treatment strategies for menstrually related migraine

Approximately 50% of migrainous women suffer from menstrually related migraine (MRM), a type of migraine in which the attacks occur at the same time as or near the menstrual flow. Attacks of MRM tend to be longer, more intense and disabling and sometimes less responsive to treatment than non-menstrual migraines. Similar to the management of non-menstrual migraine, the use of triptans and NSAIDs is the gold standard for MRM treatment. In this paper, the most important studies in the literature that report the effectiveness of triptans, of certain associated drugs and other analgesic agents are summarized. Preventive strategies that can be used if a prophylactic treatment is needed is also analyzed, with particular attention paid to the use of perimenstrual prophylaxis with triptans and/or NSAIDs. Moreover, considering the peculiar interaction between menstrual migraine and female sex hormones, brief mention is made to possible hormonal manipulations

Efficacy of frovatriptan in the acute treatment of menstrually related migraine: analysis of a double-blind, randomized, multicenter, Italian, comparative study versus zolmitriptan

Menstrually related migraine (MRM) is a particularly difficult-to-treat pain condition, associated with substantial disability. Aim of this study was to compare the efficacy and safety of frovatriptan and zolmitriptan in the treatment of MRM attacks, analyzing data from a multicenter, randomized, double blind, cross-over study. We analyzed the subset of 76 regularly menstruating women who participated in one head-to-head multicenter, randomized, double blind, cross-over clinical trial and who took the study drugs to treat MRM attacks. In a randomized sequence, each patient received frovatriptan 2.5 mg or zolmitriptan 2.5 mg: after treating three episodes of migraine in no more than 3 months with the first treatment, the patient had to switch to the other treatment. MRM was defined according to the criteria listed in the Appendix of the last Classification of Headache disorders of the International Headache Society. A total of 73 attacks, classified as MRM, were treated with frovatriptan and 65 with zolmitriptan. Rate of pain relief at 2 h was 52% for frovatriptan and 53% for zolmitriptan (p = NS), while rate of pain free at 2 h was 22 and 26% (p = NS), respectively. At 24 h, 74 and 83% of frovatriptan-treated and 69 and 82% of zolmitriptan-treated patients were pain free and had pain relief, respectively (p = NS). Recurrence at 24 h was significantly (p < 0.05) lower with frovatriptan (15 vs. 22% zolmitriptan). Frovatriptan proved to be effective in the immediate treatment of MRM attacks, similarly to zolmitriptan, but showed lower recurrence rates, and thus a better sustained relief

Evolution of migraine-associated symptoms in menstrually related migraine following symptomatic treatment with almotriptan

In addition to headache, migraine is characterized by a series of symptoms that negatively affects the quality of life of patients. Generally, these are represented by nausea, vomiting, photophobia, phonophobia and osmophobia, with a cumulative percentage of the onset in about 90% of the patients. From this point of view, menstrually related migraine—a particularly difficult-to-treat form of primary headache—is no different from other forms of migraine. Symptomatic treatment should therefore be evaluated not only in terms of headache relief, but also by considering its effect on these migraine-associated symptoms (MAS). Starting from the data collected in a recently completed multicentre, randomized, double-blind, placebo-controlled, cross-over study with almotriptan in menstrually related migraine, an analysis of the effect of this drug on the evolution of MAS was performed. Data suggest that almotriptan shows excellent efficacy on MAS in comparison to the placebo, with a significant reduction in the percentages of suffering patients over a 2-h period of time

