Dihydroergotamine drug class?

What drug class is dihydroergotamine in?

Dihydroergotamine (DHE) belongs to the ergot alkaloid drug class. These medicines are derived from ergot (a fungus) and act on serotonin and dopamine receptors, which can affect blood vessel tone and related migraine and vascular symptoms.

Why is dihydroergotamine used (and what class does that suggest)?

Dihydroergotamine is most commonly used in migraine therapy. Because it comes from the ergot alkaloids, it is generally discussed with other “ergot” migraine medicines (often in the same therapeutic category of antimigraine agents that act on vascular and neurologic pathways).

Is dihydroergotamine a triptan or an ergot like ergotamine?

Dihydroergotamine is an ergot alkaloid, not a triptan. Triptans (such as sumatriptan) are a different class of antimigraine drugs. DHE is related to ergotamine, which is another ergot alkaloid used for migraine.

Does dihydroergotamine count as a vasoconstrictor?

Yes. Ergot alkaloids like dihydroergotamine are associated with vasoconstrictive activity, which is part of why they have activity in migraine and certain other conditions involving abnormal vascular responses.
