There remains a great need for more effective anti-migraine drugs with fewer side effects. Human experimental models are valuable in early phase development of new anti-migraine drugs but useful models have not yet been developed. The investigators' group has shown that Isosorbide-5-mononitrate (5-ISMN), a long lasting NO-donor, induce headache/migraine in both healthy volunteers and in patients with migraine without aura (MO). To validate this model, the headache must respond to specific migraine treatment with sumatriptan.
Hypothesis: 5-ISMN induces a migraine-like headache in both healthy subjects and in MO-patients and induced headache responds to a specific anti migraine drug; sumatriptan.
Aim: Developing a pragmatic and valid model for the testing of new anti-migraine drugs
