How Does Zolmitriptan Work?

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