Like all triptans, almotriptan has a high and specific affinity for serotonin 5-HT 1B/1D receptors. Binding of the drug to the receptor leads to vasoconstriction of the cranial (brain) blood vessels and thus affects the redistribution of blood flow. Almotriptan significantly increases cerebral blood flow and reduces blood flow through ...

[2] These medications are selective 5-HT 1B/1D receptor agonists with some activity at 5-HT 1F.
