Sumatriptan is a new 5HT1-like agonist that has proved a novel and effective treatment for migraine. The disposition of the 14C-radiolabeled drug in laboratory animals and humans after oral and parenteral administration is described. Oral absorption of sumatriptan is essentially complete in dogs and rabbits, but only approximately 50% in rat. In humans, at least 57% of an oral dose is absorbed.