Acupressure in the control of migraine-associated nausea

Migraine is a disabling neurological disorder, aggravated by accompanying symptomatology, such as nausea. One of the most interesting approaches to nausea adopted by traditional Chinese medicine is the stimulation of the acupoint PC6 Neiguan. Actually there are no studies in medical literature as to the efficacy of treating PC6 acupoint for gastrointestinal symptoms in migraine attacks. Our study aimed at verifying if pressure applied to the acupoint PC6 was effective on nausea during migraine. Forty female patients suffering from migraine without aura were enrolled, if nausea was always present as accompanying symptomatology of their migraine. The patients were treated randomly for a total of six migraine attacks: three with the application of a device, the Sea-Band® wristband, which applies continual pressure to the PC6 acupoint (phase SB), and three without it (phase C). The intensities of nausea at the onset, at 30, 60, 120 and 240 min were evaluated on a scale from 0 to 10. The values were always significantly lower in phase SB than in phase C. Also the number of patients who reported at least a 50 % reduction in the nausea score was significantly higher in phase SB than in phase C at 30, 60 and 120 min. Moreover, the consistency of the treatment (response in at least two out of three treated attacks) was reached in 28 % patients at 60 min; in 40 % at 120 min and 59 % at 240 min. Our results encourage the application of PC6 acupressure for the treatment of migraine-associated nausea

Almotriptan 12.5 mg in menstrually related migraine: A randomized, double-blind, placebo-controlled study

Background: Menstrually related migraine (MRM) affects more than half of female migraineurs. Because such migraines are often predictable, they provide a suitable target for treatment in the mild pain phase. The present study was designed to provide prospective data on the efficacy of almotriptan for treatment of MRM

Acupuncture for pain and pain-related disability in deep infiltrating endometriosis

ObjectivesTo evaluate the efficacy of acupuncture in relieving symptoms (dysmenorrhea, dyspareunia, pelvic pain and dyschezia) intensity, improving functional disability, reducing the number of days per months of dysmenorrhea, the frequency and the efficacy of analgesic use in deep infiltrating endometriosis (DIE). The safety profile was also evaluated.MethodsThe study sample was 34 patients with DIE; for 2 months (T-2, T-1) the women recorded diary notes on the numbers of days of menstruation, the presence, intensity, and disability related to dysmenorrhea, dyspareunia, pelvic pain, and dyschezia. They then received a total of 15 acupuncture treatments over 6 months (T1–T6; once a week for 12 weeks, then once a month for 3 months).ResultsDysmenorrhea intensity was decreased during treatment. A decrease of at least 50% in number of days of dysmenorrhea, and a decrease in moderate-to-severe disability starting from T1 to T6 was recorded for 58.6% of patients. Dyspareunia intensity steadily decreased starting at T2; the percentage of women with moderate-to-severe disability declined from 73.3% at T-2, to 36.9% at T3, T4, and T5. A decrease in pelvic pain score was noted starting at T1; the percentage of disability decreased from 83.3% at T-2 to 33.3% at T3 and T6. The intensity of dyschezia decreased from T-2 to T3 and T4 and then increased slightly. Analgesic drug use was lower during treatment and its efficacy appeared to be greater.ConclusionsThe limitations notwithstanding our study-findings show that acupuncture was safe and effective in reducing pain intensity and symptoms-related disability. Larger-scale studies are needed to compare acupuncture and pharmacotherapy for endometriosis-related pain

Efficacy of Ginkgolide B in the prophylaxis of migraine with aura.

In a multicentric, open, preliminary trial, we evaluated the use of ginkgolide B, a herbal constituent extract from Ginkgo biloba tree leaves, in the prophylactic treatment of migraine with aura (MA). Fifty women suffering from migraine with typical aura, or migraine aura without headache, diagnosed according to International Headache Society criteria, entered a six-month study. They underwent a two month run-in period free of prophylactic drugs, followed by a four month treatment period (subdivided into two bimesters, TI and TII) with a combination of 60 mg ginkgo biloba terpenes phytosome, 11 mg coenzyme Q 10, and 8.7 mg vitamin B2 (Migrasoll), administered twice daily. A detailed diary reporting neurological symptoms, duration, and frequency of MA was compiled by patients throughout the trial. The number of MA significantly decreased during treatment (from 3.7 +/- 2.2 in the run-in period, to 2.0 +/- 1.9 during TI and to 1.2 +/- 1.6 during TII; Anova for repeated measures: P < 0.0001). There was also a statistically significant decrease in the average MA duration, which was 40.4 +/- 19.4 min during run-in, 28.2 +/- 19.9 during TI, and 17.6 +/- 20.6 during TII. Total disappearance of MA was observed in 11.1% patients during TI and in 42.2% of patients during T2. No serious adverse event was provoked by Migrasoll administration. Ginkgolide B is effective in reducing MA frequency and duration. The effect is clearly evident in the first bimester of treatment and is further enhanced during the second

