How Does Naratriptan Work?

Naratriptan is part of a class of migraine medications called 5-HT agonists (also referred to as "triptans"). During a migraine headache, some of the blood vessels in the head become dilated (wider than they usually are). Naratriptan works by narrowing these blood vessels, helping them return to their normal state. This action helps to relieve migraine symptoms.
