The iontophoretic transdermal system formulation of sumatriptan as a new option in the acute treatment of migraine: a perspective

An iontophoretic transdermal system (ITS) (skin patch) formulation of sumatriptan for the acute treatment of migraine attacks was approved by the US Food and Drug Administration in January 2013. This transdermal system bypasses the gastrointestinal tract, as it uses low electrical current to move sumatriptan transdermally into the subcutaneous tissue. Randomized, double-blind, controlled clinical trials have demonstrated minimal triptan-related side effects and superior efficacy versus placebo, comparable with other sumatriptan formulations. Sumatriptan ITS can be applied successfully during a mild or severe migraine attack. According to pharmacokinetic properties and clinical data, sumatriptan ITS may be a good choice for people with migraine and severe nausea, vomiting or gastroparesis, those with intolerable triptan-related adverse events and those not responding optimally to oral medications

Results of a Web-Based Survey on 2105 Greek Migraine Patients—Second Part: Efficacy of Acute and Prophylactic Migraine Treatments and Corresponding Patients’ Reported Satisfaction

Background and Objectives: The Greek Society of Migraine and Headache Patients conducted, in 2020, its second online survey, titled “Migraine in Greece—2020”, after publication of the first similar online survey conducted in 2018. To compare the current findings with the corresponding data obtained in 2018, we herein release the second part of results obtained from the 2020 survey on the efficacy of preventive and symptomatic anti-migraine medications and the patients’ reported satisfaction with these treatments. Materials and Methods: We surveyed 2105 migraine patients from all over Greece with the use of a 151-questions specific migraine-focused questionnaire in Greek language, which was distributed through the online research software “SurveyMonkey”. Results: Triptans were mostly used with efficacy for the symptomatic relief of migraine attacks. About 2 of 3 surveyed patients had received various prophylactic oral medications and the majority of them discontinued these prophylactic medications as a result of inefficacy/safety issues. BoNTA was reported to be effective only when administration was commenced by a trained neurologist/headache specialist, while our current findings are generally comparable to those obtained in our 2018 pre-COVID-19 survey and the pandemic has not imposed any significant attitudes on migraine therapies and corresponding patients’ satisfaction. Conclusion: Although a market change is anticipated with the evolving widespread use of anti-CGRPs monoclonal antibodies or gepants in the symptomatic and prophylactic treatment of migraine, it is of great interest to review published results of larger longitudinal population-based studies to further ascertain the satisfaction of patients to migraine therapies

Sustained onabotulinumtoxinA therapeutic benefits in patients with chronic migraine over 3 years of treatment

Abstract Background Evidence on whether the therapeutic effect and good safety profile of onabotulinumtoxinA (Botox®) in chronic migraine (CM) patients is maintained over long term treatment is still limited. We herein aimed at assessing whether there is a sustained benefit and good safety with repeated onabotulinumtoxinA sessions in CM over more than three years of treatment. Methods We prospectively enrolled 65 CM patients, who were classified as responders after three sessions of onabotulinumtoxinA and were eligible to further continue treatment. Data documenting longitudinal changes from the trimester after the third onabotulinumtoxinA administration (T1) to the trimester after completing two years of treatment (T2) and eventually to the trimester after completing three years of treatment (T3) in (i) mean number of monthly headache days (ii) migraine severity as expressed by the mean number of days with peak headache intensity of > 4/10, and (iii) mean number of days with use of any acute headache medication, were prospectively collected from patients’ headache diaries. Results A total of 56 (86.1%) of 65 patients achieved to attain onabotulinumtoxinA over three years. At T3, a significant reduction in mean monthly headache days was evident, compared to T1 (3.4 ± 1.7 vs 7.2 ± 3.8; P < 0.001) with diminished mean number of monthly days with peak headache intensity of more than 4/10 and a significant change in days using acute headache medications per month between T1 and T3 (2.8 ± 1.3 vs 4.7 ± 3.2; P < 0.001). Significant changes were also noticed in all efficacy variables from T2 to T3. Therapy was safe and well tolerated with low rates of adverse events or drop-outs. Conclusion The long -term treatment with onabotulinumtoxinA proved effective, safe and well tolerated over three years. Our findings support the strategy to consistently deliver sessions of use of onabotulinumtoxinΑ over long time in CM patients (Trial registration NTC03606356, registered retrospectively, 28 July 2018)

