Clinical Trial Controlled Clinical Trial
Glyceryl trinitrate induces attacks of migraine without aura in sufferers of migraine with aura.
Migraine with aura and migraine without aura have the same pain phase, thus indicating that migraine with aura and migraine without aura share a common pathway of nociception. In recent years, increasing evidence has suggested that the messenger molecule nitric oxide (NO) is involved in pain mechanisms of migraine without aura. In order to clarify whether the same is true for migraine with aura, in the present study we examined the headache response to intravenous infusion of glyceryl trinitrate (GTN) (0.5 microg/kg/min for 20 min) in 12 sufferers of migraine with aura. ⋯ At this time the induced headache in 6 of 12 migraineurs fulfilled the diagnostic criteria for migraine without aura of the International Headache Society. The results therefore suggest that NO is involved in the pain mechanisms of migraine with aura. Since cortical spreading depression has been shown to liberate NO in animals, this finding may help our understanding of the coupling between cortical spreading depression and headache in migraine with aura.

Randomized Controlled Trial Comparative Study Clinical Trial
Treatment of severe, disabling migraine attacks in an over-the-counter population of migraine sufferers: results from three randomized, placebo-controlled studies of the combination of acetaminophen, aspirin, and caffeine.
To examine the benefits of acetaminophen, aspirin, and caffeine (AAC) in the treatment of severe, disabling migraine attacks, in a population of migraine sufferers for whom over-the-counter (OTC) medications are appropriate. ⋯ The nonprescription combination of AAC was well tolerated and effective.
