clinical practice through this study, thereby promoting wider application of acupuncture therapy in migraine treatment. A exhaustive and methodical search was conducted across the nine databases: PubMed, EMBASE, Web of Science, Scopus, the Cochrane Library, CBM, CNKI, WANFANG and VIP Data. The Visual Analog Scale (VAS) scores, migraine attack frequency, duration, days of attack and adverse effects were observation indicators. This study included 34 studies involving a total of 3365 migraineurs. The results of the study demonstrated that acupuncture therapy reduced VAS scores of migraine patients better compared to medication (MD=-1.29, 95% CI=[-1.67,-0.92]) and exhibited greater efficacy in reducing the frequency of migraine attacks (MD=-1.95, 95% CI=[-3.06,-0.85]), the duration of attacks (MD=- 3.29, 95% CI=[-4.65,-1.93]), and days of attack (MD=-1.02, 95% CI=[-1.58,-0.47]). Significant heterogeneity suggested that different acupuncture therapies had varying effects, and that the efficacy of the same therapy may also vary in different migraine types. In the context of network meta-analysis, the SUCRA of acupuncture therapies for reducing VAS scores was ranked as special acupuncture method (98.3%), acupuncture plus medicine (71.9%), and acupuncture (54.5%). Blood-letting and cupping was the most effective treatment for lowering the frequency of migraine attacks. The most effective treatment for shortening the duration of migraine was acupuncture plus medication (81.2%). When it comes to decreasing the days of migraine, acupuncture (80.3%) came out on top. 14 studies reported the occurrence of adverse effects, of which 4 studies had no adverse effects in the test group. Initial findings indicate that acupuncture-related therapy exhibits superior effectiveness in the treatment of migraine and clinical decision-making should be patient-specific.

Rizatriptan benzoate-loaded dissolving microneedle patch for management of acute migraine therapy.

In this study, dissolving microneedles (MNs) using polyvinyl alcohol (PVA) and poly (1-vinylpyrrolidone-co-vinyl acetate) (P(VP-co-VA)) as matrix materials were developed for transdermal delivery of rizatriptan benzoate (RB) for acute migraine treatment. In-vitro permeation studies were conducted to assess the feasibility of the as-fabricated dissolving MNs to release RB. Drug skin penetration were tested by Franz diffusion cells, showing an increase of the transdermal flux compared to passive diffusion due to the as-fabricated dissolving MNs having a sufficient mechanical strength to penetrate the skin and form microchannels. The pharmacological study in vivo showed that RB-loaded dissolving MNs significantly alleviated migraine-related response by up-regulating the level of 5-hydroxytryptamine (5-HT) and down-regulating the levels of calcitonin gene-related peptide (CGRP) and substance P (SP). In conclusion, the RB-loaded dissolving MNs have advantages of safety, convenience, and high efficacy over conventional administrations, laying a foundation for the transdermal drug delivery system treatment for acute migraine.

Evaluation of outcomes of calcitonin gene-related peptide (CGRP)-targeting therapies for acute and preventive migraine treatment based on patient sex.

Women show increased prevalence and severity of migraine compared to men. Whether small molecule calcitonin gene-related peptide receptor (CGRP-R) antagonists (i.e., gepants) and monoclonal antibodies targeting either the CGRP-R or the CGRP peptide might show sexually dimorphic outcomes for acute and preventive therapy has not been established. We conducted a subpopulation analysis of available published data from FDA reviews to evaluate potential sex differences in the response rates of ubrogepant, rimegepant and zavegepant for acute migraine therapy. Available data from FDA reviews of erenumab, fremanezumab, galcanezumab and eptinezumab, approved CGRP-R and CGRP monoclonal antibodies and of atogepant were examined for prevention outcomes based on patient sex. Preventive outcomes were analyzed separately for patients with episodic migraine and chronic migraine. In women, the three approved gepants produced statistically significant drug effects regardless of dose tested on the FDA mandated co-primary endpoints, the proportion of patients achieving two-hour pain-freedom and the proportion of patients free of their most bothersome symptom at two hours post-dose. In women, the average placebo-subtracted two-hour pain-freedom proportion was 9.5% (CI: 7.4 to 11.6) and the average numbers needed to treat was 11. The free from most bothersome symptom at two hours outcomes were also significant in women. The gepant drugs did not reach statistically significant effects on the two-hour pain-freedom endpoint in the men, with an average drug effect of 2.8% (CI: -2.5 to 8.2) and an average number needed to treat of 36. For freedom from most bothersome symptom at two hours post-dose endpoint, differences were not significant in male patients. The treatment effect in each of the gepant studies was always numerically greater in women than in men. In evaluation of prevention outcomes with the antibodies or atogepant using the change from the specified primary endpoint (e.g., monthly migraine days), the observed treatment effect for episodic migraine patients almost always favored drug over placebo in both women and men. For chronic migraine patients the treatment effects of antibodies were similar in men and women and always favored the drug treated group.Conclusion/Interpretation: Small molecule CGRP-R antagonists are effective in acute migraine therapy in women but available data do not demonstrate effectiveness in men. CGRP-targeting therapies are effective for migraine prevention in both male and female episodic migraine patients but possible sex differences remain uncertain. In male and female chronic migraine patients, CGRP/CGRP-R antibodies were similarly effective. The data highlight possible differential effects of CGRP targeted therapies in different patient populations and the need for increased understanding of CGRP neurobiology in men and women.

PREVALENCE OF MENSTRUAL MIGRAINE AND THE EFFICACY OF SUMATRIPTAN ADMINISTRATION

Background: Menstrual migraine is a primary headache that often attacks women of reproductive age. This type of migraine has high severity and is resistant to treatment. Therefore, an effective treatment is needed to treat this menstrual migraine. Sumatriptan has been shown to have a better effect as an acute treatment for menstrual migraine patients. Purpose: This study aims to determine the prevalence and effectiveness of sumatriptan as a therapy for menstrual migraine. Methods: This research is based on a literature review following predetermined inclusion criteria. First, a literature search was carried out adhering to the PRISMA flow in 4 databases: Pubmed, Science Direct, ProQuest, and ClinicalTrial.co. Results: Based on keywords, 267 studies were found in the literature search. However, only three studies covering 845 participants met the predetermined inclusion criteria. The average age of menstrual migraine patients in the three studies was 37 years. These three studies of sumatriptan revealed a significant effect in providing a pain-free response in menstrual migraine patients. These three studies also showed that sumatriptan 100 mg has a higher level of effectiveness in providing a pain-free response in menstrual migraine sufferers and was preferably given during mild attacks. Conclusion: These three studies indicate that typically, women who suffer from menstrual migraines are of reproductive age. Additionally, this study shows that using sumatriptan as an acute therapy significantly helps provide a pain-free response in menstrual migraine patients.
