Comparing the Efficacy of Eletriptan for Migraine in WomenDuring Menstrual and Non-Menstrual Time Periods: A PooledAnalysis of Randomized Controlled TrialsRahul Bhambri, PharmD; Vincent T. Martin, MD; Younos Abdulsattar, PharmD, BCPS;Stephen Silberstein, MD; Mary Almas, MS; Anjan Chatterjee, MD, MPH*; Elodie Ramos, PhDObjective.—To assess the efficacy and tolerability of eletriptan in treating migraine attacks occurring within the definedmenstrual time period of 1 day before and 4 days after onset of menstruation (menses days –1 to +4) compared with attacksoccurring during non-menstrual time periods (occurring outside of menses days –1 to +4).Background.—Migraine attacks during menses have been associated with longer duration, higher recurrence rates, greatertreatment resistance, and greater functional disability than those not associated with menses. The efficacy of eletriptan intreating migraine attacks associated with menstruation vs those outside a defined menstrual period has not been evaluated.Methods.—Data were pooled from 5 similarly designed, double-blind, randomized, placebo-controlled trials of eletriptan20 mg/40 mg/80 mg. Two groups were defined for this analysis: women with a single index migraine beginning during themenstrual (group 1) and non-menstrual (group 2) time periods. End points of interest were headache response at 2 hours,migraine recurrence and sustained responses for nausea, photo/phonophobia, and function. Logistic regression was used tocompare group 1 vs group 2 and each eletriptan dose (20, 40, or 80 mg) vs placebo. Adverse events were also assessed.Results.—Of 3217 subjects pooled from 5 studies, 2216 women were either in group 1 (n = 630) or group 2 (n = 1586). Ratesof headache response at 2 hours were similar in group 1 vs group 2 (odds ratio [OR] = 1.11 [95% confidence interval (CI) 0.91,1.36]; P = .2944). The rate of headache recurrence was significantly higher in group 1 vs group 2 (26.8% vs 18.6%; OR = 1.67[95% CI 1.23, 2.26]; P < .001). The odds of achieving sustained nausea responses were significantly lower in group 1 than ingroup 2 (OR = 0.70 [95% CI 0.54, 0.92]; P = .0097). There was no significant difference between group 1 and group 2 in the oddsof achieving a sustained photo/phonophobia and functional response (OR = 0.96 [95% CI 0.77, 1.20]; P = .7269 and OR = 1.14[95% CI 0.87, 1.50]; P = .3425, respectively). Adverse events were comparable between group 1 and group 2.Conclusions.—Two-hour headache outcome measures were similar in women treated with eletriptan both within andoutside of the defined menstrual time period (menses days –1 to +4). The main treatment differences between the 2 groupsoccurred 2-24 hours post-treatment, with higher recurrence rates and lower sustained response rates for nausea in the grouptreated during the menstrual time period.Key words: eletriptan, headache, migraine, menses, menstrual migraine, triptanAbbreviations: AE adverse event, CI confidence interval, ICHD International Classification of Headache Disorders, ICHD-3
