The present study was designed to discern the prevalence of concomitant use of a 5-hydroxytryptamine receptor agonist (triptan), and a selective serotonin reuptake inhibitor (SSRI) or a selective serotonin/norepinephrine reuptake inhibitor (SNRI) after the US Food and Drug Administration issued an alert regarding serotonin syndrome in 2006 and to contrast findings with data published prior to the federal warning. ⋯ Our study documents that 1.8% (1,319,763/73,860,558) of patients in 2007-2008 were prescribed triptan, and SSRI or SNRI (vs 1.3% in 2003-04, an increase of 38.5%). While this is a small fraction overall, the actual number of patients on a nationwide basis is substantial. What remains missing from the literature is documentation as to the number of cases of serotonin syndrome and resulting consequences (clinical and economic) because of the concomitant use of triptan, and SSRI or SNRI in the time-frame 2007-2008. Absent in these data, it remains difficult to assess the risk benefit associated with the use of triptan, and SSRI or SNRI.

Randomized Controlled Trial Multicenter Study
Rizatriptan for treatment of acute migraine in patients taking topiramate for migraine prophylaxis.
To assess efficacy and tolerability of rizatriptan orally disintegrating tablet (ODT) for treatment of acute migraine in patients using topiramate for migraine prophylaxis. ⋯ Rizatriptan 10-mg ODT was superior to placebo at all pain end points for treatment of acute migraine in patients using topiramate for migraine prophylaxis. Rizatriptan was generally well tolerated in this population. These results are comparable with those from clinical trials in patients not using prophylaxis, suggesting that the use of topiramate does not affect the efficacy or tolerability of rizatriptan for acute migraine treatment.

This study evaluated the effectiveness of a single fixed-dose tablet of sumatriptan 85 mg/naproxen sodium 500 mg (sumatriptan-naproxen) using a very early treatment paradigm in migraine patients whose attacks were historically accompanied by cutaneous allodynia. ⋯ In this open-label study, allodynic patients reported that their migraine attacks responded well and they achieved a high degree of satisfaction following treatment with a fixed-dose tablet of sumatriptan 85 mg/naproxen sodium 500 mg administered in a very early treatment paradigm.

The Headache Impact Test-6 (HIT-6) has been demonstrated to be a reliable and valid measure that assesses the impact of headaches on the lives of persons with migraine. Originally used in studies of episodic migraine (EM), HIT-6 is finding increasing applications in chronic migraine (CM) research. ⋯ This work further establishes HIT-6 as a useful instrument for characterizing CM and understanding the increased disease related burden. Persons with CM had significantly higher odds of greater adverse headache impact, when compared with EM. Predictors of greater headache impact for both groups included higher MSS scores, higher average headache pain severity, and depression. Additional predictors unique to EM included higher average household income, younger age, higher standardized headache day frequency, and anxiety. This finding may be related to differences in sample size and power. Further exploration is warranted.

To assess the frequency of opioid use for acute migraine treatment and characterize use groups by sociodemographics, health-care resource utilization (HRU), comorbidities and probable dependence within a large, US population-based sample of persons with migraine. ⋯ Opioid use for migraine is associated with more severe headache-related disability, symptomology, comorbidities (depression, anxiety, and cardiovascular disease and events), and greater HRU for headache. Longitudinal studies are needed to further assess the directionality and causality between opioid use and the outcomes we examined.