Clinical experience with transcutaneous supraorbital nerve stimulation in patients with refractory migraine or with migraine and intolerance to topiramate: a prospective exploratory clinical study

Abstract Background Migraine is included in the top-ten disabling diseases and conditions among the Western populations. Non-invasive neurostimulation, including the Cefaly® device, for the treatment of various types of pain is a relatively new field of interest. The aim of the present study was to explore the clinical experience with Cefaly® in a cohort of migraine patients previously refractory or intolerant to topiramate prophylaxis. Methods A prospective, multi-center clinical study was performed in patients diagnosed with episodic or chronic migraine with a previous failure to topiramate treatment requiring prevention with Cefaly® according to the treating physician’s suggestion. A 1-month period of baseline observation was followed by a 3-month period of observation during the use of transcutaneous supraorbital nerve stimulation (t-SNS) with Cefaly® as the only preventive treatment. Results A small but statistically significant decline was shown over time in the number of days with headache (HA), the number of days with HA with intensity ≥5/10, and the number of days with use of acute medication after 3 months (p < 0.001 for all of the three changes). Twenty-three patients (65.7%) expressed their satisfaction and intent to continue treatment with Cefaly®. Compliance was higher among satisfied subjects compared to non-satisfied subjects. None of the explored factors were significantly associated with the reason for the failure of topiramate. Conclusion Three-months of preventive treatment for episodic or chronic migraine with t-SNS proved to be an effective, safe and well tolerated option for the treatment of patients with migraine who were intolerant or did not respond to topiramate.

Open Label Prospective Experience of Supplementation with a Fixed Combination of Magnesium, Vitamin B2, Feverfew, Andrographis Paniculata and Coenzyme Q10 for Episodic Migraine Prophylaxis

Background: To investigate the efficacy and safety of supplementation with a fixed combination of magnesium, vitamin B2, feverfew, andrographis paniculata and coenzyme Q10 in episodic migraine (EM) prevention. Methods: A pilot, single-arm, open-label study was conducted. After a one-month baseline period, the above-described supplementation was introduced in 113 EM Greek patients, who were prospectively followed-up for three months. The primary endpoint was the change in monthly migraine days between baseline period (BSL) and the third month of supplementation (T3). Secondary endpoints included changes in mean intensity of migraine and in days with use of acute migraine medications. Changes in scores of Migraine Disability Assessment questionnaire (MIDAS), Headache Impact Test-6 (HIT-6), Migraine Therapy Assessment questionnaire (MTAQ), Migraine-Specific Quality-of-life questionnaire (MSQ-QOL), Hospital Anxiety and Depression Scale (HADS) were also evaluated. Those with &ge;50% reduction in monthly migraine days at T3, compared to BSL were considered supplementation-responders. Results: The mean number of migraine days was significantly decreased between BSL and T3 (9.4 &plusmn; 3.7 vs. 6.1 &plusmn; 3.5; p &lt; 0.001). Likewise, days with peak headache intensity of &gt;4/10 (5.7 &plusmn; 3.4 vs. 4.9 &plusmn; 3.1; p &lt; 0.001) as well as days using acute headache medications per month (8.9 &plusmn; 3.6 vs. 5.7 &plusmn; 3.4; p &lt; 0.001) were significantly reduced. At T3, 64 patients (56.6%) were classified as responders. The beneficial effect of supplementation was also associated with significant changes in HIT-6, MIDAS, MTAQ and MSQ-QOL scores. There were no safety concerns. Conclusions: The supplementation we have tested appears to be an effective and well-tolerated preventive approach against EM. A randomized, placebo-controlled study is needed to confirm our results
