title: Cytochrome P-450-dependent hydroxylation in migraine.
abstract: The hypothesis was tested that an acute oxidation deficiency related to potential dietary trigger factors plays a role in the migraine attack. Migraine sufferers (14F and 4M), fulfilling the criteria for migraine with and without aura according to the classification of the International Headache Society, were coadministered oral mephenytoin (100 mg) and debrisoquine (10 mg) during the initial phase of a typical migraine attack. This was repeated during a period without migraine. The hydroxylation of mephenytoin and debrisoquine hydroxylation did not differ during and without the migraine attack. We conclude that hydroxylation, via cytochrome P-450 (2D6, 2C8 and 9), is not reduced during the migraine attack. The results do not support the hypothesis that oxidation deficiency is involved in the pathophysiology of migraine.
