Eletriptan is a triptan used for the treatment of migraines.
Eletriptan binds with high affinity to 5-HT1B, 5-HT1D and 5-HT1F receptors, has modest affinity for 5-HT1A, 5-HT1E, 5-HT2B and 5-HT7 receptors, and little or no affinity for 5-HT2A, 5-HT2C, 5-HT3, 5-HT4, 5-HT5A and 5-HT6 receptors. In contrast, eletriptan displays insignificant pharmacological activity at adrenergic alpha1, alpha2, or beta; dopaminergic D1 or D2; muscarinic; or opioid receptors. While the full mechanism of action of 5-HT receptor agonists in relieving migrains is not fully elucidated, it is proposed that the activation of 5-HT1 receptors located on intracranial blood vessels leads to vasoconstriction that correlates with the relief of migraine headaches. It is also proposed that the activation of 5-HT1 receptors on sensory nerve endings in the trigeminal system leads to the inhibition of release of pro-inflammatory neuropeptides.
