The Effect of Sumatriptan and Placebo on Isosorbide-5-mononitrate Induced Headache

2015-07-01 07:23:22 | BioPortfolio


To develop a pragmatic migraine model the investigators will induce headache in healthy volunteers and in patients with migraine without aura with a long lasting NO donor. If the headache responds to sumatriptan, the model can be used to test new drug candidates.


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

Medical and Biotech [MESH] Definitions

A serotonin agonist that acts selectively at 5HT1 receptors. It is used in the treatment of MIGRAINE DISORDERS.

A class of disabling primary headache disorders, characterized by recurrent unilateral pulsatile headaches. The two major subtypes are common migraine (without aura) and classic migraine (with aura or neurological symptoms). (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)

A subtype of migraine disorder, characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred VISION; HALLUCINATIONS; VERTIGO; NUMBNESS; and difficulty in concentrating and speaking. Aura is usually followed by features of the COMMON MIGRAINE, such as PHOTOPHOBIA; PHONOPHOBIA; and NAUSEA. (International Classification of Headache Disorders, 2nd ed. Cephalalgia 2004: suppl 1)

1,4:3,6-Dianhydro D-glucitol. Chemically inert osmotic diuretic used mainly to treat hydrocephalus; also used in glaucoma.

A vasodilator used in the treatment of ANGINA PECTORIS. Its actions are similar to NITROGLYCERIN but with a slower onset of action.
