Treatment for Cluster Headache
Injection therapy for Cluster Headache typically involves sumatriptan or dihydroergotamine, which act as selective serotonin receptor (5-HT1B/1D) agonists. These medications rapidly constrict cranial blood vessels, inhibit neurogenic inflammation, and interrupt pain signal transmission in the trigeminovascular system, providing fast and targeted relief of acute cluster headache symptoms.
