Treatment for Cluster Headache
Sumatriptan, a selective serotonin receptor agonist (5-HT1B/1D receptor), acts by constricting cranial blood vessels and inhibiting pro-inflammatory neuropeptide release in the trigeminal system. It rapidly alleviates cluster headache symptoms by reducing neurovascular inflammation and blocking pain signal transmission, providing fast-acting relief for acute cluster headache episodes.
