triptan injection
Treatment for Cluster Headache
Triptans are selective serotonin receptor (5-HT1B/1D) agonists that cause vasoconstriction of cranial blood vessels and inhibit neurogenic inflammation. When injected for cluster headache, they rapidly reduce pain by binding to receptors in the trigeminal system, providing quick relief from acute headache symptoms through their vasoconstrictive and neurotransmitter-modulating properties.
