Eletriptan, Relpax is a selective agonist for serotonin 5-HT1B and 5-HT1D receptors. These are located on intracranial blood vessels and sensory nerves of the trigeminal system and activating these receptors causes vasoconstriction and reduces neurogenic inflammation associated with antidromic neuronal transmission. These actions are thought to be the cause of migraine relief.
