nasal medication
Treatment for Cluster Headache
Nasal medication for Cluster Headache, such as sumatriptan nasal spray, acts as a selective serotonin 5-HT1B/1D receptor agonist that constricts cranial blood vessels and inhibits pro-inflammatory neuropeptide release. The rapid absorption through the nasal mucosa allows for quick onset of action, providing swift relief by reducing neurovascular inflammation and alleviating pain through direct central nervous system modulation.
