Sumatriptan-naproxen more effective than placebo when menstrual migraine treated early in the course of a migraine attack – two studies
Summary of the results:
Pain free after two hours
Study 1: active drug = 42%; placebo = 23%
Study 2: active drug = 52%; placebo = 22%
2-24 hour sustained pain free (of those pain free at 2 hours, what percent remained pain free until 24 hours)
Study 1: active drug = 29%; placebo = 18%
Study 2: active drug = 38%; placebo = 10%

Summary of the abstract
OBJECTIVE: To evaluate the efficacy and tolerability of sumatriptan-naproxen during the mild pain phase of a single menstrual migraine attack associated with dysmenorrhea.
METHODS: Participants treated their menstrual migraine attack during the mild pain phase (within 1 hour of onset) with sumatriptan 85 mg and naproxen sodium 500 mg in a single fixed-dose formulation (sumatriptan-naproxen) or placebo. The primary endpoint was 2-hour pain-free response.
RESULTS: Sumatriptan-naproxen was statistically superior to placebo in both studies (n=311, Study 1; n=310, Study 2) for 2-hour and, 2- to 24-hour sustained pain-free response, use of headache and menstrual rescue medications, and several nonpain menstrual symptom categories.
Two-hour pain-free rates were Study 1, 42% compared with 23%, and Study 2, 52% compared with 22%, P<.001.
Two- to 24-hour sustained pain-free rates were Study 1, 29% compared with 18%, P=.022; Study 2, 38% compared with 10%, P<.001.
Headache and menstrual medication rates were Study 1, 37% compared with 53%, P=.005; Study 2, 31% compared with 69%, P<.001.
Women treated with sumatriptan-naproxen continued to be pain free through 48 hours compared with placebo: Study 1, 26% compared with 17%, P=.040; Study 2, 28% compared with 8%, P<.001.
No serious adverse events were reported.
CONCLUSION: Sumatriptan-naproxen provided an effective pain-free response at 2 hours, which was maintained up to 48 hours in menstrual migraineurs with dysmenorrhea. Sumatriptan-naproxen was well-tolerated and resulted in decreased rescue medication use and relief of nonpainful menstrual symptoms.