Comparison of frovatriptan plus dexketoprofen (25 mg or 37.5 mg) with frovatriptan alone in the treatment of migraine attacks with or without aura: A randomized study

Background Drugs for migraine attacks include triptans and NSAIDs; their combination could provide greater symptom relief. Methods A total of 314 subjects with history of migraine, with or without aura, were randomized to frovatriptan 2.5 mg alone (Frova), frovatriptan 2.5 mg + dexketoprofen 25 mg (FroDex25) or frovatriptan 2.5 mg + dexketoprofen 37.5 mg (FroDex37.5) and treated at least one migraine attack. This was a multicenter, randomized, double-blind, parallel-group study. The primary end point was the proportion of pain free (PF) at two hours. Secondary end points were PF at one and four hours, pain relief (PR) at one, two, four hours, sustained PF (SPF) at 24 and 48 hours, recurrence at 48 hours, resolution of nausea, photophobia and phonophobia at two and four hours, the use of rescue medication and the judgment of the treatment. Results The results were assessed in the full analysis set (FAS) population, which included all subjects randomized and treated for whom at least one post-dose intensity of headache was recorded. The proportions of subjects PF at two hours (primary end point) were 29% (27/93) with Frova compared with 51% (48/95 FroDex25 and 46/91 FroDex37.5) with each combination therapies ( p < 0.05). Proportions of SPF at 24 hours were 24% (22/93) for Frova, 43% (41/95) for FroDex25 ( p < 0.001) and 42% (38/91) for FroDex37.5 ( p < 0.05). SPF at 48 hours was 23% (21/93) with Frova, 36% (34/95) with FroDex25 and 33% (30/91) with FroDex37.5 ( p = NS). Recurrence was similar for Frova (22%, 6/27), FroDex25 (29%, 14/48) and FroDex37.5 (28%, 13/46) ( p = NS), meaning a lack of improvement with the combination therapy. Statistical adjustment for multiple comparisons was not performed. No statistically significant differences were reported in the occurrence of total and drug-related adverse events. FroDex25 and FroDex37.5 showed a similar efficacy both for primary and secondary end points. There did not seem to be a dose response curve for the addition of dexketoprofen. Conclusion FroDex improved initial efficacy at two hours compared to Frova whilst maintaining efficacy at 48 hours in this study. Tolerability profiles were comparable. Intrinsic pharmacokinetic properties of the two single drugs contribute to this improved efficacy profile

Efficacy of frovatriptan versus other triptans in the acute treatment of menstrual migraine: pooled analysis of three double-blind, randomized, crossover, multicenter studies

The objective of this study was to review the efficacy and safety of frovatriptan (F) versus rizatriptan (R), zolmitriptan (Z) and almotriptan (A), in women with menstrually related migraine (IHS criteria) through a pooled analysis of three individual studies. Subjects with a history of migraine with or without aura were randomized to F 2.5 mg or R 10 mg (study 1), F or Z 2.5 mg (study 2), and F or A 12.5 mg (study 3). The studies had an identical multicenter, randomized, double-blind, crossover design. After treating three episodes of migraine in no more than 3 months with the first treatment, patients had to switch to the next treatment for other 3 months. 346 subjects formed intention-to-treat population of the main study; 280 of them were of a female gender, 256 had regular menses and 187 were included in the menstrual migraine subgroup analysis. Rate of pain free at 2, 4 and 24 h was 23, 52 and 67 % with F and 30, 61 and 66 % with comparators (P = NS). Pain relief episodes at 2, 4 and 24 h were 37, 60 and 66 % for F and 43, 55 and 61 % for comparators (P = NS). Rate of recurrence was significantly (P < 0.05) lower under F either at 24 h (11 vs. 24 % comparators) or at 48 h (15 vs. 26 % comparators). Number of menstrual migraine attacks associated with drug-related adverse events was equally low (P = NS) between F (5 %) and comparators (4 %)
