Treatment for Cluster Headache
Sumatriptan, a selective serotonin receptor (5-HT1B/1D) agonist, acts by causing vasoconstriction of cranial blood vessels and inhibiting neuropeptide release in the trigeminal system. When administered via subcutaneous injection or nasal spray, it rapidly alleviates acute cluster headache symptoms by reducing inflammation and blocking pain transmission pathways in the central nervous system.
