Treatment for Cluster Headache
Sumatriptan, a selective serotonin receptor (5-HT1B/1D) agonist, acts by causing vasoconstriction of cranial blood vessels and inhibiting neurogenic inflammation in cluster headache treatment. It rapidly reduces pain intensity by binding to receptors in the trigeminal system, thereby interrupting the neurological cascade associated with headache pathogenesis and providing quick symptomatic relief.
