Imitrex Indication:

For the treatment of migraine attacks with or without aura in adults

Imitrex Mechanism Of Action:

Imitrex stimulates 5-HT receptors of the 1D subtype, most likely presynaptic receptors, resulting in selective vasoconstriction of inflamed and dilated cranial blood vessels in the carotid circulation. Imitrex also blocks the release of vasoactive neuropeptides from perivascular trigeminal axons in the dura mater during migraine and may inhibit the release of inflammatory mediators from the trigeminal nerve.
