ABSTRACT To evaluate the long-term safety and tolerability of sumatriptan-naproxen sodium for the treatment of moderate to severe acute migraines and to assess the safety of administration of an optional second dose.
A 12-month, multicenter, open-label safety study was conducted in adults treated for migraine attacks of moderate to severe intensity from April 14, 2004, to August 18, 2005. Safety evaluations included adverse events and laboratory tests.
Of 600 patients enrolled, 565 (94%) were treated for at least 1 migraine. Of treated patients, 414 (73%) and 362 (64%) completed 6 and 12 months of treatment, respectively. Of the 24,485 attacks treated, 17,144 (70%) were treated with only 1 dose. On average, patients treated 5 migraine attacks per month, with a median of 6 days between attacks. The most common treatment-related adverse events were nausea, muscle tightness, and dizziness. Fourteen patients reported 1 or more serious adverse event with only 1 judged probably related to treatment. No deaths occurred. Eight percent of patients discontinued participation in the study because of adverse events or pregnancy. The rates of adverse events reported were no higher after treatment with 2 tablets (at least 2 hours apart) compared with 1 tablet.
In this 12-month data set of more than 24,000 migraine attacks in 565 patients, sumatriptan-naproxen sodium formulated in a single tablet was well tolerated when used episodically for the treatment of acute migraine. The adverse events did not differ from those expected for the individual components alone, and no new or unexpected findings occurred.

    ABSTRACT: Multiple pathogenic mechanisms may be involved in generating the migraine symptom complex, and multimechanism-targeted therapy may confer advantages over monotherapy. To evaluate the efficacy and safety of a fixed-dose tablet containing sumatriptan succinate and naproxen sodium relative to efficacy and safety of each monotherapy and placebo for the acute treatment of migraine. Two replicate, randomized, double-blind, single-attack, parallel-group studies conducted among 1461 (study 1) and 1495 (study 2) patients at 118 US clinical centers who were diagnosed as having migraine and received study treatment for a moderate or severe migraine attack. Patients were randomized in a 1:1:1:1 ratio to receive a single tablet containing sumatriptan, 85 mg, and naproxen sodium, 500 mg; sumatriptan, 85 mg (monotherapy); naproxen sodium, 500 mg (monotherapy); or placebo, to be used after onset of a migraine with moderate to severe pain. Primary outcome measures included the percentages of patients with headache relief 2 hours after dosing, absence of photophobia, absence of phonophobia, and absence of nausea for the comparison between sumatriptan-naproxen sodium and placebo, and the percentages of patients with sustained pain-free response for the comparison between sumatriptan-naproxen sodium and each monotherapy. Sumatriptan-naproxen sodium was more effective than placebo for headache relief at 2 hours after dosing (study 1, 65% vs 28%; P<.001 and study 2, 57% vs 29%; P<.001), absence of photophobia at 2 hours (58% vs 26%; P<.001 and 50% vs 32%; P<.001), and absence of phonophobia at 2 hours (61% vs 38%; P<.001 and 56% vs 34%; P<.001). The absence of nausea 2 hours after dosing was higher with sumatriptan-naproxen sodium than placebo in study 1 (71% vs 65%; P = .007), but in study 2 rates of absence of nausea did not differ between sumatriptan-naproxen sodium and placebo (65% vs 64%; P = .71). For 2- to 24-hour sustained pain-free response, sumatriptan-naproxen sodium was superior at P<.01 (25% and 23% in studies 1 and 2, respectively) to sumatriptan monotherapy (16% and 14% in studies 1 and 2), naproxen sodium monotherapy (10% and 10% in studies 1 and 2), and placebo (8% and 7% in studies 1 and 2). The incidence of adverse events was similar between sumatriptan-naproxen sodium and sumatriptan monotherapy. Sumatriptan, 85 mg, plus naproxen sodium, 500 mg, as a single tablet for acute treatment of migraine resulted in more favorable clinical benefits compared with either monotherapy, with an acceptable and well-tolerated adverse effect profile. Identifiers: NCT00434083 (study 1); NCT00433732 (study 2).

    ABSTRACT: Migraine is the most common headache complaint in clinical practice. Part 1 of a two-part series presents a summary of treatments used to reduce the severity and duration of migraine and its associated symptoms and also discusses the comorbidities, clinical presentation, and risk factors associated with this affliction.

    ABSTRACT: Menstrual disorders affect millions of women in the United States and represent an important health burden. The most common menstrual disorders are dysmenorrhea and headache; these conditions are leading causes of work or school absenteeism and substantially impact quality of life. Headache associated with menses is often migraine and referred to as menstrual migraine. Although the pathogenesis of menstrual-related pain conditions is not fully understood, menstrual-related overproduction of prostaglandins is implicated in the pathophysiology of both menstrual migraine and dysmenorrhea. In clinical practice, nonsteroidal anti-inflammatory drugs (NSAIDs) are considered the first-line therapeutic option for managing pain associated with dysmenorrhea. NSAIDs also play a role in the acute treatment and intermittent prophylaxis of migraine. Triptans, a class of highly selective serotonin receptor agonists, represent the gold standard for acute treatment of migraine. In addition, hormone therapy is effective in many cases for treating dysmenorrhea and may be beneficial in the management of menstrual migraine. Thus, overlapping treatment regimens may be advantageous in treating the coexisting menstrual-related pain conditions of dysmenorrhea and migraine.
